How to find a smog check station near you
California's Bureau of Automotive Repair maintains an official list of smog check stations on its website at bar.ca.gov. You can search by ZIP code or city name to see every station within your area. The search tool shows you the station's address, phone number, and hours of operation.
You do not need an appointment at most stations — you can walk in during business hours. Some stations do take appointments, and a few require them. Call ahead if you want to confirm wait times or book a slot. Most smog checks take 30 minutes to an hour.
Smog check stations are not the same as your regular mechanic or oil change shop, though some repair shops do hold a smog check license. If your regular mechanic offers smog checks, you can use them. If not, the state's search tool will point you to the nearest licensed station.

What to bring to your smog check appointment
Bring your vehicle registration and a valid photo ID. The station will need your registration to pull up your vehicle's history and confirm that a smog check is due. Your ID confirms you are the owner or authorized to have the check done.
If your vehicle has failed a smog check before, bring any paperwork from that failure. This helps the technician understand what was tested and what repairs may have been made since then. If you have had recent repairs done to address smog check issues, bring those repair receipts as well.
Types of smog check stations and what they can do
California has two types of smog check stations: test-only stations and test-and-repair stations. A test-only station performs the smog check and tells you whether your vehicle passed or failed. They do not repair vehicles. A test-and-repair station can test your vehicle and, if it fails, perform repairs on site to bring it into compliance.
If your vehicle fails at a test-only station, you will need to take it to a repair shop and then return to a smog check station for a retest. If you use a test-and-repair station and fail, you can have the repairs done there and be retested at the same location. This can save time if you know your vehicle needs work.
Both types of stations are listed in the state's search tool. The listing will tell you whether a station is test-only or test-and-repair, so you can choose based on your situation.
What happens during a smog check
The technician will connect your vehicle to a diagnostic machine that reads your engine's emissions. For most vehicles, this takes about 10 to 15 minutes. The machine measures nitrogen oxides, carbon monoxide, and other pollutants to see whether your vehicle meets California's standards.
You will receive a printed report showing whether your vehicle passed or failed. If it passed, the station will submit the results to the California Department of Motor Vehicles electronically. Your registration will be updated automatically, and you do not need to do anything else.
If your vehicle failed, the report will show which emissions were out of range. You can take this report to a repair shop to help them understand what needs to be fixed. Once repairs are complete, you will need a retest at any smog check station.
Smog check requirements for different vehicle types
Most passenger vehicles registered in California need a smog check every two years. Vehicles that are eight years old or newer may be exempt in some cases, depending on when they were first registered. Diesel vehicles, motorcycles, and vehicles over 55,000 pounds have different rules.
Your registration notice will tell you whether a smog check is due. If the notice does not mention a smog check, your vehicle does not need one that year. You can also check your registration online through the DMV website to see your smog check status.
New vehicles are exempt from smog checks for their first six years of registration. After that, they follow the standard two-year cycle. If you have recently moved to California or registered a vehicle here, the DMV will tell you when your first smog check is due.
What to do if your vehicle fails the smog check
A failed smog check does not mean you cannot drive your vehicle. You can continue driving while you arrange repairs. However, you cannot renew your registration until your vehicle passes a smog check.
Take the failure report to a repair shop and ask them to diagnose the problem. Many shops can read the report and tell you what repairs are needed and what they will cost. Some repairs are straightforward and inexpensive; others may be more involved. Get a quote before authorizing work.
After repairs are complete, schedule a retest at any smog check station. You do not have to return to the same station where you failed. Once you pass, the station will submit your results to the DMV, and you can renew your registration.
Verifying a smog check station's license
Every smog check station must display a state license number on its storefront or waiting area. You can verify that a station is legitimate by searching the Bureau of Automotive Repair's license lookup tool on bar.ca.gov. Enter the station's name or license number to confirm it is currently licensed.
Be cautious of stations that do not display a license number or that cannot provide one when asked. Using an unlicensed station means your smog check results will not be accepted by the DMV, and you will have to pay for another check at a licensed station.
If you suspect a station is operating without a license or engaging in fraud, you can report it to the Bureau of Automotive Repair through their website. The BAR investigates complaints and takes action against unlicensed operators.
Frequently Asked Questions
Can I get a smog check at any repair shop?
No. Only stations licensed by the Bureau of Automotive Repair can perform smog checks that the DMV will accept. Some repair shops hold a smog check license, but not all do. Use the state's search tool to find a licensed station near you.
How much does a smog check cost?
The cost varies by station but typically ranges from $30 to $50. The state does not set a fixed price, so stations can charge different amounts. Call ahead if you want to know a specific station's price before you go.
What if I fail the smog check and cannot afford repairs?
California offers a Smog Check information Program for low-income vehicle owners. You may be able to get help paying for repairs or receive a waiver if repairs cost more than a certain amount. Contact your local air quality management district to learn about programs in your area.
Do I need to make an appointment for a smog check?
Most stations accept walk-ins during business hours, but some require or prefer appointments. Call the station ahead of time to ask about their policy and current wait times. Having an appointment can save you time, especially during busy seasons.
How long does it take to get smog check results?
If you pass, results are submitted to the DMV electronically the same day, and your registration is updated automatically within a few days. If you fail, you receive a printed report when ready that you can take to a repair shop. There is no waiting period for results.
