Tips before you go
- Make sure the check engine light is off. A lit light is an automatic fail.
- Drive normally for a few days before the test; do not disconnect the battery or clear trouble codes right before.
- Emissions and safety inspection rules differ by state and county; your registration renewal notice says what your car needs.
- Bring your DMV renewal notice: it says whether the car must be tested at a STAR station.
- A "test & repair" station can also fix the car if it fails; a "test-only" station only tests.
Frequently asked questions
How much does a smog check cost in California?
Each station sets its own test price, so call ahead. California also charges an $8.25 smog certificate fee for every vehicle that passes; ask whether the quoted price includes it.
Do I need a STAR station?
Your DMV renewal notice tells you. If it says "Smog Certification Required at STAR Station", only a STAR-certified station can certify the car. Otherwise any licensed smog check station can test it.
How long is a smog certificate valid?
A passing smog certificate is valid for 90 days.
Which vehicles are exempt?
Gasoline vehicles 8 model years old or newer pay a smog abatement fee instead of testing. Electric vehicles, motorcycles and gasoline vehicles from 1975 or earlier are exempt.
