Bring your registration renewal notice. States that require emissions testing usually print the type of test on it. In California, a notice that says “STAR station required” means only a STAR-certified station can do the check, and test-only stations check cars but do not repair them.

Good to know

How much does a smog check cost?

Prices depend on the state and the station. In California a smog check usually costs about $30–70 plus the state certificate fee; in states that run their own emissions programs the fee is often a flat amount set by the state.

What happens if my car fails the emissions test?

You get a report with the reason for the failure, and the car needs repairs before a retest. Many states give a free or discounted retest within a set number of days, and some offer repair assistance or waivers when repair costs pass a limit.
