Racing flags explained
Flags are how corner workers talk to drivers. Green means go, yellow means hazard (slow, no passing), red means stop the session, black means come into the pits, a black flag with an orange disc means your car has a mechanical problem, red-and-yellow stripes mean a slippery surface, and checkered means the session is over.
- Find every flag station on your sighting laps. Check each one, every lap.
- Yellow means no passing until you’ve passed the hazard and the next green.
- Red means slow down safely and stop where directed, not slam on the brakes.
- Your organizer’s drivers’ meeting has the final word on what each flag means at that event.
The flags
Most HPDE and club organizations use the same core set, with small local differences. Tap each flag to see what it means and what you should do.
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.
What to do under yellow
A standing yellow means a hazard is ahead: slow down, be ready to change your line, and don’t pass. A waving yellow means the hazard is closer or more serious: slow more and be ready to stop. Passing resumes after you’ve cleared the incident. Many clubs show a green at the next station.
Black flags are not a punishment
At a track day, a black flag usually means a quick chat: two wheels off, a missed point-by, smoke from your car, or a loose item. Come in calmly at the pit entry, stop where the pit marshal shows you, and listen. A black flag shown to everyone means all cars come in, often to clear an incident.
FAQ
What does a blue flag mean at a track day?
At many HPDEs, a blue flag with a yellow stripe means a faster car is behind you: check your mirrors and give a point-by in the next passing zone.
What does the white flag mean?
It depends on the organization. It often warns of a slow vehicle on track, such as a tow truck, and in racing it can mean the last lap. Confirm at the drivers’ meeting.
Do I stop immediately for a red flag?
No. Slow down safely, check your mirrors, and stop where marshals or your organizer’s procedure tell you, usually off line and in sight of a flag station.
