Yellow Flag: A yellow flag will signal a potential hazard on or near the track, including items covered by white flag in a racing situation like debris or fluid. The flag may displayed motionless or standing if an object is far off the surface, but waved vigorously for things causing greater danger. Essentially, the greater the danger, the harder the flag should be waved.
Waving Yellow: This should be used for any on track hazard that would normally have a waving yellow, debris or white flag.
Standing Black Flag: This should be used with another furled flag to “point” at the car being black-flagged.
Reasons to Black Flag a Participant:
Spin (anything more than 90 degrees sideways, on or off track)
2-wheels off (more than raising dust at corner entry/exit or apex)
4-wheels off
Not giving a point-by to faster drivers
Crossing over the blend line instead of merging into traffic
Continuous over-the-edge driving
Waving Black Flag: This will be used at all stations as a black-flag all.
Blue Flag: This will be used to let drivers know they should give a point-by to the car or cars behind them as soon as allowed or comfortable.
Red Flag: This one will be used to let drivers know they need to pull to a stop smoothly and safely to the side of the track. (but still on the surface so as not to cause grass fires) Which side doesn't matter, as long as there is a lane in the middle for rescue vehicles. Wait to move until further signals are given by corner workers or other officials. Drivers are to stay stopped until there is some signal from an official it is safe to proceed.
Checkered Flag: This flag shall be used to end the session. It may be used at multiple places around the track.
