Update on NASCAR pit road officiating

Officials in NASCAR's Pit Road Officiating (PRO) trailer called 12 of the 22 penalties issued during Sunday's Auto Club 400, the second fewest through this year's first five races. Six of the 12 were for tire violations — failure to control an outside tire. Only Phoenix saw fewer total violations (19) and those made by officials in the PRO trailer (nine).

There have been 158 penalties thus far this season, including 60 that were called by the PRO group. Officials in the tower continue to call infractions for speeding when entering/exiting pit road, pitting before pit road is open and various safety-related violations. Officials in the PRO trailer use video to respond to potential infractions such as too many crewmen in contact with the pit service area, crewmen over the wall too soon and pit box tire violations.
