| Yellow Flag |
|
Flag used to slow down the racers in the case of a crash, debris on the course (like car parts), slick fluids on the track or the weather has become a factor with rain. During a yellow flag the pace car, with the top lights flashing, joins up with the race leader and sets a slower speed on the track. This is done to preserve the driving order on the track as cars cannot pass one another under a yellow after crossing the start/finish line. Drivers generally use this time to pit for refueling, new tires and adjustments.
