  • PlayStation 5

    The PlayStation 5 (PS5) is a home video game console developed by Sony Interactive Entertainment. It was announced as the successor to the PlayStation 4 in April 2019, was launched on November 12, 2020, in Australia, Japan, New Zealand, North America, and South Korea, and was released worldwide a week later. The PS5 is part of the ninth generation of video game consoles, along with Microsoft‘s Xbox Series X/S consoles, which were released in the same month.

    The base model includes an optical disc drive compatible with Ultra HD Blu-ray discs. The Digital Edition lacks this drive, as a lower-cost model for buying games only through download. The two variants were launched simultaneously. Slimmer hardware revisions of both models replaced the original models on sale in November 2023.[10] A PlayStation 5 Pro model was released on November 7, 2024, featuring a faster GPU, improved ray tracing, and introducing an AI-driven upscaling technology.

    The PlayStation 5’s main hardware features include a solid-state drive customized for high-speed data streaming to enable significant improvements in storage performance, an AMD GPU capable of 4K resolution display at up to 120 frames per second, hardware-accelerated ray tracing for realistic lighting and reflections, and the Tempest Engine for hardware-accelerated 3D audio effects. Other features include the DualSense controller with haptic feedbackbackward compatibility with the majority of PlayStation 4 and PlayStation VR games, and the PlayStation VR2 headset.

    History

    Development

    Mark Cerny, chief architect of PlayStation 5

    The lead architect of the PlayStation console line, Mark Cerny, implemented a two-year feedback cycle after the launch of the PlayStation 4. This entailed regularly visiting Sony’s first-party developers at two-year intervals to find out what concerns they had with shortcomings in Sony’s current hardware and how such hardware could be improved in console refreshes or for the next generation. This feedback directly influenced the priorities of the console development team. During the development of the PlayStation 5, a central challenge revolved around addressing the length of loading times for games.[11] Cerny said several developers, including Epic Games‘ Tim Sweeney, told him that standard I/O speed of a hard disk drive was now a limiting factor in pushing game development.[12] Slow data rates placed limits on the size of data being loaded into the game, the physical location of data on the storage medium, and the duplication of data across the medium in order to reduce load times. An important goal was to find ways to reduce loading time, particularly in games that stream or dynamically load new game areas as the player moves through the game world.[11]

    Jim Ryan, then CEO of Sony Interactive Entertainment, stated that Sony had researched the feasibility of a “low priced, reduced spec” version of the PlayStation 5, like what Microsoft had done with its lower-power counterpart to the Xbox Series X, the Xbox Series S, and concluded that they believed such consoles do not fare well, becoming obsolete too fast.[13]

    Marketing and release

    Cerny first publicly described the new console in an interview with Wired magazine in April 2019.[14] In early 2019, Sony’s financial report for the quarter ending March 31, 2019, affirmed that new next-generation hardware was in development but would ship no earlier than April 2020.[15] In a second Wired magazine interview in October 2019, Sony said it intended to ship its next-generation console worldwide by the end of 2020.[16] The current hardware specifications were revealed in October 2019.[17][18] At CES 2020, Sony unveiled the official logo for the platform, which follows the similar minimalist styling of the previous PlayStation consoles and brand.[19] Full specifications were given in an online presentation by Cerny and published by Sony and Digital Foundry on March 18, 2020.[20][21][22] Digital Foundry spoke with Cerny in detail and published a “deep dive” on April 2.[23]

    A major game library showcase had been planned for June 4, 2020, but was postponed until June 11 due to the George Floyd protests. This presentation was also the premiere of the console’s external hardware design.[24][25][26][27]

    Event lighting being set up at SIE headquarters on the evening of November 8, 2020; four days before the launch

    Sony planned to launch the PlayStation 5 by the 2020 end-of-year holiday period.[28]

    PlayStation 5 Sales by Country: (as of March 2025):  Available  Officially sold but currently not supported by PlayStation Services, including PlayStation Network and PlayStation Store (the Philippines[29][30] and Vietnam[31])  Suspended by Sony (Russia)  Unavailable

    The date and pricing was confirmed as part of a game showcase presentation on September 16, 2020; the release date in Australia, Japan, New Zealand, North America, and South Korea was confirmed for November 12, 2020, and for most of the rest of the world on November 19, 2020.[32] The console was launched in the Philippines on December 11, 2020.[33]

    PlayStation 5’s release in India was delayed, leading to speculation that a trademark dispute was the reason; the name “PS5” was briefly trademarked by a different person; eventually the dispute was resolved and the system released there on February 2, 2021.[34][35][36][37] The console launched in Indonesia on January 22, 2021.[38] The system launched in China on May 15, 2021.[39]

    The console launched with two models: a base version with an Ultra HD Blu-ray compatible optical disc drive for retail game support alongside online distribution via the PlayStation Store, and a lower-cost variant lacking the disc drive and retaining digital download support.[40]

    Following the September 16, 2020, presentation, Sony stated that pre-orders for the console were to open at various retailers on the following day. However, several retailers in the United States and the United Kingdom launched pre-orders that evening, causing a rush on pre-orders, including scalping as many stores’ inventories were quickly sold out, and creating confusion. Sony apologized for the incident on September 19, 2020, and promised to increase more pre-order deliveries over the coming days and stock through the end of the year.[41][42]

    Worldwide supply of the console remained low due to a global chip shortage from 2020 to 2023.[43] Sony expected a short retail stock until 2023;[44] the company said that the supply chain issues were fixed.[45] In August 2022, Sony announced a price increase by up to 20% in most of its markets except the US, citing global economic, inflationary, and supply chain pressures.[46][47]

    Hardware

    Die shot of the PlayStation 5’s SoC

    The PlayStation 5 is powered by a custom system on a chip (SoC) designed in tandem by AMD and Sony,[48] integrating a custom 7 nm AMD Zen 2 CPU with eight cores running at a variable frequency capped at 3.5 GHz.[49] Zen 2 is a 64-bit x86-64 instruction set CPU microarchitecture. The integrated GPU is also a custom unit based on AMD’s RDNA 2 graphics architecture.[50] The GPU has 36 compute units running at a variable frequency capped at 2.23 GHz, making it capable of a peak theoretical performance of 10.28 teraFLOPS.[51][52][53] The GPU supports hardware-accelerated real-time ray tracing, a rendering technique that allows for realistic lighting and reflections.[17] It is programmed via Sony’s new AGC graphics API.[54][55] The console has 16 GB of GDDR6 SDRAM with a peak bandwidth of 448 GB/s,[49] and integrates Bluetooth 5.1, and 802.11ax (Wi-Fi 6).[56]

    Both the CPU and GPU are monitored by a special boost system incorporating AMD’s SmartShift technology that adjusts the frequency of these units based on the current activities of both to target ideal constant power drawn and a model SoC performance profile.[57][58] For example, if the CPU is running at lower activity, the boost system may reduce its frequency and increase the frequency of the GPU for higher performance without otherwise affecting power use or cooling.[49]

    The cooling system includes a double-sided cooling fan for air intake that is 120 mm in diameter and 45 mm thick, and a large heat sink with a standard heat pipe design that Sony says has a “shape and airflow [which] make it possible to achieve the same performance as a vapor chamber“. SoC cooling includes a liquid metal thermal conductor which sits between the SoC and the heat sink.[59][60][61][62] The system contains a 350-watt power supply.[59][60][61] Sony developed the PlayStation 5 to consume less energy than the PlayStation 4 for suspended gameplay states.[63]

