Test Only means an honest test

Smog World is licensed by the California Bureau of Automotive Repair as a Test Only station (license #232568). We test your car; we don’t sell smog repairs. That means nobody here has a reason to fail your car.

Fast, by reputation

Reviewers keep timing us: under ten minutes for one regular, 15 to 20 minutes for another, about 25 minutes for a first-timer. Most people just wait on the bench out front.

If your car doesn’t pass

You get the test report showing what failed. Because we’re Test Only, you take it to a repair shop of your choice, then come back for the retest. Call us if you’re not sure what the report means.

FAQ

Smog check: common questions

Do I need an appointment?

No. Walk-ins are welcome during business hours: Monday to Friday 8 AM to 5 PM, Saturday 8 AM to 2 PM.

How long does a smog check take?

Usually 10 to 25 minutes, depending on the car and who’s ahead of you.

What should I bring?

Your car and your DMV renewal notice if you have one. The results are sent to the DMV electronically, so there’s no paperwork to mail.

How long is a smog certificate good for?

A California smog certification is valid for 90 days, so you can get it done before you renew or sell.

I just replaced my battery. Can I get a smog check?

Give it a few days of normal driving first. Disconnecting the battery or clearing a check-engine light resets the car’s self-checks, and the car may not be ready to test until they finish.
