If you are new to HPDE, flags are a good place to start. The following flags are used to communicate various information during the events. Memorize their meanings as they can signify important things and require very specific actions. 

HPDE Flags

Green HPDE flagGreen—This flag is at the start/finish line and generally indicates that the session is in progress, the track is clear and passing is allowed.



yellow hpde flag

Yellow—A yellow flag is used in two different ways. If a corner worker is holding the flag still with both arms outstretched (referred to as ‘standing yellow’), it means passing is not allowed because it’s the warmup lap or there is a problem ahead. If the flagger is waving a yellow flag, slow down and pay attention because there is likely to be a hazard on the track.

Blue with diagonal stripe—This flag tells you there are faster cars behind you and to let them pass.


Red yellow vertical stripes HPDE flagYellow and red vertical stripes—This flag indicates there is something potentially hazardous on the track whether leaked fluids, an animal or other debris. If you see this flag, be cautious.


Black hpde flag

Black—A black flag notifies you that something is wrong with your car or the way you are driving. Ignoring a black flag can ensure your removal from the event. Acknowledge that you see the flag, pit-in and report to the event organizer or track staff to discuss why you received this flag.


Black and orange dot hpde flag

Black with orange circle—The mechanical flag indicates that you have a mechanical problem whether a noticeably loose or missing part or a fluid leak. Slow down and pit in.


Red hpde flag


Red—A red flag signifies an emergency. Check your mirrors and come to a stop toward the inside of the track, in view of a corner worker. This ensures there is a clear track for emergency responders.


White Hpde flag with red crossWhite (with or without a red cross)—A white flag warns drivers that a slow moving vehicle is on the track. These vehicles can include emergency vehicles.


Checkered HPDE flag


Black and white/checkered—The checkered flag marks the end of session. Begin your final cooldown lap and head for the pits. Passing is not allowed on the final lap.


Along with all the HPDE flags, it is also important for you to know that most auto insurance policies do not cover your car on the track. Learn how to check your policy for exclusions.

If your policy has exclusions for your car on the track, don’t worry. We offer HPDE Insurance to protect your car from damage when you’re participating in HPDE, Track Day, or Time Trial events.
