NASCAR explains timing of race-ending caution in Daytona 500

When Ross Chastain's bold move up the middle resulted in he and Austin Cindric spinning into the infield, the final lap of the Daytona 500 was just about to begin.

NASCAR waited a moment and as Cindric's car slid back up the track, NASCAR made the decision to throw the caution. Per NASCAR rules, a caution flag on the final means the field is frozen and the race is over.