    The console has a new audio technology called Tempest Engine, allowing hundreds of simultaneous sound sources compared to 50 for the PlayStation 4.[49]

    Storage architecture

    The internal storage of the PlayStation 5 is a custom-built 825 GB solid-state drive (667 GB available)[64] with a 12-channel interface, achieving a raw throughput of 5.5 GB/s. This atypical drive size was found to be optimal for the 12-channel pathway rather than a more common 512 GB or 1 TB unit. With a dedicated decompression unit supporting zlib and the new Oodle Kraken data compression protocol from RAD Game Tools, the unit has a typical throughput of 8–9 GB/s.[49] Mark Cerny stated that a fast SSD was the top request from game developers so the goal not only was to have a theoretical raw read speed 100 times faster than PS4, but to eliminate input/output (I/O) bottleneck points so the performance target could be made effective. To this end, Sony designed a custom chip with multiple coprocessors to work in unison with the flash memory controller to reduce latency and channel data more efficiently around the system. At peak, the custom unit is capable of processing up to 22 GB/s of compressible data.[65]

    Storage for games is expandable up to an additional 8TB through a single internal NVM Express (NVMe) M.2 solid-state drive, and up to an additional 8TB through an external USB hard drive or SSD.[49][66] Initially at launch, NVMe drives were not supported and the console would not boot if one was installed.[67] Beta system software support for the M.2 port was released in July 2021,[68] while full support was added in a September 2021 system update.[69] The internal SSD is not user-serviceable, since its flash memory chips and controller are built into the PlayStation 5’s motherboard.[70] Though game installation is mandatory, the user has some control of what to install such as only installing the multiplayer component of a game.[71] While PlayStation 4 games can be moved between the internal SSD and an external USB or M.2 drive to free up space on the SSD, PlayStation 5 games must be stored on the internal SSD or external M.2 drive to be played, and at launch could not be moved to an external storage device.[72] An April 2021 system patch enabled users to move PlayStation 5 games to and from an external USB storage device, though the games must still reside on the internal SSD to be played.[73]

    The base version of the PlayStation 5 includes an Ultra HD Blu-ray optical drive[49] compatible with Ultra HD Blu-ray discs, standard Blu-ray discs and DVDs. The PlayStation 5 does not support CDs and will not play 3D Blu-ray content.[74][75] The choice of Ultra-HD Blu-ray as the disc medium means PlayStation 5 game discs can hold up to 100 GB of data, in contrast to PlayStation 4 games which usually came on dual-layer standard Blu-ray discs capable of holding up to 50 GB.[76] An example of this is the title Gran Turismo 7. The PS4 version comes on 2 discs whereas the PS5 version comes on one.[77]

    Form factor

    The console’s form factor was revealed during the June 11, 2020, presentation.[40] Sony President Jim Ryan stated that the aesthetics are intended to be “transformational in how they look, sound, and feel”.[78] The launch unit is a two-tone design matching the design of the DualSense controller, with a black internal block flanked by two white wings along its sides, each lit by blue LEDs. Ryan stated that more colors than white and black may be available after launch.[78] The unit can operate vertically or horizontally. Two long air intake vents run along the front, and heat exhaust vents dominate the rear.[59][60][61] The wings are removable to access certain internal components such as the PCIe 4.0 NVMe SSD storage expansion slot, the power supply, and the optional Blu-ray disc drive.[59][60][61] Beneath the side panels are two “dust catchers” – holes allowing the user to vacuum out dust collected by the cooling system.[59][60][61] Senior Art Director Yujin Morisawa led the console’s case design, inspired by the term “five dimensions” and crafting the skeleton of its design around circles and squares that would make players comfortable when looking at it. Morisawa also had to manage the case shape to provide enough internal volume within the unit for all the technical hardware while reducing its size without restricting airflow.[79]

    The Blu-ray version has dimensions of 390 by 260 by 104 millimeters (15.4 in × 10.2 in × 4.1 in) and 4.5 kilograms (9.9 lb), and the download-only version is slightly slimmer, at 390 by 260 by 92 millimeters (15.4 in × 10.2 in × 3.6 in) and 3.9 kilograms (8.6 lb).[80] The console has been recognized for its large size in comparison to previous gaming consoles, and its size has been attributed to ensuring effective cooling management and minimizing noise during operation.[81][82][83]

    The front includes a USB-C port with USB 3.1 Gen 2 and a USB-A port with USB 2.0. The back has two USB-A ports with USB 3.1 Gen 2, an HDMI 2.1 port, Gigabit Ethernet, and power.[40][84][85]

    DualSense and DualSense Edge controllers

    Main article: DualShock § DualSense

    The DualSense controller

    The DualSense Edge controller

    The DualSense wireless controller for the PlayStation 5 was revealed on April 7, 2020.[86] It is based on the prior DualShock controller but with modifications influenced by discussions with game designers and players.[86] The DualSense controller has adaptive triggers with force feedback through voice coil actuators that can change the resistance to the player as necessary, supporting experiences such as virtually drawing an arrow from a bow.[71] The DualSense maintains the same buttons as the DualShock 4, though the “Share” button was renamed to “Create” with additional means for players to create and share content. A new built-in microphone array was added so players can speak to others using only the controller,[86] and the included controller speaker has been improved.[71] It has two-tone coloring, primarily white with black facing, with the black piece being easily detachable.[87] The light bar has been moved to the sides of the touchpad.[86] It has USB-C connectivity, a higher-rated battery, and an audio jack.[71][88] As an Easter egg, the texture of the controller unit is covered in miniature versions of the four PlayStation button symbols (cross, circle, square, and triangle).[79]

    Sony revealed the DualSense Edge (CFI-ZCP1), a new controller for the PlayStation 5 featuring additional capabilities, in August 2022.[89] The controller features a more modular design than the DualSense with replaceable stick modules, multiple control profiles and an option of relocating map inputs.[89] The controller was initially released on January 26, 2023, on PlayStation Direct, but was made available through other retailers on February 23, 2023.[90]

    Hardware revisions

    Standard Model

    Sony began shipping a minor hardware revision of the PlayStation 5 in August 2021. The new design (the 1100 series), reduced the size and weight of the heat sink, reducing the net system weight by 300 grams (0.66 lb), without having a noticeable effect on cooling performance, according to Digital Foundry and Gamers Nexus.[91] This design requires no screwdriver for the console stand.[92]

    In August 2022, Sony began shipping another hardware revision (the 1200 series), for both the base and digital versions of the PS5, which used a die shrink of the original SoC. This lowered the power draw of the SoC and Sony redesigned the heatsink again, contributing to a weight decrease.[93] The Digital Edition now weighs 3.4 kg (compared to 3.9 kg for the launch version) and the base version weighs 3.9 kg (compared to 4.5 kg for the launch version).[94]

    PlayStation 5 Slim

    New, slimmer models of the PS5 and PS5 Digital Edition, colloquially referred to as the PlayStation 5 Slim,[95][96][97] were announced by Sony in October 2023 for release in November 2023, replacing both original versions of the system. The two new models are smaller than the original PS5, have 1 TB of internal storage and replaces the front USB-A port with another USB-C port (albeit with USB 2.0 instead of USB 3.1 Gen 2). The drive-less Digital Edition’s cost was increased by US$50. A disc drive kit can be purchased for US$79 and installed onto the Digital Edition, making it functionally and visually the same as the base model.[98][99] Unlike the original disc model, the slim’s detachable disc drive requires an internet connection during initial setup.[100]

