Multiple sources have told Motorsport.com that NASCAR will implement new procedures for crashed vehicles in the top three national tours this season.

If a car or truck sustains damage during a race and is taken to the garage, that driver will not be able to return to competition.

Damaged cars that cannot be repaired on pit road within five minutes — starting with the time the driver crosses the yellow line at the entrance to pit road to the time he crosses the yellow line at the exit — will be forced to retire from the race.

While on pit road, teams will be allowed to remove or reattach original body parts with fasteners and/or tape. Rods or supports can be used to brace the original panels. However, new panels cannot be used as replacements.

A comprehensive list of mandatory car components required to return to competition will be issued by the series directors.

Drivers guilty of commitment-line violations coming to pit road or are caught speeding will have to serve a 15-second penalty.

Teams will be allowed to repair mechanical failures in the garage if the malfunction did not occur during an accident.
