How the NASCAR Choose Rule Reshaped Oval Restarts and Commitment Marks

Origins at Bristol and Michigan in 2020

Prior to the formal introduction of the choose procedure, only the race leader held the right to select their restart lane. This arrangement frequently created tactical gamesmanship on pit road, where trailing drivers would deliberately brake or decelerate to manipulate their positioning and line up in a preferred groove for double-file restarts. To eliminate these pit-lane maneuvers, NASCAR trialed a lane-selection system during the July 2020 All-Star Race at Bristol Motor Speedway, utilizing an orange V on the racing surface to establish the commitment boundary. Following that exhibition test, officials integrated the procedure into points-paying competition across all three national series starting at Michigan International Speedway in August 2020.

Commitment Violations and Sanctions

The restart process requires each driver to make a definitive choice between the inside and outside lanes before crossing the designated track mark. Under official procedures governing NASCAR choose cone penalties, any competitor who fails to commit to a lane prior to reaching the mark, or who attempts to switch lanes after passing it, is sent directly to the tail end of the longest line. Because race control assesses this sanction before the green flag drops, the field order is adjusted immediately on the racing surface rather than via a timed penalty on pit road.

Track Configurations and Procedural Exclusions

While the choose rule became a fixture on intermediate and short ovals, NASCAR explicitly excluded road courses and superspeedways from the procedure. On the circuits where it does operate, competition officials apply procedural adjustments to coordinate line dynamics alongside standard race-control elements, including wave-arounds and free passes, ensuring the restart order remains structured as cars sort into double-file formation.