    PlayStation 5 Pro

    PS5 Pro with visible black “gills” on the sides

    The PlayStation 5 Pro (PS5 Pro) was formally announced by Sony on September 10, 2024,[101] following industry rumors since March 2024. Among other changes, the new console has three primary improvements: a GPU about 45% faster than that in the existing PlayStation 5, a deep learning-based image upscaling technology called PlayStation Spectral Super Resolution (PSSR), and twice as fast ray tracing performance compared to the PlayStation 5. As a result, games optimized for the Pro are expected to support 4K resolutions at 60 frames per second.[102] It also ships with 2 TB of internal SSD storage, but does not include an optical disc drive nor vertical stand, which can be purchased separately. The Pro unit also includes support for Wi-Fi 7 and 8K resolution output.[102][103] Games can be patched to access features of the Pro system, with 50 games expected to be ready with enhanced versions by the system launch.[102] Industry rumors stated that Sony’s internal studios had been working with the devkit version of the Pro console as early as September 2023.[104][105] A Game Boost feature would also allow selected PS4 games to have improved resolutions on the Pro system, with about 8,500 such games set to use this feature at launch.[102] The Pro model was released globally on November 7, 2024, with a price point of US$699 / £699 / €799.[101][106]

    The pricing of the PS5 Pro made it one of the most expensive consoles to be released with accounting for inflation, and the second most-expensive within the PlayStation line following the original PlayStation 3 price of $499+.[107] Rolling Stone observed an “overwhelmingly negative” response to the console’s limited increase of benefits.[108] Sports Illustrated mocked the price point, with editor Dave Aubrey writing: “It feels almost cruel, in a climate like this, to try and convince people that the PS5 Pro, with its meager enhancements, is actually worth the money.”[109] Sony president Hiroki Totoki stated in an investor call in November 2024 that the company did not believe the high price had a negative impact on sales, since the Pro model was targeting hardcore users who are willing to pay more for high performance.[110]

    30th anniversary editions

    Limited quantities of the PS5 Digital Edition and PS5 Pro, with gray cases and special branding, were released on November 21, 2024, to celebrate the brand’s 30th anniversary. Similar branded PlayStation DualSense, DualSense Edge, and PlayStation Portal devices were also made available.[111]

    Additional accessories

    Accessories include a charging station for the DualSense, a new HD camera, and a media remote control. The Pulse 3D wireless headset is integrated with the PS5’s Tempest Engine 3D audio technology.[40] The PS5 is backwards compatible with most existing PS4 controllers and accessories for PS4 games only – some with limited functionality. Rock Band peripherals are supported since Rock Band 2.[112] PS5 games can use the existing PlayStation MovePlayStation CameraPlayStation VR Aim Controller, officially licensed headsets, and specialty controllers with official licenses like flight sticks and racing wheels.[113]

    PlayStation VR2

    Main article: PlayStation VR2

    Sony announced the PlayStation VR2 for the PlayStation 5 in January 2022.[114][115][116][117] A successor to the PlayStation VR, the device consists of a headset featuring dual OLED panels capable of 4K resolution, HDR and 90/120 Hz refresh rates. It also includes two Sense controllers which have 14 embedded IR LEDs for tracking, and haptic feedback and adaptive triggers, similar to the DualSense controller included with the PlayStation 5. The headset features eye-tracking for foveated rendering and in-game features in select games. Additionally, the controllers includes finger touch detection, used to render the position of the thumb, index and middle fingers to show on in-game models. Unlike its predecessor, it does not require external cameras for it positioning; instead, it uses four cameras inside the headset to track the headset and controller’s position, using only the headset’s USB-C cable to connect to the console.[118]

    The headset launched on February 22, 2023, for $549.99 in the United States, €599.99 in the EU, and £529.99 in the United Kingdom. Games available for the PS VR2 at launch included Horizon Call of the MountainGran Turismo 7, and Resident Evil Village. The headset is not compatible with games released for the previous generation PS VR by default, requiring developers to update their games. The PlayStation VR2 released to positive reviews, but was later criticized for a lack of continued support.[119][120][121]

    System software

    The PlayStation 5 home screen

    The PlayStation 5’s user interface is characterized by Sony as “accessible and informative”, providing updates of friends’ activities, available multiplayer activities, and single-player missions and rewards. Cerny stated “we don’t want the player to have to boot the game, see what’s up, boot the game, see what’s up”, so all of these options are “visible in the UI”.[14] Matt MacLaurin, the current vice president of UX design at PlayStation, described the redesigned user interface as a “very interesting evolution of the OS”, and a “100 percent overhaul of the PS4 UI and some very different new concepts”.[122] MacLaurin stated that the UI is extremely fast with a new and robust visual language.[123]

    Eurogamer said the user interface was conceived for responsiveness, improved accessibility, clarity, and simplicity.[124] It is rendered in 4K resolution and high dynamic range. Users are greeted with a stylistic boot-up animation and a new login screen. The central design concepts and motifs introduced on the PS4 were redesigned into a new home screen user interface. The top of the screen has a row of applications, and two upper tabs to switch between showing games or media apps. Selecting a game reveals individual activities such as a specific level or multiplayer mode. PlayStation Store is no longer a standalone application and is now fully integrated into the home screen user interface.[125]

    The most significant departure from the PS4 interface is the introduction of the Control Center, accessed from the bottom of the screen by pressing the PS button. The Control Center is divided into two sections. The upper portion is a row of cards suggesting actions based on the current game or recent actions such as a group chat. Game-related cards may present players with gameplay information such as a progress report toward completing specific missions, or listing game challenges with an option to jump directly to them. PlayStation Plus subscribers see game activity cards with hints, tips, screenshots, or videos detailing how to complete the activity. System-level items may present the player with options such as PlayStation Store sale information, or recent screenshots taken by the user to be shared. These features are available for PS5 games or for updated PS4 games. The lower portion of the Control Center contains a customizable horizontal row of icons, including notifications, status updates, friends list, and system settings.[126] According to internal materials reviewed by Vice, the strategy behind this “activities”-focused UI was to help players in committing time towards games particularly single-player video games which Sony felt were thriving on the PlayStation console environment. Sony recognized that at present, many players did not have as much time to commit to playing games, so the notion of activity cards was used to help give players an idea of what activities they could do in a game and how long it would take so that they could work that activity into their schedule.[127]

    The PlayStation 5 supports multiple streaming services such as Netflix and YouTube, with support for others hinted at in the future.[128][129][130] Sony Pictures Core service was released on the system in 2023. The system included support for PlayStation Now, Sony’s subscription-based cloud gaming service, while it was available.[131] Sony’s Remote Play application, available on the PlayStation 4, WindowsiOS, and Android devices, was updated just prior to the PlayStation 5’s launch to allow a user to remotely play their PlayStation 5 games on these other devices over a local network.[132]

    Software updates

    In April 2021, Sony released a new software update through which users can transfer their downloaded PS5 game to an external USB hard drive.[133] Sony announced a PlayStation 5 system software beta program in June 2021, similar to the Xbox Insider program, where signed-up users can receive early releases of planned updates to the console’s software for testing prior to their release.[134] One of the first major features offered in this program was support for expanding internal storage via the M.2 port, added in the beta software path in July 2021.[68]

    In September 2021, Sony released a new software update offering support for a new trophy tracker, Control Center customization, 3D audio support for built-in TV speakers, internal SSD expansion and several UX enhancements.[135] Sony introduced Game Trials in October 2021, starting with a limited release for UK users for Death Stranding: Director’s Cut and Sackboy: A Big Adventure. Users have access to download and play the full version of the game for a fixed amount of time through these Game Trials, after which they would be required to buy the game to continue playing.[136]

