How diesel rules work in California

  • Part of the program: 1998 and newer diesels with a GVWR of 14,000 lb or less.
  • Exempt: 1997 and older diesels, and diesels over 14,000 lb GVWR.
  • No newer-model-year exemption. Gas and hybrid cars get their first eight model years off. Diesels don't.

Once we've confirmed on the phone that we can test your diesel here, book or walk in. As always, you approve a written estimate before the inspection.

If a diesel fails

You'll get the vehicle inspection report with the results and any open safety recalls. With the check engine light on, a vehicle will not pass. We're test-only, so we don't do repairs. Emissions repairs are done at a test-and-repair or repair-only station of your choice. Find a licensed repair station with BAR's Auto Shop Locator. Within 30 calendar days of the paid, failed inspection, the $30 smog retest is $21.75, plus the $8.25 certificate on a pass.
