White flag

The white flag is a race signal whose meaning depends on the discipline and the rules of the series, so always check the riders' briefing.

• In motocross, supercross and many national and US series, it shows that the leader has started the last lap.
• In FIM road racing, a waved white flag can warn of a slow-moving vehicle, such as an ambulance or safety car, on that part of the track.
• In MotoGP flag-to-flag races, a white flag signals that riders may enter the pits to change bikes, for example when rain begins.

A white flag with a red diagonal cross is used in road racing to warn of light rain on that section. Learn the flags of your series before the first practice session.
