The basics
F1 flags explained: what every flag and safety car means
Flags are how race control talks to the drivers. Today they're also shown on light panels around the track and on the drivers' steering-wheel displays, but the meanings haven't changed in decades.
| Flag | Meaning |
|---|---|
| Green | The track is clear. Racing resumes after a yellow flag zone or at the start of a session. |
| Yellow | Danger ahead, such as a stopped car. Slow down and no overtaking. Two yellows waved together (a double yellow) mean be ready to stop; in qualifying, drivers who don't slow down can have their lap deleted or be given a grid penalty. |
| Red | The session is stopped, usually for a serious crash or bad weather. Cars return slowly to the pit lane. |
| Blue | A faster car is about to lap you: let it through at the first chance. Ignoring blue flags brings a penalty. |
| White | A slow vehicle is on track ahead, such as a recovery truck or a car returning slowly to the pits. |
| Black | Shown with a car number: that driver is disqualified and must return to the pits. |
| Black and white | A warning for unsporting driving or repeatedly exceeding track limits. Often followed by a penalty if it continues. |
| Black with orange disc | Nicknamed the 'meatball'. The car has a mechanical problem, such as loose bodywork, and must pit to fix it. |
| Red and yellow stripes | Slippery surface ahead: oil, water or debris. |
| Chequered | The end of the session or race. |
The safety car
When an incident needs marshals on track but doesn't justify stopping the race, race control sends out the safety car. The field must form a queue behind it at reduced speed with no overtaking. Lapped cars may be told to overtake the queue and rejoin the back, so the restart is a straight fight. Because everyone is slowed down, a pit stop under the safety car costs much less time.
The virtual safety car
For smaller incidents, race control can use a virtual safety car (VSC) instead. There's no physical car: every driver must stay above a minimum time through each part of the lap, shown on their dashboard as a "delta". It slows the whole field considerably while keeping the gaps between cars roughly the same.
Red flags and restarts
After a red flag, cars wait in the pit lane in race order, and teams can change tyres for free. The race then restarts either behind the safety car or with a standing start from the grid. If it can't be restarted, the result is taken from the running order two laps before the red flag was shown (so an incident in progress doesn't decide it), with points scaled by distance: see shortened races.
