Flags

White Flag
Warning that there is a slow car on the track.

Yellow Flag
A yellow flag indicates an accident. Please be extra careful when you see a yellow flag on your screen.

Blue Flag
A blue flag indicates a faster car approaching from behind, and is typically shown on your out lap or when being lapped. Let the driver pass safely to avoid a penalty. Most important is to behave in a predictable manner. In a single class race, or in multiclass races with no topspeed differences between the cars, please move off the racing line in a safe place to let the other driver pass. In a multiclass race with topspeed differences between the cars, you can stay on the racing line. Ignoring blue flags can result in a penalty.

Black and white diagonal flag
A black and white diagonal flag signals when you go off the racing surface. You have to slow down to give back any advantage gained by cutting the track.

Checkered Flag
The leader has finished the race, you must race the remaining lap before you are finished.

Black Flag
A black flag indicates a disqualification.
