Smog check stations in Fontana are certified by the state and located throughout the city

Fontana has multiple smog check stations where you can test your vehicle. These are independent businesses certified by the California Bureau of Automotive Repair (BAR) to perform the test. You do not need an appointment at most stations — you can drive in during business hours and wait your turn, though some locations accept reservations.

The test itself takes 10 to 30 minutes depending on the station's workload and your vehicle's model year. Older vehicles (1976 and earlier) are exempt from smog checks in California. Vehicles 1977 and newer must pass every two years, or every year if the vehicle is between 6 and 10 model years old.

You can find certified stations by searching the BAR's online station locator at bar.ca.gov and entering Fontana as your city. The results show each station's address, phone number, and hours. Call ahead if you want to confirm they are open or ask about wait times.

What to bring and what the test covers

Bring your vehicle registration and a form of identification. The smog check technician will verify your vehicle's identification number (VIN) against the registration to confirm you own the vehicle being tested. Some stations also accept a bill of lading or lease agreement if you do not have the registration with you, but calling ahead to confirm is safer.

The test measures your vehicle's emissions through the onboard diagnostic (OBD) system on 1996 and newer vehicles. For older vehicles (1976–1995), the technician performs a tailpipe test that measures carbon monoxide and hydrocarbons. The test does not require you to turn off the engine or leave the vehicle — the technician handles all the equipment.

Results are transmitted to the California Department of Motor Vehicles (DMV) electronically, usually within one business day. You will receive a printed receipt at the station showing whether you passed or failed. If you pass, you can renew your vehicle registration online or at the DMV without returning to the smog station.

Cost and payment methods at Fontana stations

Smog check fees in Fontana typically range from $30 to $50 per test. The state does not set a fixed price — each certified station sets its own fee. Some stations charge slightly more for larger vehicles or diesel engines. Call the station before you go if you want to know the exact price.

Most stations accept cash, debit cards, and credit cards. A few may accept only cash, so bringing both payment methods is a safe approach. If you fail the test and need to retest after repairs, many stations offer a discounted retest fee or waive the fee entirely if you return within a set timeframe (often 30 days). Ask about this policy when you pay for your first test.

What happens if your vehicle fails the smog check

If your vehicle fails, the technician will provide a printed report showing which emissions standards were not met. This report tells you what repairs are needed. You have 30 days from the test date to repair your vehicle and retest at any certified smog check station in California — not just in Fontana.

You do not have to return to the same station. Some drivers choose a different station for the retest, or they may find a station with a lower retest fee. Keep the failure report and bring it with you when you retest, as it helps the technician understand what was repaired.

If you repair your vehicle and it still fails the retest, you may be may be able to access for a Smog Check Abatement Program or a Consumer information Program (CAP) rebate. These programs help pay for repairs on vehicles that repeatedly fail. Contact the BAR or your local Fontana city offices to learn whether you meet the income and vehicle age requirements.

Scheduling and wait times at Fontana locations

Walk-in service is available at most Fontana smog check stations during their posted hours. Wait times vary by time of day and day of week. Early mornings on weekdays are usually less crowded than afternoons or weekends. If you want to avoid waiting, call the station and ask about their busiest hours, or ask whether they take reservations.

Some stations in Fontana use online booking systems where you can reserve a time slot. Check the station's website or call to see if this option is available. Even with a reservation, arrive 5 to 10 minutes early so the technician can verify your registration and vehicle information.

Retesting after repairs and registration renewal

After you repair your vehicle and pass the retest, the results are sent to the DMV automatically. You can then renew your vehicle registration online through the DMV website, by mail, or in person at a DMV office. You do not need to bring the smog check receipt to the DMV — the agency receives the results electronically.

If you registered your vehicle before the smog check was due, you may have received a notice from the DMV saying your registration cannot be renewed until you pass a smog check. Once you pass, that hold is lifted and you can complete your registration renewal. If you have questions about your registration status, call the DMV at 1-800-777-0133.

Frequently Asked Questions

Can I get a smog check waiver in Fontana?

Waivers are rare and only issued by the BAR in specific cases, such as when a vehicle has been repaired multiple times for the same failure and still does not pass. You cannot request a waiver from a smog check station. If you believe your vehicle qualifies, contact the BAR directly at bar.ca.gov or call 1-888-225-5227 to discuss your situation.

What if I just moved to Fontana and my vehicle is registered in another state?

You must register your vehicle in California within 20 days of moving. Once you have a California registration, you will need a smog check before you can renew it. If your vehicle is still registered out of state, you cannot get a smog check in Fontana — the technician will verify your registration matches the vehicle's VIN.

Do I need a smog check if I am selling my vehicle in Fontana?

Yes, if the vehicle is 1977 or newer and the registration is current. The seller must provide a smog check certificate dated within 90 days of the sale. If the registration has expired, the vehicle must pass a smog check before it can be transferred to the new owner. The buyer and seller can agree on who pays for the test.

How long does a smog check certificate last?

A passing smog check is valid for 30 days. You must renew your vehicle registration before the 30 days expire, or the certificate becomes invalid. If you do not renew your registration in time, you will need another smog check to complete the renewal.

Can I get a smog check for a vehicle that does not start?

No. The vehicle must be in working condition and able to run. If your vehicle does not start, have it repaired first, then take it to a smog check station. Some stations may refuse to test a vehicle that appears unsafe to drive.