    In March 2022, Sony released software update 5.00 which adds several improvements for accessibility such as an improved screen reader with support for features like mono audio, reading notifications aloud, additional language support, and the ability to show a check mark on enabled settings. Support for voice commands was also introduced in this update for users in the United States and United Kingdom, which allows users to control their PlayStation 5 by saying “Hey, PlayStation” and then a chosen command. Support for the Ukrainian language was also added, and Game Base was enhanced with the abilities to view all friends in a new “Friends” tab, more easily decline friend requests, and other enhancements and updates. There were also various enhancements made to trophies, child accounts, the home screen, and other features.[137]

    On March 8, 2023, Sony released software update 7.00, which included VRR support for 1440p resolution, the ability to transfer data between PS5 consoles, support for voice chat on Discord, and support for using voice to save video clips of gameplay (at release, this is only available in English for the US and UK).[138]

    On September 13, 2023, Sony released software update 8.00, which included support for Dolby Atmos, the possibility to use an M.2 SSD with a maximum capacity of 8 TB (up from the previous 4 TB limit), and the ability to mute the start-up beep sound.[139]

    On March 13, 2024, Sony released software update 9.00, which included the ability to adjust the brightness of the PS5’s power indicator, added new features in Parties and Share Screen, and improved the DualSense and DualSense Edge wireless controllers mic input quality with a new AI machine-learning model.[140]

    On September 12, 2024, Sony released software update 10.00, which added Welcome hub, Party Share, personalized 3D audio profiles, adaptive controller charging, and support for enabling remote play for individual users.[141]

    Games

    Main article: List of PlayStation 5 games

    Each PlayStation 5 console comes preinstalled with Astro’s Playroom, a game designed to serve as a demonstration of the DualSense controller.[142] Games are not region locked, so games purchased in one region can be played on consoles in all regions.[131]

    Sony announced its concurrent responsibilities of supporting the PlayStation 4 community, and embracing the PlayStation 5 as a major technological advancement. In an interview with GamesIndustry.biz, Ryan stated “We have always said that we believe in generations. We believe that when you go to all the trouble of creating a next-gen console, that it should include features and benefits that the previous generation does not include. And that, in our view, people should make games that can make the most of those features.”[143] Discussing the capabilities of the DualSense controller with Geoff Keighley, General manager Eric Lempel affirmed that Sony “want[s] to evolve every part of the experience”, but for that to happen “we can’t take everybody with us from previous consoles into [a next-generation experience]. You need new hardware, you need new devices to experience what these developers want you to experience.”[144][145] Ratchet & Clank: Rift Apart was highlighted as a next-generation game that is not technically possible on older hardware. Lempel assured Keighley that interest in PlayStation 4 will not end abruptly, with more to come.[144]

    Sony’s definition of consoles as distinct generations had been widely interpreted as an era-defining shift to PS5-exclusive games that exploit the console’s capabilities instead of releasing cross-generation games that play across both PlayStation consoles. Ryan said that there should be no disappointment as the PS5 versions take advantage of the console’s advanced feature set and initially planned that PS4 versions can be freely upgraded. Few major games such as Horizon Forbidden West are developed as concurrent releases for PS5 and PS4,[146] and Sony supports any publisher that wants to offer enhanced versions of PS4 games at no additional cost.[147][148][149][150][151] However, in May 2021, Sony announced a major shift in this approach, with previously PS5-exclusive games Gran Turismo 7 and God of War Ragnarök now planned as both PS5 and PS4 games. Game journalists believed this was a factor related to the effect of the global semiconductor shortage from the COVID-19 pandemic on PlayStation 5 availability.[152] Sony initially had planned to charge PS4 users to upgrade to the PS5 version of Horizon Forbidden West when preorders were announced, but after negative feedback from consumers (who pointed out that Sony had previously mentioned that Horizon Forbidden West would have a free upgrade), stated that this upgrade will be free, but all future PS4 to PS5 upgrades from their first-party games will be at cost, reversing course from their earlier plans.[153]

    Eurogamer reported that Sony’s certification program as of May 2020 required PS4 games, submitted for certification after July 13, 2020, to be natively compatible with the PlayStation 5.[154]

    Backward compatibility

    According to Hideaki Nishino, Sony’s senior vice president of Platform Planning and Management, the PS5 is designed to be backward compatible with more than “99 percent” of PS4’s 4,000+ game library, playable from launch day.[155] The console is compatible with PlayStation VR.[14] Because of PS5’s high-speed SSD and increased processing power, many PS4 games gain from improved loading times or gameplay speeds “so that they can benefit from higher or more stable frame rates and potentially higher resolutions”.[21][156] Players can synchronize their saved game files through cloud storage or transfer them using a USB storage device so no progress is lost.[155] Backward compatibility is enabled in part by the similarity of hardware architecture, such as “extra logic” in the RDNA 2 GPU that ensures compatibility with PS4’s GCN-based GPU.[14][23] Mark Cerny explained during a March 2020 presentation and later in an interview with Digital Foundry how CPU clock timing required particular attention; though the Zen 2 CPU has an instruction set to handle the PS4’s Jaguar CPU, their timings can be very different, so Sony worked closely with AMD when developing the Zen 2 CPU to more closely match the Jaguar’s timings.[20] PS5 backward compatibility may exhibit errors with some PS4 games,[157] and does not include previous generations. However, some older PlayStation console games are available through the PlayStation Plus game streaming service which is available for the PlayStation 5.[158][159] The PlayStation 4’s Share menu cannot be displayed but the PS5’s Create menu can be used to capture screenshots or video.[157]

    All compatible downloaded versions of PS4 games are visible in the library on the PS5 and available for download. The games can also be copied via USB hard drive or Wi-Fi. Save data can be copied in the same way or via the cloud storage.[160] On October 9, 2020, Sony released a list of ten PS4 games identified as being incompatible with PS5; the list has shortened since as some developers released compatibility updates for previously incompatible games.[161] As of December 16, 2021, the official PlayStation website shows six PS4 games that remain incompatible with PS5; Afro Samurai 2: Revenge of Kuma Volume OneHitman Go: Definitive EditionJust Deal With It!Robinson: The JourneyShadwen, and We Sing.[162]

    Reception

    The PlayStation 5 was generally well received at launch, with much praise of its DualSense controller’s improved haptic feedback and adaptive triggers.[163] Astro’s Playroom, which comes preinstalled on every PS5 and is designed to demonstrate the controller’s features, was praised with Laptop Mag calling it “deceptively cute”.[164] The exclusive line-up, including Spider-Man: Miles Morales and Demon’s Souls, was heavily praised, although some reviewers, such as TechRadar, said there should have been more launch games.[165] The console’s user interface was generally praised for being fast and easy to navigate.[166]

    Many reviewers found the console’s design polarizing. CNET described the black and white scheme as “clearly meant to be a sculptural conversation piece”. The large size was criticized by Tom’s Guide as “inelegant”,[167] and by others as frustrating its integration into a home entertainment center.[168] Many also acknowledged the size for improving the cooling and quieting of its operation.[166][169] The comparatively small 667 GB of usable SSD space was criticized.[168]

    More technical reviews, such as those by Digital Foundry, noted that features such as variable refresh rate and the advertised 8K video output mode were not present at launch. They lauded the ray tracing, SSD speed, and 120 Hz output capabilities.[169]

