Drivers must make their decision before they get to an orange V with a box inside on the track, where drivers will either go left or right. The Choose rule only comes into play on restarts from caution periods.Selecting the right side of the track for restarts is important. When the Choose rule is in action during the races, drivers have the chance to take multiple positions.The rule is used on all tracks, excluding road courses, Daytona International Speedway, and Talladega Superspeedway.Motorsports journalist Bob Pockrass shared the Choose rule on his official Twitter account. The tweet reads:"Once the Choose process begins, if the restart is waived off, then the subsequent line-up will:"“Revert to the order of the vehicles prior to the Choose process, including freeze the field order, use of the pit out camera, penalty vehicles, and vehicle's ability to maintain reasonable speed, as determined by NASCAR”.“At the Series Managing Director's discretion, if the Race is delayed for an extended period, NASCAR may require another Choose prior to the restart.”Bob Pockrass@bobpockrassNASCAR can decide to have the drivers re-choose.
