Signal Flags

Flag signals are used to designate specific time or to give instructions to contestants. Briefly, the flags and their purposes are as follows:
	Black	Course is closed, return to pits; do not leave pits.
	Red	STOP! STOP! Be alert and watch for other signals. The discharge of red or orange smoke/aerial flares in conjunction with RED FLAGS is advised.
	White	Time between one-minute signal and start; leader has started last lap.
	Green	Time between five-minute and one-minute signal; while race is underway except last lap.
	Blue/White	CAUTION: Problems on race course, continue with caution.
	Checkered	FINISH.
