yellow flag (Caution)
A yellow flag, often referred to as a caution flag, is a signal used in various sports, particularly in auto racing. It indicates that there is a hazard on the track, such as an accident or debris, and drivers must slow down and be prepared to change their position. The yellow flag warns participants to exercise caution and maintain a safe distance from one another.
In addition to auto racing, yellow flags are also used in other sports like football and sailing to signify caution or a temporary halt in play. The purpose of the yellow flag is to ensure the safety of players and officials while addressing the situation at hand.