    Sales

    The PlayStation 5, as with the Xbox Series X/S, was in limited supply immediately upon launch,[170] and through 2021 due to a global semiconductor shortage,[171][172] combined with increased demand for video game consoles due to the COVID-19 pandemic.[173] Sony expected supply to continue to be limited until at least 2022.[174] Scalpers took advantage of the shortage, attempting to sell the console for thousands of dollars.[175] Sony expanded its PlayStation Direct program to sell consoles directly to consumers within Europe in November 2021 to bypass scalpers.[176][177]

    Two weeks after launch, Sony declared the largest launch in PlayStation history, surpassing the PlayStation 4’s 2.1 million units in its first two weeks in 2013.[178] During the system’s first week of release in Japan, 103,901 standard consoles were sold, and 14,181 Digital Editions were sold, for a combined total of 118,082, making it the best-selling console in the country for that week.[179] By September 2021, Sony reported over a million PS5 sales in Japan. In comparison, its predecessor did not reach a million units sold until a year after release.[180] In the UK, the PS5 was the best-selling video game console sold in the month of November.[181] In Spain, the PS5 sold over 43,000 units in the first week of release.[182]

    Sony reported total shipments of the PS5 through its fiscal quarter ending December 31, 2020 of 4.5 million units, which were similar numbers to the PS4’s launch shipments.[183][184] Total shipments of PlayStation 5 reached 7.8 million by March 31, 2021, surpassing the 7.6 million units that the PS4 had shipped in its first two-quarters of release.[185] Sony reported that as of July 18, 2021, 10 million PS5 units had been sold through, making the PS5 its fastest-selling console to date.[186][187] The company later confirmed that by June 30, 2021, it had shipped 10.1 million consoles, indicating that nearly every shipped console had been sold as soon as it reached the market.[188] Console shipments surpassed 13.4 million as of September 30, 2021.[189] The company anticipated in August that it would have enough stock hardware to ship more than 22 million PS5 units by the end of its 2021 fiscal year in March 2022,[190] but this was revised to 15 million units in November. Despite this, sales during the fiscal year 2022 were forecast to increase to 22.6 million units.[191] Bloomberg News reported in January 2022 that Sony was continuing production of the PS4 rather than discontinue it at the end of 2021, in order to help alleviate the shortage of the PS5 while the chip shortage continued.[192] By the end of September 2024, total shipments of PS5 units had reached 65 million units.[193]

    Sales of the PS5 reached 20 million units by May 2022,[194] 40 million units by July 2023,[195] 50 million units by December 2023,[196] and 75 million units by February 2025

  • Racing flags

    Racing flags[1] are traditionally used in auto racing and similar motorsports to indicate track conditions and to communicate important messages to drivers. Typically, the starter, sometimes the grand marshal of a race, waves the flags atop a flag stand near the start-finish line. Track marshals are also stationed at observation posts along the race track in order to communicate both local and course-wide conditions to drivers. Alternatively, some race tracks employ lights to supplement the primary flag at the start-finish line.

    Summary

    [edit]

    While there is no universal system of racing flags across all of motorsports, most series have standardized them, with some flags carrying over between series. For example, the chequered flag is commonly used across all of motorsport to signify the end of a session (practice, qualifying, or race), while the penalty flags differ from series to series. FIA-sanctioned championship flags are the most commonly used internationally as they cover championships such as Formula 1, the FIA World Endurance Championship and WTCC, and are adopted (and sometimes adapted) by many more motorsport governing bodies across the world such as, for example, the MSA.

    Status flags

    [edit]

    Status flags are used to inform all drivers of the general status of the course during a race. In addition, the green, yellow, and red flags described below may be augmented or replaced by lights at various points around the circuit.

    Green flag

    [edit]

    The green flag signals a clear track to race on and the start of the race

    The solid green flag is usually displayed by the starter to indicate the start of a race. During a race, it is displayed at the end of a caution period or a temporary delay to indicate that the race is restarting. The waving of a green flag is almost universally supplemented with the illumination of green lights (resembling traffic lights) at various intervals around the course, particularly on ovals.

    If the race is not under caution or delayed, it is said to be “under green-flag conditions”. However, the flag itself is typically not continuously waved by the starter. No flag displayed at the starter’s stand implies safe, green-flag conditions. At all times, however, the green lights remain lit.

    • When shown at a marshalling post, a green flag may indicate the end of a local yellow-flag zone.[2]
    • A separate green flag displayed at the entrance to the pit area indicate that the pits are open.[2]
    • In NASCAR, a green and yellow flag waved at the same time indicates that the race is being started or restarted under caution and laps are being counted. This is sometimes called a “running yellow” and usually occurs when a track is drying after a rain delay. The officials will utilize the cars in the field to facilitate the final drying of the course, but in order to not waste fuel (affecting fuel strategy, etc.), and delay the race further, the laps are counted towards the advertised race distance.[6]
    • In 1980, USAC flagman Duane Sweeney started a tradition at the Indianapolis 500 of waving twin green flags for added visual effect at the start of the race. Green flags waved at restarts were single.[9]
    • Since around the 1990s, some races on occasion invite celebrity guests to wave the green flag at the start of the race.
    • Before the use of starting lights in Formula One and most other FIA sanctioned or associated events, the national flag of the country in which a race is occurring, instead of a green flag, was used to signal its start. This practice is retained on occasion in the event of equipment failure, or simply as a tradition, such as at the 24 Hours of Le Mans.
    • In some series, the green flag is waved at the rear of the grid following the formation lap to indicate to the official controlling the race start that the final car has reached its starting position and the race can be started.

    Yellow flag

    [edit]

    The yellow flag means caution

    The solid yellow flag, or caution flag, universally requires drivers to slow down due to a hazard on the track, typically a crash, a stopped car, debris or light rain. However, the procedures for displaying the yellow flag vary for different racing styles and sanctioning bodies.

    In Formula One racing, a yellow flag displayed at the starter’s stand or a marshal station indicates that there is a hazard “downstream” of the station. The manner of display depends on the location of the hazard:

    • A single waved flag denotes a hazard on the racing surface itself.
    • A single stationary flag denotes a hazard near the racing surface.
    • Two flags waved simultaneously denotes a hazard that wholly or partly blocks the racing surface (like an accident). This informs the driver that there may be marshals on the track and to prepare to stop, if necessary.[2]

    When shown at a station, drivers are forbidden from overtaking until either the hazard or the next flag station displaying a green flag (signifying the end of a cautionary section) is passed. This flag is shown at the discretion of the marshals manning the station.[2]

    A yellow flag with SC (safety car) sign is shown during the 2006 United States Grand Prix

    When the safety car is on the circuit, all flag points will display a “safety car board” (a large white board with “SC” in large black lettering). When flag points are under radio control, this will happen immediately, otherwise, the board is displayed when the safety car comes round for the first time. This is accompanied by a waved yellow flag. Standard yellow flag conditions apply to the whole circuit; notably, overtaking is completely forbidden. When the safety car comes in and the race resumes, a green flag is displayed at the start line, and subsequently at all flag points around the circuit for one lap. Overtaking is not allowed until the cars have passed the start/finish line.[2]

    When there are circumstances where double-waved yellow flags are needed yet usage of the safety car is not warranted, then the race will be under a virtual safety car period, during which all flag points will display a “VSC board” and all light panels on track will display the letters VSC surrounded by a flashing yellow border. Under the VSC procedure, all drivers on the track must reduce their speed and stay above a minimum time set by race officials at least once in each marshalling sector. Overtaking is not permitted unless another driver enters the pit lane or if a car slows down due to an obvious problem. When deemed safe to end the VSC procedure, teams are notified via the official messaging system 10 to 15 seconds before green flags are waved.[10]

