"Smog certification required"
You need a passing check before the DMV renews your registration. The station sends the result to the DMV electronically.
"STAR certified station"
Some notices require a STAR station. If yours does, confirm the station is STAR certified when it quotes you.
The renew-by date
Book a few days early. If the car fails, you'll want time for a repair and a retest.

Smog questions
How often does California require a smog check?
Most vehicles need one every two years at registration renewal, and your DMV notice says when. Gas vehicles in their eight newest model years usually pay a smog abatement fee instead.
Do I need a smog check to sell my car?
Usually, yes. The seller provides a valid smog certificate, unless the car is four or fewer model years old.
I just moved to California. Do I need one?
Most vehicles coming from out of state need a smog check before they can be registered here.
Which vehicles are exempt?
Electric vehicles, gas vehicles from 1975 and older, diesels from 1997 and older or over 14,000 lbs, and motorcycles.
What is a STAR station?
A station certified by the Bureau of Automotive Repair to meet higher performance standards. Some renewal notices require one, so check yours.
What if my car fails?
You'll need repairs and a retest. The state's Consumer Assistance Program may help eligible owners with repair costs or vehicle retirement.
How much does a smog check cost?
Each station sets its own price. Stations quote you through Lokuli, so you can compare before you go.
