Smog Check Service

Gross Polluter Smog Check in Sacramento

If your vehicle has been flagged as a gross polluter, only a STAR-certified station can certify it. We are one.

What is a gross polluter?

The state's Smog Check Reference Guide defines a gross polluter as a vehicle whose tailpipe emissions exceed the gross polluter exhaust emissions standards. A vehicle identified this way can only be certified by a STAR test-only station, a STAR test-and-repair station or, when applicable, a Referee facility. An ordinary smog station can't issue the certificate.

Repair help may be available

According to the same guide, gross-polluting vehicles may be eligible for the state's Consumer Assistance Program (CAP) or a repair cost waiver. Government agency vehicles and permanently registered fleet vehicles are the exceptions. Check the state's Bureau of Automotive Repair website for the current program rules.

What to expect at our station

• We test the vehicle and explain the result plainly.
• If it doesn't pass, we point you toward next steps so you know what to fix before you come back for a retest.
• Testing a gross polluter can take a bit longer than a standard check, so plan for extra time.

Our gross polluter retest guide walks through what happens after a fail.
