Racing flags
Racing flags are signals shown by corner workers to warn drivers of hazards and control the session, from green to checkered.
Also called: flags, flag signals, track flags
Flags are how corner workers talk to you. Common HPDE and club meanings: green means the track is clear and the session is live. A standing yellow means caution, a hazard ahead, no passing. A waving yellow means greater danger, slow down and be prepared to stop. Red means stop safely and quickly as your organization directs, usually at the side of the track where workers can see you.
Black means come into the pits, either for you or for everyone. Black with an orange disc, the meatball, means your car has a mechanical problem. Blue with a yellow stripe means a faster car is behind, so check mirrors and be ready to give a point-by. White usually means a slow vehicle on track, though some groups use it differently. Red and yellow stripes warn of a slippery surface or debris. Checkered means the session is over: take a cool-down lap and come in.
Look for every flag station on every lap, and learn where they are during your first laps. Each organization explains its flags in the drivers' meeting, and that briefing has the final word.
Flags warn you about hazards you cannot see yet; missing one is among the most dangerous mistakes on track.
Hazard ahead. Slow down, no passing, be ready to change line. Waving means slow more.
Common meanings at HPDE and club events. Every organizer confirms its own flags at the drivers' meeting, and that briefing has the final word.
