How a visit works
Call first
to confirm.
Approve the estimate
before the inspection starts.
Inspection and report
You get a vehicle inspection report showing whether the vehicle passed, plus any open safety recalls.

If it fails
Emissions repairs are done at a test-and-repair or repair-only station of your choice; BAR's Auto Shop Locator lists licensed ones. We're test-only and don't repair. Once the work is done, the $30 smog retest applies within 30 calendar days: $21.75, plus the $8.25 certificate on a pass. If the check engine light is on, a vehicle will not pass, so make sure it's off before you return.
Makes we test
Lexus, Toyota and Honda top our Magnolia St job photos, but every make gets the same state test. See the brand list on our vehicles we smog check page.
