NASCAR changed its stage-break procedure across its national series for the rest of the 2026 season, starting this weekend at Iowa Speedway, in a move aimed at reducing long caution periods and back-to-back yellows. Under the new rule, if a caution comes out with 10 laps or fewer remaining in Stage 1 or Stage 2, that stage will be declared official at the moment of the caution.
After that, the race leader will return to the start-finish line for a green-and-checkered finish under yellow, and the ensuing caution period will count as the stage break. Any remaining laps from that stage will be added to the next stage, and NASCAR said the top-10 finishing order and stage points will still be determined using all available timing and scoring resources.
NASCAR president Steve O’Donnell said the change came after fan complaints about too many caution laps and not enough green-flag racing. NASCAR also said the update lets stage points be awarded right away and allows pit road to open as soon as it is safe.
