Three reasons to get a smog check

Registration renewal

Every two years on most vehicles you must get a smog check to renew your registration with the DMV. Gasoline vehicles newer than 6 years, hybrids, motorcycles, gasoline vehicles 1975 or older, and diesel vehicles 1997 and older are generally exempt.

Change of ownership

Most vehicles need a smog check when bought or sold. It is the seller's responsibility to have the vehicle inspected within 90 days of the transaction. Gasoline vehicles newer than 4 years, hybrids, motorcycles, gas vehicles 1975 or older, and diesel vehicles 1997 and older are generally exempt, and transfers between certain family members may not require one.

Bringing in a car from out of state

Most cars coming from out of state seeking California registration need to be smogged. Hybrids, motorcycles, gasoline vehicles 1975 or older, and diesel vehicles 1997 and older are generally exempt.

Common questions

Smog repair & assistance

Can you retest the vehicle after the smog repair?

Yes — we are an authorized smog check test and repair shop. If your 2000-or-newer vehicle was smog checked by us, you are entitled to a free retest within 60 days of the original test, except on select promotions that exclude it. If you used a different smog check station, you will need to pay for the smog check we perform.

What do I do if it's going to cost a lot for the smog repair?

You may be eligible for financial assistance from the California Consumer Assistance Program, which offers up to $500 to qualifying owners for emission-related repairs. If you don’t qualify, ask us about our financing program.
