 If there is another crash/caution before the leader reaches the start/finish line, then the race will continue to be extended until the leader reaches the line.However, when the leader of the race reaches the start/finish line, the next flag (caution or checkered) will end the race (although competitors are required to cross the start/finish line at pace car speed to be scored in their position at the moment of caution).After the race, the winning driver (and, if at the end of the season, championship winning driver) will usually complete a series of burnouts in celebration of their victory, before heading to victory lane for more celebrations and post-race interviews.
