STAR Smog Check

California requires most registered vehicles to pass a smog check before registration renews. We are a licensed STAR station that both tests and repairs, so a vehicle that fails gets diagnosed, fixed, and retested without going anywhere else.

Test-only versus test and repair

A test-only station is licensed to inspect and nothing more. When your vehicle fails there, you take it somewhere else for repair, then bring it back for a retest, which is three trips for one problem. A test and repair station like ours handles all three steps, and the technician who found the failure is the one who fixes it.

What a STAR license means

STAR is a designation from the California Bureau of Automotive Repair for stations meeting a higher performance standard. The state directs certain vehicles to STAR stations specifically, and your DMV renewal notice tells you whether yours is one of them. Being STAR licensed means we can handle a directed vehicle and a routine renewal alike.

The Consumer Assistance Program

The state runs a program that helps income-eligible owners repair a vehicle that failed its smog check, or retire it from the road. We serve Consumer Assistance Program participants. Bring your paperwork and we will work within the program requirements rather than around them.

How results reach the DMV

Certificates transmit to the DMV electronically once the vehicle passes, so there is no form for you to carry or mail. Bring your renewal notice and the vehicle, and call ahead so a smog technician is free when you arrive.

STAR Smog Testing: questions we get asked

How often does California require a smog check?

Most vehicles registered in California need one every two years to renew registration. Your DMV renewal notice states whether yours is due this cycle and whether it must go to a STAR station. Certificates are also required on many used-vehicle transfers and when registering a vehicle brought in from another state. Call with the year and type of vehicle and we will tell you what the state requires.

Which vehicles are exempt from smog check in California?

Gasoline vehicles from model year 1975 and older are exempt, as are electric vehicles, motorcycles, and most trailers. Gasoline vehicles eight model years old or newer skip the biennial test and pay a smog abatement fee with registration instead. Diesel vehicles from 1998 and newer under 14,001 pounds do require testing. Your renewal notice is the authority for your specific vehicle.

Will my car fail if the check engine light is on?

Yes. An illuminated check engine light is an automatic failure no matter how well the car drives, because the light means the onboard computer has stored a fault it wants addressed. Clearing the code right before a test does not help either: the readiness monitors reset and the vehicle fails for incomplete readiness. Fix the cause, then test.

What happens if my vehicle fails the smog check?

You get told what failed and why, in plain language, before any repair starts. Because we test and repair, the diagnosis and the fix happen here and we retest when the work is done. A failure at a test-only station turns into two more trips somewhere else.

How long is a smog certificate valid?

A California smog certificate is good for 90 days from the date of the test. If your registration renewal is further out than that, time the test so the certificate is still valid when you renew.

Do I need a smog check when I buy or sell a used car?

California requires a valid smog certificate on most used-vehicle transfers, with exceptions for newer vehicles and transfers between certain family members. The specifics depend on the vehicle year and the type of transfer, so call with the details rather than guessing.

Do I need an appointment?

Call (760) 343-3535 first. We schedule so a smog technician and the equipment are free when you arrive. Walking in without calling can mean a wait.

Can you smog a motorhome?

Usually yes, and the size of the rig is the part that stops most stations rather than the rules. Gasoline motorhomes fall under the same California requirements as other vehicles, and our bay takes vehicles that will not physically fit elsewhere. Call (760) 343-3535 with the year, chassis, and fuel type so we can confirm before you drive it over.
