NASCAR has changed its penalty system for technical infractions, tying specific punishments to specific violations and breaking it into six classes:
P1: Multiple warnings for minor technical infractions. Penalty: could include last choice of pit selection, loss of track time, being selected for post-race inspection, reduction of event passes or community service.
P2: Expiration of certain safety certification or improper installation of a safety feature, or minor bracket or fasteners violations. Penalty: loss of 10 points and/or $10,000-$25,000 fine and/or suspension of crew chief or others for one or more races and up to six months' probation.
P3: Unauthorized parts, measurement failures, parts that fail their intended use, or coil spring violations. Penalty: loss of 15 points and/or $20,000-$50,000 fine and/or suspension of crew chief or others for one or more races; and up to six months' probation.
P4: Devices that circumvent NASCAR templates and measuring equipment, or unapproved added weight. Penalty: loss of 25 points, $40,000-$70,000 fine, three-race crew chief (plus possibly others) suspension and up to six months' probation. If the infraction is found after a race, it is a 35-point penalty and the fine is $65,000-$95,000.
