Which flag indicates the conclusion of a racing session?

The chequered flag is the official signal that a racing session has concluded. When displayed at the finish line, it indicates that the race is complete, and all competitors should stop racing. This flag is universally recognized in motorsport and is crucial for signaling to drivers that they must slow down, return to the pits, or prepare for any post-race procedures. Its use is essential for maintaining safety and ensuring that all participants are informed about the end of the session effectively.

The other flags serve different purposes. For instance, the white flag indicates that a slower vehicle is on the track, the black flag signals a driver to return to the pits due to a rule violation, and the yellow flag warns of potential hazards on the track requiring caution. Understanding the meaning of each flag is vital for drivers and teams to adapt their strategies accordingly during the race.
