NASCAR Implements New Stage-Break Procedure to Cut Late-Stage Caution Laps

Beginning with the weekend at Iowa Speedway, NASCAR will treat any natural caution that occurs with ten or fewer laps remaining in Stage 1 or Stage 2 as the official end of that stage. The leader will cross the start-finish line under yellow and receive the green-and-white checkered flag together with the caution flag. Stage points and the top-10 finishing order will be set from the running order at the moment the caution is displayed, using scoring loops and video review. The same caution period will serve as the scheduled stage break, allowing teams to pit before racing resumes under green. The rule applies to the Cup Series, the Xfinity (O’Reilly Auto Parts) Series, and the Truck Series for the remainder of the 2026 season.

The change follows fan and competitor frustration after the July 26, 2026 Brickyard 400 at Indianapolis Motor Speedway, where a late-stage caution triggered an extended sequence of yellow-flag laps before the scheduled stage break. Observers noted that up to 30 of the final 35 minutes of the stage were run under caution, prompting complaints of “back-to-back cautions” and “elongated caution laps.”

NASCAR CEO Steve O’Donnell announced the adjustment on social media, saying the sanctioning body had “listened to fans” and acted to reduce “long periods of caution laps and not enough green-flag racing.” He described the new procedure as a way to preserve the existing stage format while eliminating unnecessary yellow-flag interruptions.

Current and former drivers expressed approval. Denny Hamlin highlighted the reduction of prolonged cautions, while former champion Mark Martin posted a thank-you message to O’Donnell. JR Motorsports owner Dale Earnhardt Jr. called the update “necessary” and said it should help “move things along.” Brad Keselowski offered a brief endorsement, urging NASCAR to continue gathering fan feedback.
