NASCAR officials will begin enforcing the speed limit on pit road during Monster Energy NASCAR Cup Series qualifying starting this weekend at Auto Club Speedway.
The same pit-road speed used for the race — which varies from track to track — will be used in qualifying.
A driver exceeding the pit-road speed exiting onto the track will be called back down pit road before becoming eligible to post a qualifying time.
A driver exceeding the pit-road speed returning to pit road will have his/her time posted on the previous set of qualifying laps disallowed.
