California Licensed Smog Test
in Atascadero
California requires most gasoline vehicles 1976 and newer and diesel vehicles 1998 and newer to pass a smog inspection every two years for registration renewal. Vehicles eight model years old or newer are exempt from testing but pay a smog abatement fee instead.
Regular Smog Inspection
We perform the standard biennial smog check required for California registration renewal. Using state-certified OBD-II diagnostic equipment for 1996 and newer vehicles, we test your emissions systems and provide the certificate the DMV needs to process your registration.
Smog Check Failure Diagnosis
If your vehicle does not pass the smog test, we identify the specific reason for the failure and explain your options clearly. Whether it is an emissions system fault, a check engine light code, or a component issue, we diagnose the problem so you know exactly what repairs are needed to pass on the retest.
Change of Ownership Smog Check
Selling or transferring a vehicle in California requires a smog certificate dated within 90 days of the sale. We provide change of ownership smog inspections so you can complete your vehicle sale without delays.
Emissions Repair and Retest
When your vehicle fails a smog check, our technicians perform the necessary emissions repairs to bring your vehicle into compliance. After repairs are complete, we retest your vehicle at no additional charge for the inspection to confirm it passes.
Out-of-State Vehicle Smog Check
Registering a vehicle from another state in California requires a smog inspection. We test out-of-state vehicles and provide the certificate needed to complete your California registration.
Pre-Purchase Vehicle Inspection
Considering buying a used vehicle? We perform a comprehensive inspection covering engine, transmission, brakes, suspension, electrical systems, and body condition to identify hidden problems before you commit to a purchase.
