Smog check questions, answered.
A quick primer before you head to the station.
How much does a smog check cost in Los Angeles?
Smog check prices vary depending on your vehicle's year and the station. Pre-1996 vehicles generally cost less, while newer vehicles with OBD-II systems may have different pricing. Check individual station pricing above for exact rates at each location.
Do I need an appointment for a smog check?
Most stations accept walk-ins, though some prefer appointments during busy hours. Contact the station directly or visit them to confirm. The smog check process typically takes 15-30 minutes.
What do I need to bring for a smog check?
Most stations simply need your vehicle. Make sure your check engine light is off and your vehicle has been driven recently to ensure the emissions system is ready for testing. The station will guide you through the rest of the process.
How often do I need a smog check in California?
In California, most vehicles require a smog check every 2 years when renewing registration. New vehicles are exempt for the first 8 years. Diesel vehicles 1998+ over 14,000 lbs require annual checks. Check your registration renewal notice for your specific requirement.
What happens if my vehicle fails the smog check?
If your vehicle fails, the technician will provide a diagnostic report explaining the issues. You'll need to get the necessary repairs done and return for a re-test. Some stations offer free re-tests within a certain timeframe after the initial test.