    Full-course yellow

    [edit]

    Most races in the FIA World Endurance Championship may be under a full-course yellow period upon discretion of the race director when deemed necessary for safety reasons. Once declared, all flag points will display an “FCY board” and all cars on track must immediately slow down to 80 km/h (50 mph) and maintain their distance to the cars in front and behind. Overtaking is forbidden until green flags are waved.[11]

    The FCY procedure was used during the 2019 24 Hours of Le Mans in response to Porsche’s dominant GTE-Pro victory in 2018. Partial track “slow zones” are identified by track-side horizontal markings at both beginning and end, and “next slow” boards in the preceding zone. Within the zone, all marshal posts will display double-waved yellow flags and “slow” boards, and all light panels display the letters SZ surrounded by a flashing yellow border. All cars within the zone must slow down to 80 km/h until they are clear of the waved green flag at the end.[12][13]

    In Formula E, the FCY condition is used, but unlike any other racing series, the cars have an FCY speed limiter. When activated, the cars will slow down to 50 km/h (31 mph). Overtaking under the FCY condition is not allowed, and could result in a penalty. This happened at the 2019 Rome ePrix, when Jean Eric Vergne overtook future Techeetah teammate António Félix da Costa. As a result, Vergne was given a five-second time penalty. For the 2019-20 Formula E season, activating attack mode during FCY was disallowed. Additionally, for every minute under FCY, 1kWh of energy gets taken out of their energy allocation.

    In both NASCAR and IndyCar, a single yellow flag waved from the starter’s stand places the race under caution. At this time, a pace car will enter the course and lead the field at a safe, predetermined, reduced speed. On oval tracks, yellow lights universally supplement the primary flag at the start-finish line. These lights usually operate in a flashing manner, in order to quickly gain the attention of the drivers. The field is locked into place at the onset of caution periods and no one is allowed to pass another car without mutual consent (excluding crashed and immobile cars). In some races, though, cars may pass one another on pit road during a caution period. When the starter shows a furled yellow flag, it indicates one lap to green.[6][5]

    On road course races in IndyCar, a single yellow flag at a marshaling station indicates a “local” yellow, similar to the aforementioned rules in Formula One. In these cases, the pace car does not enter the track, and the caution period is limited only to that particular segment of the track. Green flag racing prevails around the remainder of the course. Twin yellow flags displayed at the starter’s stand indicates a “full-course caution”, in which the pace car would enter the track and the entire course would be under caution. This might occur for a serious crash or other major hazards. NASCAR has also experimented with “local yellows” on their road course events, although a plain blue flag is used instead.[5]

    In the case of snowmobile racing, the yellow flag is displayed at or before the point of the hazard. When a snowmobile racer crosses the yellow flag, the race will continue, however, the skis and track of the snowmobile must remain on the ground.

    In snowmobile water cross (racing on open water), the caution flag simply warns the racers that one or more racers have sunk and are in the water, however the race will continue as normal.

    In horse racing, the yellow flag means that there is a serious incident ahead, the horses must be pulled up and the race must be declared void. Most yellow flags are seen when a horse has suffered a serious injury.

    Code 60 flag

    [edit]

    The pink flag orders drivers to slow down to 60 km/h (37 mph) and to not overtake until a green flag is waved

    As an alternative to the full-course yellow and safety car periods used during other FIA-backed races, the 24H Series uses a series of purple lights and flags to declare a “Code 60” period. Under “Code 60”, overtaking is not allowed and all drivers must slow their cars down to a maximum of 60 km/h (37 mph). The race resumes immediately when green flags are waved and green lights are flashing at each marshal post. Yellow flags are still used to indicate local cautions.[14]

    Safety concerns and the beneficiary in NASCAR

    [edit]

    The point at which the caution period starts is a topic of controversy in oval racing. Traditionally, the cars were locked into their positions when they crossed the start-finish line, but technological advancements have made it possible to lock them in at the instant that the caution is declared. This has effectively put an end to the “race back to the caution“, in which drivers speed up during yellow flag periods to beat the leader to the flag. This practice, while giving lapped drivers a better chance to make their lap back, was at times highly dangerous in that it encouraged drivers to engage in pitched battles with major safety hazards on track. Safety workers were not able to respond to accidents until the cars were under control of the pace car, which markedly slowed their response times to potentially injured drivers. To compensate for the elimination of the race back to the caution, NASCAR and some other motorsports series, both road racing and short oval, have implemented the free pass, which allows the highest-placed car that is a full lap or more behind the race leader to complete an extra lap during the caution period in order to make up a lap.

    In some series (Indy Racing League, Champ Car, beginning in 2007, Formula One, and beginning in mid 2009, NASCAR) lapped cars between the pace car and the leader are allowed to move to the rear of the next lap when the signal is given two laps before a restart.

    In Formula One, all lapped cars between the leaders are permitted to advance one lap.

    The rule, as enforced in the three open-wheel series, is designed to prevent lapped cars from blocking on ensuing restarts, as to prevent unsportsmanlike blocking when a lapped teammate or friend of one driver attempts to help that driver through impeding the progress of an opponent on the restart.

    Red and yellow striped flag

    [edit]

    The “surface flag” indicates a slippery track surface ahead

    The red and yellow striped flag or surface flag is displayed stationary at local flag stations to indicate that track conditions have changed due to substances on the track which could reduce grip or cause a car to lose control. Generally oil, coolant, small pieces of debris or sand are the hazards. Many organizations will display this flag for only two laps, after which the changed surface is considered to merely be part of the track. This flag is generally not used anymore; during conditions that would warrant this flag to be waved, the race enters virtual safety car.

    Red flag

    [edit]

    The red flag signals the suspension of the current session

    The solid red flag is displayed when conditions are too dangerous to continue the session. Depending on the series and the circumstances, the cars are typically directed to proceed immediately to pit road, or to stop at a specific spot on the track. In some severe cases the cars might be required to stop immediately where they are. During red flag conditions, repair work in the pits, the garage area, or on the track is typically prohibited, except in non-points paying races.

    There are numerous hazards that might cause a need to halt or prematurely end a session. Many hazards, such as rain, lightning, darkness, a blocked course (due to debris, water, or safety vehicles), a car on fire, a severely demolished car (where parts are dropped on the track, like the engine), a serious accident where a driver was seriously injured or killed (only if death is officially announced) or a multi-car crash (especially one that results in serious injuries, extensive time to clean up or one that results in damage to walls, fences or the surface itself which require repairs) might prompt series officials to call for the red flag.

    Some series use a red flag to temporarily stop a race nearing the end of a race after an accident or other incident to minimize the number of caution laps, even when the situation would not warrant a red flag at other points in the race. This is usually done when a collision requiring cleanup would otherwise extend the caution period to take longer than the amount of race laps available to finish the race, when a fuel spill occurs on the circuit, or to maximize safety team work. During such a red-flag period, cars are directed to stop in line at a specific point on the track, usually directly opposite to the incident. In Supercars, a race that is suspended after 75% of the laps have been completed may be declared complete at the race director’s discretion, such as happened in Supercars forerunner Bathurst 1000 race in 1992 when torrential rain led to numerous cars crashing off the track in laps 144 and 145 and race results were woundback two laps.

