F

Flag A colored signal shown by marshals (or as lights) around the circuit to communicate important information to drivers about track conditions, dangers, and race status.

Green flag:The track is clear. Normal racing can continue and drivers are free to overtake.

Yellow flag – Danger ahead. Drivers must slow down, be ready to change direction, and are not allowed to overtake.

Red flag– Session or race stopped. Conditions are too dangerous to continue and all cars must return to the pit lane or line up as directed.

Blue flag – A faster car is about to lap a driver. The slower car must let it pass safely at the next opportunity.

White flag – There is a much slower vehicle ahead, like a recovery or medical car, so drivers should approach with extra care.

Yellow and Red striped flag – Slippery surface ahead, often from oil, water or debris on the track, so grip may suddenly change.

Black flag – A driver is disqualified and must return to the pits immediately.

Black and orange flag – The car has a mechanical or damage problem that could be dangerous; the driver must pit for repairs.

Black and White flag – Final warning for unsportsmanlike driving; if the behaviour continues, a penalty will follow.
