Following qualifying for the NASCAR Sprint Cup Series event today – where there is no practice between qualifying and the race – the cars will be impounded. This move involves the cars to be escorted to their respective garage stalls by a NASCAR Official (with the exception of the top five cars, which will be placed in a designated area for post-qualifying inspection).
An impound weekend typically featured Friday practice, Saturday qualifying and a Sunday race only at the superspeedways (2+ mile tracks) – Talladega and Daytona. Following qualifying, cars were impounded and could not be altered until the race without penalty. Teams that opted to work on their cars before the race were forced to start at the back of the field. At non-impound races, cars could be worked on after qualifying and before the race. Impounding was implemented as a cost-cutting move.
Once the car is pushed to the garage stall, only two crew members will be allowed to remain in the garage.
The following work list will be allowed:
1. Shut off electrical switches and master power switch;
2. Remove radio;
3. Check air pressure in tires;
4. Cover the car; and,
5. Crew members exit garage and garage doors close.
Pit road selection will be immediately after the last car has qualified.