    The red flag may be used to indicate a pre-determined pause in the race, such as in NASCAR’s Budweiser Shootout or the Sprint All Star Race. In these cases, the cars are directed to the pit area where some may be worked on to the extent the race rules allow.

    • In the event of a bad start, the yellow and red flags may be displayed together, or a unique diagonally divided red and yellow flag can be displayed, to indicate a restart. Drivers will go back to their starting positions and line up for another start. This is rarely used where computer scoring is involved, and can create much confusion as the drivers attempt to get back in order.
    • In NASCAR, a practice session or a qualifying session is ended with the red and black flags waved together.

    White flag

    [edit]

    The white flag signals that a slow moving vehicle ahead in FIA-sanctioned races, or the start of the final lap in NASCAR and IndyCar

    In Formula One, the white flag is waved on the last corner and the pit straight at the end of free practice sessions on Friday and Saturday, indicating to drivers that there are drivers doing practice starts on the pit straight. Drivers are permitted to do one practice start at the end of each free practice session.

    In all championships which use the FIA International Sporting Code, as well as North American road racing, the white flag indicates the presence of an officials car such as ambulance, fire truck, jet dryer, etc. or a competitor moving at below normal speed in the section of track covered by the flag station. In IndyCar, a stationary white flag means they are moving above one-third racing speed while waving means they are moving below one-third racing speed.

    In most American forms of motorsports – including NASCAR, IndyCar, and North American motorcycle road racing[15] – a waved white flag displayed at the starter’s stand indicates the start of the final lap of the race.

    In MotoGP, a white flag is used to inform riders that they are allowed to change machine. The race direction has deemed that the track is wet enough to justify the change of bikes and the Grand Prix becomes a wet race, having originally been declared a “dry race” at the start.

    In some series, a white flag is shown from all flag stations on the first lap of a practice or qualifying session so competitors will know which stations are staffed.

    National flag

    [edit]

    Prior to the adoption of starting lights, the Supercars series and its forerunners used a green flag to start the race. Following the adoption of lights as the routine starting device, if the starting lights were unavailable a race was started by lowering the national flag of whichever country the race was held in.[7]

    Instruction flags

    [edit]

    Instruction flags are usually used to communicate with one driver at a time.

    Black flag

    [edit]

    The black flag indicates a driver is disqualified in an FIA-sanctioned race, or orders a driver to the pits in NASCAR and IndyCar

    The solid black flag is used to summon a driver to the pits. It is usually associated with a penalty imposed on the driver for disobeying the rules, but may also be used when a car is suffering a mechanical failure, leaking fluid, smoking excessively, exhibiting damage such as loose bodywork, loose hood, dragging bumper, or any other damage that could potentially become a hazard to the driver or other competitors. In some cases, the black flag may be used to call a driver to the pits when their radio is not working, though this is not common.[16]

    In FIA International-permitted series, the black flag means an immediate disqualification for the driver involved. The car number of the summoned driver is displayed on the finish line. Some sanctioning bodies wave the black flag at all observation posts simultaneously to order all drivers to clear the track after the starter waves the red flag, often in the case of a serious accident.

    In Supercars races, infringements such as exceeding the pit lane speed limit, violating a restart after a safety car period, or causing an accident will result in a drive through pit penalty that must be taken in reasonable time. Rarely, due to the short amount of time in which the driver has to complete the penalty, such a penalty may be rescinded such as in race 28 of the 2021 season when, upon receiving a penalty for passing before the control line after a safety car period, Shane van Gisbergen protested over his radio that the lead driver had suddenly reduced throttle forcing van Gisbergen to pass, and throttle telemetry supported this. The sudden 42% reduction in throttle itself could have led to a drive through penalty for race leader Anton de Pasquale, but the very wet conditions and possible loss of traction and safety issues were mitigating circumstances.[17]

    When the black flag is used for disciplinary reasons in most races in North America, a driver is required to return to pit lane for at minimum a drive-through penalty. In cases of damage, the car must return to the pits and team is given an opportunity make repairs and get the car up to an acceptable condition, after which time it may rejoin the race. In either case, a driver being black-flagged is given a short window (typically 3–5 laps) to adhere. If the driver fails to serve the black flag and return to the pits within the required window, officials will cease scoring of that car. In rare cases when a disciplinary black flag comes very near the end of the race, and the race finishes before the serving window closes, officials may simply issue an alternative penalty, such as a 1-lap penalty. This happened to Michael Andretti at the 1994 Indianapolis 500.

    A driver may be black-flagged for failing to maintain a reasonable minimum speed, even if no apparent damage or mechanical failure is present. If the driver still cannot maintain minimum speed in relation to the leaders after repairs, the driver may be required to park for the remainder of the race. For example, NASCAR requires that a driver run at or above 115 percent of the fastest lap time by any driver in the final practice. (This can be converted to an average speed-limit based on the length of the course, which for oval tracks will be close to the actual speed limit at any given time.) IndyCar has a 105 percent rule, most notably used when officials parked Jean Alesi and Simona de Silvestro during the 2012 Indianapolis 500.

    In the case of snowmobile racing, the black flag comes in three stages to disqualification; the first flag is a warning to a racer, the second flag is a one-lap penalty, and the third is disqualification. In order for a snowmobile racer to receive a black flag, the racer must make contact with intent to inconvenience another racer.

    Black flag with orange circle

    [edit]

    This flag is used in FIA-sanctioned races to order a damaged car to the pits for repairs

    A mechanical black flag is a black flag with an orange disc in its center which indicates that a vehicle is being summoned to the pits due to serious mechanical problems or loose bodywork that presents a risk to other competitors. At some road racing events, it is used to summon the vehicle to the pits to inform the driver of violation “maximum sound levels”. Also known as the “meatball” flag.[18]

    Per-bend black-white flag

    [edit]

    This flag is used to indicate unsportsmanlike conduct in FIA-sanctioned races

    A diagonally divided black-and-white flag is displayed with a car number to indicate a warning for unsportsmanlike conduct. This flag can be displayed if a car tries to intentionally drive another car off the course, or if a driver gets out of their car and initiates an altercation with another driver. For example, Charles Leclerc was shown this flag for “bad sportsmanship” while defending from Lewis Hamilton during the 2019 Italian Grand Prix.[19]

    The black and white diagonal flag can also mean a warning to a driver for exceeding track limits.[20] For example, in 2023 Austrian Grand Prix in Formula One which had multiple penalties handed out to drivers for exceeding track limits, the black and white flag was shown to drivers multiple times: on their third infringement the flag was shown,[21] and then on the fourth and subsequent infringements time penalties were given.[22]

    Some administrators (NASCAR and IndyCar) do not distinguish mechanical problems or unsportsmanlike conduct from rules violations and simply use the solid black flag for all violations.

    Black flag with white cross

    [edit]

    In NASCAR and IndyCar, this flag indicates a driver is disqualified

    Some leagues use a black flag with a white saltire. This is displayed with a car number if a driver ignores the other black flags for an extended period and also it indicates that that car is no longer being scored. In NASCAR, the car is not scored again until it pays attention to the black flag by pitting once this flag is displayed. However, in IndyCar, they are no longer scored indefinitely (disqualified).

    Ignoring the black flag or the black-white cross flag intentionally may result in post-race disciplinary action in addition to disqualification from the race. Fines, probation, suspensions, and other penalties (e.g., points being docked from championship standings) may result, depending upon the severity of the situation.

    Blue flag

    [edit]

    In NASCAR and IndyCar, this flag orders backmarkers to give way to faster cars.

