Smog Facts

Who needs a smog check?

There are three reasons to get a smog check.

Registration Renewal: Every two years on most vehicles you are required to get a smog check to renew your registration with DMV. Gasoline vehicles newer than 6 years old, hybrids, motorcycles, gasoline vehicles 1975 or older, and diesel vehicles 1997 and older are exempt from this requirement

Change of Ownership: Most vehicles need a smog check when they are bought or sold. It is the seller’s responsibility to have the vehicle inspected within 90 days of the transaction. If the vehicle is not registered within 90 days of being smogged it will need to be inspected again. Gasoline vehicles newer than 4 years old, hybrids, motorcycles, gasoline vehicles 1975 or older, and diesel vehicles 1997 and older are exempt from this requirement. Also, transfer of title between certain family members does not require a smog check. Get State Information

Bringing in a car from out of state: Most cars coming from out of state seeking registration in California need to be smogged.Hybrids, motorcycles, gasoline vehicles 1975 or older, and diesel vehicles 1997 and older are exempt from this requirement.

Can you smog my all-wheel drive vehicle?

Yes. All-wheel drive vehicles are smogged doing a two-speed idle test rather than being tested on a dynamometer.

My renewal notice doesn’t specify that I need to go to a test-only center. Can you still smog it?

Yes. We can perform a smog test on your car whether or not it has been directed to a test-only center.

Can you send my smog results to the DMV if I don’t have my renewal form?

Yes. We use the Vehicle Identification Number that is imprinted on the vehicle itself to identify the vehicle with the DMV.

Will my car pass with the check engine light on?

No. However, you may still want to have your car smogged anyway so you can take advantage of the Consumer Assistance Program to help pay for repairs. California has the Consumer Assistance Program (CAP) to help cover the expenses of emissions related repairs.

Will my car pass with an aftermarket air intake or other modification?

Aftermarket parts such as air intakes need a sticker with an eo# affixed to the vehicle to prove that those parts are legal for street use in California. If you have specific questions about specific parts on your car, ask us before we start the smog check, not after we start. View CA’s Aftermarket Part Lookup Resource

What paperwork will I need to complete my Registration Renewal?

The Registration Renewal form that was mailed to you by the DMV helps things go smoother. If you do not have access to that form you can just bring the current registration. If you do not have either of those articles, please inform the service representative and the necessary paperwork will be provided for you in the office. The process generally takes less than two minutes. Should there be any complications we will be able to inform you within five minutes
