How Restart Lane Selection Works and Why Commitment Marks Matter

The Move Away from Pit Road Gamesmanship

In modern stock car racing, starting spot and lane positioning on a restart can significantly impact a driver's momentum heading into the next corner. Before a universal selection system was introduced, only the front-running car held the authority to select an inside or outside lane. This restriction frequently led trailing competitors to deliberately brake or slow down along pit road, attempting to exit pit lane in an order that lined them up on their preferred groove for upcoming double-file restarts. To eliminate these disruptive tactics, NASCAR trialed a dedicated commitment mark during the July 2020 All-Star Race at Bristol Motor Speedway, where a painted orange V indicated the decision point, before bringing the process to points-paying events starting at Michigan International Speedway in August 2020.

Lane Commitments and Grid Reordering

The procedure permits each driver to pick either the inside or outside running line before reaching a designated mark on the racing surface. Maintaining strict adherence to that choice point is mandatory; if a competitor fails to pick a lane prior to the mark or attempts to change directions afterward, officials enforce an immediate setback by placing that car at the rear of the longest restart line. Because these NASCAR choose cone penalties reorder the running grid before the green flag drops, the correction is managed straight on track rather than served as a timed penalty during a routine pit stop.

Where the Procedure Applies Across the Schedule

The lane-choice format extends through all three of NASCAR's national touring series on most conventional ovals. However, officials specifically exclude superspeedways and road courses from using the procedure. In addition to managing these track-specific exclusions, race controllers make operational accommodations during caution periods to handle full-field lineup dynamics, wave-around cars, and free-pass recipients before the field forms up for green-flag competition.
