What does each F1 flag mean? Guide to all ten Formula 1 flags

In 2026 Formula 1 is easily one of the most sophisticated sports on the planet. Some of the best drivers in the world pilot machines that use cutting-edge technology from many different disciplines including aerodynamics, powertrain tech – and increasingly computing. And yet, simple flags remain the main point of communications between race directors and the drivers on track.

Whether they’re shown on modern, high-tech light boards – which can be operated by race control or trackside by marshals – or waved by marshals, flags are vital when it comes to the running and safety of grand prix races.

Some flags appear much more frequently than others, and that means even the most avid of Formula 1 fans may not know what some of the less-used flags actually indicate. As cars improve and the nature of racing changes, some flags haven’t been shown for some time.

On this page we’ll break down every flag available to Formula 1 marshals, from the common ones, to the more obscure ones that are rarely seen.

What does each flag mean in F1?

What does a green flag mean?

Green is the flag we all want to see: it means normal racing conditions apply and drivers are permitted to drive as fast as they dare.

Aside from being waved by at the start of every race — by a marshal at the rear of the grid to indicate that all cars are in place — the green flag is also used to resume racing after a safety car restart or to signal that the circuit is safe following an incident.

In addition, it’s also used to mark the end of a yellow flagged sector – allowing cars to return to racing speed on parts of the circuit where there is no longer a danger or threat.

The green flag is perhaps the most simple and commonly used of all track-side markers, but it can still catch some drivers out, as Sergio Perez found out at the 2022 French Grand Prix. Following a Virtual Safety Car (VSC) period, where drivers are required to reduce their speed so an incident can be cleared, George Russell caught Perez napping as the VSC ended, leading to Russell snatching second place when the race went green.

What does a blue flag mean?

Blue flags are the most commonly-used flags in a race, but are a relatively recent development in Formula 1’s 76 year history.  Introduced in 1995, they’re used by marshals to alert drivers when a faster car, which isn’t fighting them for position, is approaching behind.

This is seen more often in seasons such as the current one, where there is a vast difference in pace between teams at the back such as Cadillac and the frontrunning Mercedes.

In practice or qualifying, blue flags are used to warn drivers of another driver on a fast lap. In the race, it signals to a driver that they are about to be lapped and must let the faster car through at the next available opportunity. Passing three blue flags without giving way can result in a penalty.

While they must be adhered to, blue flags can be difficult for drivers who are entrenched in their own battles at the back of the grid, who don’t want to lose too much time letting the lead cars through at an inopportune moment. But luck plays a part too, as certain parts of a track will be easier to let someone through than others, meaning both the lead cars and lapped cars can suffer under blue flags.

What does a yellow flag mean?

Yellow flags mean caution, either on the track or right next to it, and drivers are expected to slow down immediately. Overtaking is banned under yellows, and anyone who doesn’t ease off quickly enough — as monitored by F1’s telemetry — can expect a penalty. How the flag is waved tells you the severity of the situation is.

A single waved yellow is the mild version, warning of a hazard ahead. Drivers have to lift off and be ready to change direction, but don’t have to slow their pace substantially. At the 2026 Austrian Grand Prix, George Russell qualified on pole despite his lap being affected by single yellow flags. His “massive lift” through the yellow flag section cost him 0.15sec, according to his Mercedes team. Race officials accepted that he had reacted sufficiently to the flags.

Double-waved yellows require a stronger response, and are deployed if there is a hazard wholly or partly blocking the track, marshals out working on or beside it, or a crashed or stranded car at the trackside. Drivers must slow significantly, so that they are prepared to stop or drive around any obstacle.

Yellow flags are waved at all marshal posts around a circuit during any virtual safety car period, which requires drivers to slow to a pre-set lap time; maintaining the gaps between the field, while reducing the risk to marshals working trackside.

For more serious incidents, the safety car is deployed. Driver must form a line behind the car, and this bunching up of the field creates a gap where marshals can safely work on the track for brief periods.

Yellow flags have caused their fair share of arguments over the years, particularly in qualifying. Drivers who don’t slow down enough under yellow have had lap times deleted or picked up grid penalties for it: Max Verstappen and Valtteri Bottas both fell foul of this at the 2021 Qatar Grand Prix.

They’ve also been a source of controversy. In the past drivers have been accused of triggering a yellow flag on purpose, either by driving slowly or crashing outright to protect their grid slot; Sergio Perez was accused of this by his own team-mate at Monaco in 2022. The Red Bull driver spun at Portier at the end of the final Q3 session, having set the third-fastest time. This prevented anybody else from going faster and Max Verstappen, who was stuck in fourth, was convinced it wasn’t an accident. Perez went on to win the race the next day.

