F1 flags explained: what every flag means
Formula 1 uses 10 racing flags to signal track conditions and driver conduct. In short: green means the track is clear, yellow means danger and no overtaking, red stops the session, blue tells a slower car to let a faster one past, and the chequered flag ends the race. Here is the complete set, with what each one looks like and what the driver must do.
Every F1 flag at a glance
This is the reference most people are looking for — every flag in one place, what it looks like, what it means, and what a driver has to do when they see it:
| Flag | Looks like | Means | Driver must |
|---|---|---|---|
| Green flag | Solid green | The track is clear and racing (or practice) is under way or resuming. | Race normally — overtaking is allowed again. |
| Yellow flag | Solid yellow (single or double waved) | Danger ahead — slow down and do not overtake. Double yellows mean a serious hazard. | Slow down, be ready to change direction, no overtaking. |
| Red flag | Solid red | The session is stopped immediately. | Slow to a controlled pace and return to the pit lane. |
| Blue flag | Solid blue | A faster car is behind you and about to lap you — let it past. | Move aside and let the faster car through at the next opportunity. |
| White flag | Solid white | A slow-moving vehicle is on the track ahead. | Be alert for a much slower car or recovery vehicle in the sector. |
| Black flag | Solid black, shown with a car number | You are disqualified — return to the pits immediately. | Return to the pit lane and report to the stewards; your race is over. |
| Black-and-white flag | Diagonally split black and white, shown with a car number | A warning for unsporting behaviour — a yellow card, in effect. | Rein it in; a repeat can bring a penalty. |
| Black-and-orange flag | Black flag with an orange disc, shown with a car number | Your car has a mechanical problem — come to the pits to fix it. | Return to the pits to have the fault repaired before continuing. |
| Yellow-and-red striped flag | Vertical yellow and red stripes | The track surface is slippery ahead — oil, water, or loose debris. | Expect reduced grip in the sector; adjust accordingly. |
| Chequered flag | Black-and-white checkerboard | The session or race is over — you have crossed the finish line for the last time. | Complete the lap and slow down; racing has ended. |
Each F1 flag, in detail
Green flag
The green flag signals that a hazard has cleared and normal racing resumes. It is waved at the marshal post immediately after a yellow-flag zone to tell drivers the danger is behind them and overtaking is permitted again, and it is shown at the start of a formation lap and at the end of the pit lane during practice. In short: green means go.
Yellow flag
A single waved yellow warns of a hazard beside or on the track in that sector: drivers must slow down, be ready to change direction, and must not overtake. Double waved yellows signal a greater danger — marshals working, or a car stopped on the racing line — and require drivers to slow significantly and be prepared to stop. Ignoring yellows is heavily penalised, and any lap time set through a yellow sector in qualifying is deleted.
Red flag
The red flag stops the session. It is shown when conditions are too dangerous to continue — a heavy crash, debris across the track, or rain beyond the point where cars can race safely. Drivers must slow to a controlled speed, stop overtaking, and make their way back to the pit lane, where the field waits until the session can restart or is abandoned. In a race, a red flag can bunch the field back up and reshape the strategy of everyone still running.
Blue flag
The blue flag is shown to a slower car about to be lapped by a faster one, telling the slower driver to let the quicker car past at the first safe opportunity. It keeps leaders from losing time in traffic. A driver who ignores three blue flags in a row can be penalised, so backmarkers are expected to yield promptly rather than defend against a car on a different lap.
White flag
The white flag warns of a slow-moving vehicle in that sector — a car limping back to the pits, or a recovery vehicle. Note the common point of confusion: in Formula 1 the white flag does not mean “hazard, slow down” in the way a yellow does, and it does not signal the final lap as it does in some other motorsport series. It simply tells you something much slower than racing pace is on the track ahead.
Black flag
The black flag, shown together with a driver's car number, is a disqualification: that driver must return to the pit lane immediately and take no further part in the session. It is a rare, serious sanction, used for a severe breach of the rules or for ignoring earlier warnings. Unlike a penalty served during the race, the black flag ends the driver's participation entirely.
Black-and-white flag
The black-and-white flag, divided diagonally and shown with a car number, is a formal warning for unsporting conduct — repeatedly exceeding track limits, or driving that pushes the boundaries of the rules. It functions like a football yellow card: a single, unambiguous notice that the next offence is likely to bring a time penalty. It is a caution, not a punishment in itself.
Black-and-orange flag
Known as the “meatball” flag for the orange disc at its centre, the black-and-orange flag is shown with a car number to tell that driver their car has a mechanical problem — a loose bodywork part, a fluid leak, or damage that could endanger others. The driver must pit to have it repaired before rejoining. It is not a penalty: it is a safety instruction to fix a car that is unsafe to continue as it is.
Yellow-and-red striped flag
The yellow-and-red striped flag warns of a slippery surface in that sector — oil or another fluid on the track, water, or gravel and debris dragged onto the racing line. It is held still rather than waved. Unlike a yellow it does not forbid overtaking, but it tells drivers to expect a sudden loss of grip where they might not otherwise anticipate one.
Chequered flag
The chequered flag is the one everyone knows: waved at the finish line, it marks the end of a practice session, qualifying, or the race. The leader takes it first, and every other car is classified in the order it crosses the line afterwards. Once a driver has taken the chequered flag they complete a slow-down lap and return to the pits or parc fermé.
Flags and the trackside light panels
Waved flags are the oldest signalling system in motorsport, but they are no longer the only one. Since 2022 every Formula 1 circuit has been fitted with trackside light panels that display the same signals electronically, so a driver travelling at more than 300 km/h sees a bright, unambiguous light rather than relying on spotting a marshal’s flag. The panels show the same colours — green, yellow, blue and the rest — and are controlled by race control alongside the marshals still waving the physical flags. The meanings on this page apply to both.

F1 flags — FAQ
How many flags are there in F1?
There are 10 racing flags used in Formula 1: green, yellow (single and double), red, blue, white, black, black-and-white, the black-and-orange “meatball”, the yellow-and-red striped flag, and the chequered flag. Each is a signal from race control to the drivers about track conditions or their own conduct.
What does the yellow flag mean in F1?
A single waved yellow warns of a hazard beside or on the track in that sector: drivers must slow down, be ready to change direction, and must not overtake. Double waved yellows signal a greater danger — marshals working, or a car stopped on the racing line — and require drivers to slow significantly and be prepared to stop. Ignoring yellows is heavily penalised, and any lap time set through a yellow sector in qualifying is deleted.
What does the blue flag mean in F1?
The blue flag is shown to a slower car about to be lapped by a faster one, telling the slower driver to let the quicker car past at the first safe opportunity. It keeps leaders from losing time in traffic. A driver who ignores three blue flags in a row can be penalised, so backmarkers are expected to yield promptly rather than defend against a car on a different lap.
