What to bring
Two things: the vehicle and your DMV renewal notice. The notice tells you whether the state wants a smog certification this cycle and whether it must come from a STAR station. If you're buying or selling a car, or registering one that came from another state, bring your DMV renewal notice or the documents DMV sent you. If the notice has gone missing, call us before you drive over and we'll tell you what we need.
How a STAR smog check works here
Check-in
Walk in, or book online to hold a time. We confirm the vehicle details from your notice or registration.
The inspection
Depending on the model year, the inspection includes a computer check of the engine's onboard diagnostics, a visual look at emissions parts, and other checks the state program calls for.
Your results
You get the vehicle inspection report, showing the results and whether the car passed, and we go over it with you before you leave.
For the current price, see our Holiday Special page.

What if your car doesn't pass?
No inspection station can promise a pass — the result depends on the vehicle. If yours doesn't pass, here is what happens:
- We explain the report. You get the Vehicle Inspection Report, and we walk you through which items didn't pass and what they mean in plain language.
- Emissions repairs happen at a station you pick. Emissions repairs are done at a test-and-repair or repair-only station of your choice. Find a licensed repair station with BAR's Auto Shop Locator.
- Retest here. Within 30 calendar days of the paid, failed inspection, the $30 smog retest is $21.75, plus the $8.25 state certificate if the car passes.
One tip: if a battery was just replaced or trouble codes were just cleared, drive normally for a while before coming in. The car's self-tests need time to finish, and an inspection can't be completed until they do.

Frequently asked questions
What is a STAR station?
STAR is a California Bureau of Automotive Repair program. Stations in it have to meet performance standards that the BAR sets and monitors. Some DMV renewal notices say the vehicle must be certified at a STAR station; we can inspect those vehicles, along with any vehicle that doesn't carry that requirement.
What should I bring to my smog check?
The vehicle and your DMV renewal notice. For a sale or an out-of-state registration, bring your DMV renewal notice or the documents DMV sent you.
How often does California require a smog check?
For most vehicles, every two years at registration renewal. Gasoline vehicles in their first eight model years are generally exempt from the every-two-years check (owners pay a smog abatement fee instead). A smog certification is also commonly required when ownership changes and when a vehicle is registered in California for the first time. Your DMV notice is the final word for your vehicle.
What if my car fails?
We explain the inspection report. Emissions repairs are done at a test-and-repair or repair-only station of your choice, and BAR's Auto Shop Locator lists licensed ones. Back here within 30 calendar days, the $30 smog retest is $21.75, plus the $8.25 certificate if the car passes.
Do you test hybrids and diesels?
Hybrids, yes: they follow the same smog schedule as gas cars. For a diesel, call (760) 814-2021 to confirm we can test your diesel before you drive over; smog rules for diesels depend on the model year and weight rating.
My car was registered in another state. Do I need a smog check?
In most cases, yes: California generally requires a smog certification when a vehicle from another state is registered here for the first time. Fully electric vehicles and motorcycles are exempt. Driving a newer model? Call us to confirm what your vehicle needs.
