Green means everything is normal, and you can go. You will usually see this flag near the track start/finish line.

There is a faster driver approaching you, please let them overtake at the next safe passing zone.

Slow down to about 60% speed. There is a hazard on the track ahead, like dirt, gravel, oil, or a car that spun out. Stay alert and do not overtake. Sometimes, there will be a yellow flag with red stripes to indicate dirt, gravel, or oil on track.

For the first lap of the day, there may be yellow flags for the entire length of the track to help drivers identify the flag stations.

Same as standing yellow, except there is an immediate incident up ahead so be ready to take evasive action.

If you get black flagged, it means something you did is cause for concern (e.g. spinning, going off track, or reckless driving). Pull into the pit lane and talk to the track official. Generally, if you are black flagged 3 times, you’re done for the day.

Something happened and all drivers must exit the track. Return to pit lane until further instruction.

Something is wrong with your vehicle and has been noticed by track staff (e.g. windows not down, trunk unlatched, car smoking). Pull into pit lane and meet with the track official.

An emergency occurred on the track that requires the session to stop (e.g. a tow truck or emergency vehicle needs to enter the track to attend to a crashed car). Pull over to the side of the track within view of a flag station and await further instruction.

The session is over. Complete the rest of the lap as cooldown and exit the track at the next opportunity. Do not try to run an extra lap. This will likely earn you a black flag and delay the next group.

You will see this flag at start/finish and sometimes at another flag station on the track.
