The official who uses different colored flags to communicate with the drivers. He stands in a tower over the racetrack, just above the start/finish line. The flag colors signify different things to the drivers.

Green: Besides being the signal to start, this flag will remain up while the racetrack is clear and full racing speeds are allowed.

Yellow: Alerts drivers of an accident or a roadway hazard, and the cars must slow to a line behind the pace car. When this flag is displayed, the pace car is in control of the track and a driver cannot advance his place by passing the pace car or other competitors.

White: The lead car is on the final lap of the race.

Black: Waved to a specific driver if officials think there are problems with the race car or are penalizing the driver. They must pull off the track to the pit, and if he ignores the flag he is subject to disqualification.

Blue with Yellow Stripe: Specific cars will receive this flag when faster traffic is approaching and they should allow the car that is lapping them to pass without hindrance.

Red: Cars must stop immediately when this flag is signaled because there is an emergency situation where the track is blocked or needs extensive clean-up from an accident. Also may be shown if the race is stopped by rain.

Checkered: The lead car has finished the race and the race is officially over.Frontstretch: The section of race track between the fourth and first turns. The flagstand and start/finish line is typically located in the center.
