The diesel rules in brief
California's smog program covers diesels from 1998 and newer with a GVWR of 14,000 lb or less. Diesels from 1997 and older are exempt, and so are diesels over 14,000 lb GVWR. Unlike gas cars, diesels get no newer-model-year exemption, so a recent truck can still need a check. Your DMV renewal notice will also say whether a check is due and whether it must be at a STAR station.
Have this ready when you call
- Year, make and model.
- The GVWR, usually on the door-jamb label.
- Your DMV renewal notice or the documents DMV sent you.
Then call (760) 439-8000 and we'll confirm whether we can test your diesel here.

If the diesel fails
We're test-only, so repairs happen at a test-and-repair or repair-only station of your choice (BAR's Auto Shop Locator lists licensed ones). After the repair, the $30 smog retest applies within 30 days (retest terms). If the check engine light is on, a vehicle will not pass.
