Bristol Motor Speedway operates under a plan where one-pit road will be used during pit stops under caution. Currently, Bristol remains the only track in the Sprint Cup Series that utilizes two pit roads with 22 pit stalls on the frontstrect and 21 on the backstretch. Teams that pit on the backstretch used to be at a competitive disadvantage. Since the spring 2002 race at Bristol, teams will enter pit road in Turn 2 (the current backstretch pit entrance) drive around down the backstretch and around Turns 3 and 4 and exit in Turn 1. Under green-flag conditions teams will enter and exit pit road under the current two-pit-road scheme.
How are pit stall's chosen? by qualifying draw, the 1st choose their stall and so on.
If a car/driver has to go to the rear of the field before the start of the race due to driver change, backup car,
engine/transmission change, etc they do NOT lose their pit stall selection