What does a red flag mean?

The red flag is shown to halt the race, typically due to poor conditions — such as heavy rain or fog — or a serious accident that needs immediate intervention. When used, it is waved at every marshal post around the track as well as the start/finish line. Drivers must make their way back to the pitlane and will significantly reduce their speed in doing so, or remain stationary if they cannot continue driving safety.

While no grands prix (not including sprint races) were red-flagged in 2025, between 2021 and 2024, 19 red flags were used to stop Formula 1 grands prix, which is six more than the entire previous decade put together.

The use of the flag has increased as race officials give greater priority to the safety of track workers and drivers, particularly after the death of Jules Bianchi, whose Marussia slid into a recovery vehicle, causing ultimately fatal injuries at the 2014 Japanese Grand Prix. The weather conditions seen in that race would have likely seen a red flag today as we saw in Spa 2021 and Suzuka 2022, while red flags are regularly used when recovery vehicles are needed on track.

Red flags are also often used when extensive barrier repairs are needed, following crashes.

What does a black flag mean?

The black flag is the Formula 1 equivalent football’s red card – disqualifying drivers and forcing them to return to the garage immediately. It’s also usually accompanied by the driver in question’s number on a digital board, to clarify who is receiving the notice.

It’s an unusual sight: the last black flag was waved in 2024 at the Sao Paulo Grand Prix, in response to Nico Hülkenberg being illegally pushed back onto the circuit by marshals. It was the first time that the flag had been seen in F1 since 2007, when Felipe Massa and Giancarlo Fisichella left the pitlane while the exit lights were red.

The black flag does not discriminate, though. F1 legends such as Ayrton Senna, Nigel Mansell and Michael Schumacher all saw the black flag waved in their direction during their careers — either for driving dangerously or for breaching the rules.

Only one driver has been black-flagged from a race for driving too slowly: British-Canadian driver Al Pease who held up eventual race winner Jacky Ickx on several occasions at the 1969 Canadian Grand Prix.

What does a black and white flag mean?

Keeping with the football analogy, the black and white flag serves as F1’s yellow card: warning drivers directly via digital boards of a breach in the rules or after an act of unsportsmanlike behaviour.

This is usually accompanied by a radio message from the team, letting their driver know that their misdemeanour has been noted. If drivers don’t heed the warning then they can expect a more severe penalty. For example, drivers can breach track limits three times over the course of the race before being issued a warning through a black and white flag. Should they cross the limit one more time after that, they will receive a penalty.

Should they continue to accumulate more black and white flag warnings, they could ultimately end up being disqualified.

What does a black and orange flag mean?

The black and orange flag is waved toward a driver who has a mechanical issue likely to endanger themselves or others and must pit to resolve it. Once fixed to the stewards’ satisfaction, the driver may re-join the race.

While fairly uncommon, the use of the black and orange flag can be quite inconsistent, as it relies upon the stewards to determine the severity of the damage.

After qualifying a brilliant fifth, Haas driver Kevin Magnussen damaged a front wing end plate during the start of the 2022 Canadian Grand Prix and was forced to pit for repairs despite him insisting that the car was still drivable. He re-emerged back on track in last place and ultimately finished 17th.

The black and orange flag is usually accompanied by the driver in question’s number on a digital board, to clarify who is receiving the notice.

What does a white flag mean?

The white flag is used to warn drivers of a much slower-moving or stationary vehicle on track.

This will most often be seen on the last corner and/or pit straight of a track at the end of a practice session, when drivers will perform practice starts on the grid.

It can also be used to signal a miscellaneous vehicle such as a medical car on track.

What does a red and yellow striped flag mean?

The red and yellow flag signals a loss of grip in the area after the flag, which is held motionless and never waved, to avoid confusion with yellow flags.

This could be due to water, oil, or gravel on track.

What does a chequered flag mean?

What better way to end than with the chequered flag?

Waved at the end of every grand prix and the end of every practice and qualifying session, the chequer can spell joy or dismay for any Formula 1 driver. Although it has become an activity for celebrities over the years (who from time to time get it wrong) and even having ended races early due to some technological blunders, it remains the definitive indicator that a race has ended.

What are light panels? 

High-tech light panels have been made mandatory at all F1 circuits since 2022, as part of a new safety partnership with the FIA.

Acting as an alternative to the traditional flag system, light panels can be operated by both trackside marshals as well as race control and can display crucial information to drivers on track including weather status, flag information or whether safety car or virtual safety cars have been deployed.

Not only can they be seen more clearly by competitors in almost any condition, but they can also be deployed on parts of the circuit where there are no marshal posts nearby — ensuring that drivers can remain safe no matter where they are on the circuit.
