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. It’s ironic then, that simple flags are the main point of communications between race directors and the drivers on track.

Whether they’re shown on modern, high-tech light pens – which can be operated by race control or trackside by marshals – or waved by marshals, flags are a 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 now know what each flag actually indicates. As cars improve and the nature of racing changes, some flags haven’t been show in decades.

On this page we’ll break down every flag available to Formula 1 marshals, from the easy common ones, to the more obscure ones you may have never seen before.

What does each flag mean in F1?

What does a green flag mean?

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

Aside from being waved at the start of every race, 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?

Believe it or not, blue flags haven’t always been part of Formula 1. Introduced in 1995, they’re used by marshals to alert drivers of a faster car behind them, and they’re common place in most races nowadays – especially this season, when you have a huge in difference in pace between teams such as Cadillac and Mercedes for example.

In practice or qualifying, this may be used to warn drivers of another driver on a fast lap and not to slow them down. 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, 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 with that in mind drivers are expected to slow down immediately. Overtaking is banned under yellows, and anyone who doesn’t ease off quickly enough 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 – it means there’s a hazard beside or partly on the track, so drivers need to back off and be ready to change direction. Double waved yellows are the stronger warning: a hazard wholly or partly blocking the track, or marshals out working on or beside it. Same instruction, more urgency – slow down enough that you can genuinely stop or swerve, not just lift off for a second.

Sometimes a yellow comes with a board reading “SC” or “VSC”, which means a safety car (real or virtual) is about to bunch the whole field up while the incident gets sorted.

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 on purpose, either by driving slowly or crashing outright – just to protect their grid slot. Sergio Perez got exactly this accusation thrown at him by his own team-mate. At Monaco in 2022, he spun at Portier – Verstappen was convinced it wasn’t an accident. Perez qualified third off the back of it, with Verstappen stuck behind him in fourth, and went on to win the race the next day. Rosberg faced the same accusations in 2014, also at Monaco.

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. When used, it iswaved 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.

20 red flags have been used during the last four F1 seasons alone — which is seven more than the entire previous decade put together.

This is likely due to the increase in concern for safety in Formula 1, particularly after the death of Jules Bianchi in 2014. The weather conditions seen in that race would’ve likely seen a red flag today as we saw in Spa 2021 and Suzuka 2022.

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.

Newer F1 fans may be forgiven for raising their eyebrow at this one, as the black flag has not been waved 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.

But to this day, 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.

But 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 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 change of surface and/or loss of grip in the area after the flag.

This could be due to water, oil, or anything deemed necessary for the flag to be waved.

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 prevails as one of the most iconic symbols in all of motor sport.

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 SC or VSC’s 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.
