NASCAR’s primary rule change in the off-season was a reduction in the number of over-the-wall crew members for pit stops from six to five. Carrying tires, changing them and jacking the car will now be performed by a group of four, one member of which will do double duty. A fifth person will fuel the car but is prohibited from doing anything else. A light-duty sixth crew member will be allowed but only to assist the driver by providing food or drink and changing windshield tear-offs. The primary reasons for the reduction are to (1) reduce the number of team members on pit road for safety reasons and (2) highlight the athleticism of over-the-wall crew members, some of whom will now adapt to multiple jobs during stops.
