Definitions for "Black Flag"
Shown in conjunction with a white number to a driver for dangerous or non-sporting on-track conduct. The offending driver must stop at his team's pit within one lap and consult the Clerk of the Course. A black and white diagonal flag is a "once-only" warning to a driver for non-sporting on-track behaviour. A black flag with red spot shown in conjunction with a competitor's number indicates the driver's car has a mechanical problem and he is must stop at his pit.
The signal for a driver to come into the pits, usually to allow officials to inspect it to determine whether it can run safely after an accident. It may also mean that officials have already decided the car is to slow or too dangerous to continue running, as when it has a serious oil leak that makes the track slippery.
A black flag accompanied by a car number, directs a driver to return to his pit and is most often used to signal to the driver that he has been excluded from the race.