    A light blue flag, sometimes with a diagonal yellow, orange, or red stripe, informs a driver that a faster car is approaching and that the driver should move aside to allow one or more faster cars to pass. During a race, this would only be usually shown to a driver who is getting lapped but during practice or qualifying sessions, it could be shown to any driver. In most series, the blue flag is not mandatory—drivers obey it only as a courtesy to their fellow racers. As such, it is often referred to as the “courtesy flag”. In other series, drivers get severely penalized for not yielding or for interfering with the leaders, including getting sent to the pits for the rest of the race. In Formula One, if the driver about to be lapped ignores three waved blue flags in a row, he is required to serve a drive-through penalty. The blue flag may also be used to warn a driver that another car on the same lap is going to attempt to overtake them.

    The steady blue flag is displayed when a faster car is approaching, the blue flag is waved when the faster car is about to overtake.

    Not all racing series use blue flags, for example they are not used in rally or rallycross.

    In Formula One, blue lights or flags may be shown at the end of pit lanes to warn of approaching cars on the track.

    Chequered flag

    [edit]

    “Checkered flag” and “Chequered flag” redirect here. For other uses, see Checkered flag (disambiguation).

    “Finish flag” redirects here; not to be confused with Finnish flag.

    A typical chequered flag design

    The chequered flag (or checkered flag) is displayed at the start-finish line to indicate that the race is officially finished. At some circuits, the first flag point will display a repeat chequered flag (usually on the opposite side of the circuit). The flag is commonly associated with the winner of a race, as they are the first driver to “take” (in other words, drive past) the chequered flag.

    Upon seeing the chequered flag and crossing the finish line, drivers are required to slow to a safe speed, and return to their garage, parc fermé, or paddock, depending on the applicable regulations of the series.

    Design of the chequered flag

    [edit]

    There is no standard design for the chequered flag. Although it nearly always consists of alternating black and white squares or rectangles arranged in a chequerboard pattern, the number, size, and length-width proportions of the rectangles vary from one flag to another. Also, the chequered flag typically has a black rectangle at the corner of the flag closest to the top of the flagpole. There have been instances of the black and white squares being painted onto a wooden board and simply held up for drivers to observe at the finish line. Sometimes a sponsor’s logo is emblazoned in the center of the chequered flag. In NASCAR and F1 events, a single chequered flag is waved to signal the completion of a race. In IndyCar, two chequered flags are waved together, a tradition dating to the 1980 Indianapolis 500, but only if the race is under green conditions. (The starter will wave both a chequered and yellow flag if safety car conditions occur at the end of the race, in a yellow-chequer finish.)

    NASCAR green and white checkered flag for stages

    NASCAR traditionally has a special version of the chequered flag sewn for Victory Lane that has the name and date of the race on it, a practice that has spread to IndyCar. That flag is used for the team in the winner’s photographs taken after the race, and is a prize awarded to the team along with the race trophy. Teams often hang such flags at their headquarters in a similar fashion to other sports teams hanging championship banners from the rafters at stadiums.

    Beginning in the 2017 season, NASCAR has utilized a white-and-green variant of the chequered flag to indicate the end of a stage of a race. After the flag is waved, the race temporarily goes into caution to allow drivers who have had placed in the top 10 position following a stage to go into the pit road in a timely manner.

    Origins of the chequered flag

    [edit]

    The chequered flag originated in at the Glidden Tours, a road rally, in 1906.[23] Sidney Walden divided the courses into sections; the time check at the end of each section was performed by race officials called “checkers”.[23] These checkers used chequered flags to identify themselves.[23] The earliest known photographic record of a chequered flag being used to end a race was from the 1906 Vanderbilt Cup race held in Long Island, New York.[24]

    There is a persistent urban legend claiming that the flag originated in horse racing, but there is no basis for this myth.[25] Another myth claims that the chequered flag’s earliest known use was for 19th century bicycle races in France, but this claim also has no evidence.[26]

    In 1980, USAC starter Duane Sweeney started a tradition at the Indianapolis 500 by waving twin chequered flags at the end of the race. Previous starters had only used a single flag. Sweeney also marked the first use of twin green flags at the start of the race.[27][28]

    Celebrating a win with the chequered flag

    [edit]

    In snowmobile skipping, the chequered flag is attached to the racer’s life vest, and the racer is rewarded with a victory lap.

    At many short tracks, the flagman gives the chequered flag to the winner of the race, but a variety of other celebratory traditions, such as the burnout, the Polish victory lap and the victory lane or victory circle celebration, sometimes overshadow the chequered flag tradition.

    Use outside auto racing

    [edit]

    The chequered flag has become so well recognized that it is often used to indicate the conclusion of many things unrelated to auto racing. For example, some software installation programs display a chequered flag to indicate that a computer program has been installed successfully. [citation needed]

    Chequered flags were also posted at each corner of the end zones in the original Yankee Stadium when the facility was used by the New York Giants of the National Football League from 1956 through 1973.

    The chequered flag is not only used for auto racing, but also for a representation of the automotive industry itself.

    Flags in motorcycle racing

    The chequered, red, yellow, white, and green flags are used identically to how they are used in auto racing. The yellow and red striped flag is used to indicate debris on the track. Other flags used include:

    • A white flag with couped red cross, to indicate medical attention is required near the marshalling post. Can also mean an ambulance is on the course (generally a red cross is followed by the race being “red flagged”)
    • A white flag with a saltire red cross indicates precipitation and is used instead of the yellow-red striped slippery surface flag in rain conditions only.
    • A black flag with white border, indicating that a rider must leave the course.
    • A dark, rather than light blue flag, indicating that a faster motorcycle is approaching.
    • A white flag with a black “V”, to indicate poor visibility ahead. Used at the Isle of Man TT festival.
    • A white flag with a black ‘SUN’, to indicate glare from the sun ahead. Used at the Isle of Man TT festival.

    Practicality of racing flags

    [edit]

    Historically, the only means for race officials to communicate to drivers was through the usage of flags. With the advent of two-way or full-duplex radios, this is not necessarily the case. Most drivers racing on paved short track oval courses do not rely on flags; rather, they are informed of track conditions by their crew chiefs and spotters or by yellow and red flashing lights found on most oval tracks. Occasionally, though, some drivers must rely on the use of flags for information when they experience radio malfunctions. Flags are still used to tell the crowd of spectators what is happening. Dirt track and lower-level racers are less likely to have radios than their paved track counterparts.

    In contrast to smaller circuits, road racing drivers rely heavily on the use of flags. As it is impractical to have spotters covering all segments of a winding race track, the first indication to drivers of local hazards almost always comes from marshals stationed at various flag stations around the course. Missing or disregarding a flag can have critical consequences, as Mario and Michael Andretti discovered during a 1991 CART race in Detroit, Michigan. Michael came around a blind corner at high speed, without heeding the yellow flag being displayed—and plowed into the back of a CART safety truck tending to another disabled car. Fifteen seconds later, his father Mario disregarded the same madly waving yellows and crashed into the car the safety vehicle was trying to assist.[29]

    Modern F1 cars and other high-end formula racing cars have information displays on their steering wheels which can flash up the word flag to warn drivers when they are entering a sector with a local yellow. Most new circuits and older ones used for F1 employ trackside flashing lights at regular intervals, as a clearer way to signal yellow, green, red, blue or SC flag status to drivers than relying on them to spot a marshal waving a flag, especially so on modern circuits where there are large run-off areas which put the marshals well away from the actual track.
