Be prepared to encounter a Pace Car and/or emergency vehicles. But remember, It is still wise to assume the car behind you has not seen the yellow flag, so remain predictable.įull course yellow condition exists.

If They are jumping 6 feet into the air and waving the flag like they’re trying to fly, expect IMMEDIATE danger and slow even more than you think you need. Take note of the corner worker’s body language and ferocity of the flag waving. As soon as you see a waving yellow flag, expect the need to take some sort of evasive maneuvers once you go around that corner. Waving yellow flags are the more serious yellow. Note: There may be one (1) yellow flag covering more than one incident. ABSOLUTELY NO PASSING is permitted, until completely past the incident, or until past the next manned flag station that is not displaying any Yellow Flag(s), whichever comes first. It my also be wise to assume the car behind you has not seen the yellow flag, so remain predictable within reason. You do not want to get caught up in an incident with another car. The requirements are still the same, “SLOW DOWN, NO PASSING.”Ī standing yellow flag generally means “don’t be an idiot” so proceed with caution and don’t pass. There may be several yellow flags before reaching the emergency area. There may be one (1) yellow flag covering more than one incident. ABSOLUTELY NO PASSING is permitted, until completely past the incident, or until past next manned flag station that is not displaying any Yellow Flag(s), whichever comes first. If you pass a manned corner station displaying no flag, you can assume green conditions. Note: You will not always get a green flag, often you will simply be entering a green track. In HPDE you will not see this very often, this flag is usually displayed if the morning session begins with a double-yellow lap, the starter will wave the green flag to signify the ending of the yellow opening lap. Flag definitions are generally standard across US Trackday HPDE events, but if you are running with a new club always make sure you check and understand their flag rules. There are some additional combinations for racing that wheel to wheel racers need to know as well. These general definitions ( Italicized) have been taken right from the current NASA rulebook for HPDE. Knowing and understanding these flags must be second nature to you. They are used for general communication as well as commands during an emergency. They are the sole method of communication between you and track officials.

If you ever drive on track, knowing the flags is one of your largest responsibilities.
