NASCAR announced Tuesday that it will not permit drivers to run against the wall to gain speed as Ross Chastain did in last year’s Martinsville Cup playoff race.

NASCAR made the announcement in a session with reporters Tuesday at the NASCAR R&D Center.

Chastain drove into the Turn 3 wall and rode it around the track at higher speed than the rest of the field, passing five cars in the final two turns to gain enough spots to make the championship race. NASCAR allowed the move to stand even though some competitors had asked for a rule change leading into the season finale at Phoenix last year.

NASCAR is not adding a rule but stressed that Rule 10.5.2.6.A covers such situations.

That rule states: “Safety is a top priority for NASCAR and NEM. Therefore, any violations deemed to compromise the safety of an Event or otherwise pose a dangerous risk to the safety of Competitors, Officials, spectators, or others are treated with the highest degree of seriousness. Safety violations will be handled on a case-by-case basis.”

NASCAR stated that the penalty for such a maneuver would be a lap or time penalty.
