What are the different NASCAR flags?

Green - Race is starting/retstarting

Yellow - Race is under caution

Red - Race must stop

White - 1 lap left to go

Black - Driver must come to pits

Black w/ a white X - Driver has not come to pits within 5 laps and they are no longer being scored

Blue - "courtesy" flag or the "move over" flag. It is the only flag that is optional. A driver may, at his discretion, ignore this flag.

Checkered - Race it over
