The race-winning No. 48 Chevrolet of Jimmie Johnson passed post-race inspection Sunday at Daytona International Speedway, an event that hearkened in a new era in NASCAR’s deterrence policy.

As part of a policy change, the cars of the first-place and second-place finishers, plus at least one randomly selected car, will undergo post-race inspection at the track. Competition officials said they are targeting a time frame of approximately 90 minutes to two hours to complete the inspection and confirm the race winner.

The No. 1 Chip Ganassi Racing Chevrolet of runner-up Kurt Busch also passed inspection, and the cars of third-place Joey Logano, fourth-place Ryan Blaney and fifth-place Alex Bowman all got looks as well.

NASCAR competition officials announced in January a new model for post-race inspection for all three national series, introducing a system where race-winning teams found in violation of the rule book would be disqualified and post-race inspections would be conducted at the track soon after the checkered flag instead of midweek at the NASCAR Research & Development Center in Concord, North Carolina.

The rules change signals a shift in a long-standing tradition of penalizing an offending race winner with fines, suspensions and/or points deductions, but allowing victories to stand. The new system also accelerates the timetable for thorough post-race technical inspections.

Should one of those cars fail the post-race inspection, the driver and team would receive last-place points and the rest of the finishing order would move up. Disqualified teams also would be stripped of the benefits of playoff points, stage points and automatic postseason berths and playoff advancement.
