What Glendale's Smog Check Requires

Glendale follows California's statewide smog check program, which tests whether your vehicle's emissions meet state standards. If you register or renew your vehicle registration in Glendale, you will need a passing smog check certificate before the California Department of Motor Vehicles (DMV) will process your registration.

The test itself is performed at a licensed smog check station, not at the DMV or city hall. A technician connects your vehicle to a machine that measures tailpipe emissions and checks your on-board diagnostic system. The whole process typically takes 30 minutes to an hour.

You do not need to schedule an appointment at most stations — you can walk in during business hours. However, some stations do accept appointments, which can save you wait time during busy periods.

Who Needs a Smog Check in Glendale

Most vehicles registered in Glendale need a smog check every two years when you renew your registration. However, some vehicles are exempt. Vehicles manufactured before 1976, electric vehicles, and certain hybrid models do not require testing. Vehicles that are only one or two years old may also be exempt during their first registration period — check your registration notice to confirm.

If you are registering a vehicle in Glendale for the first time, you will need a smog check unless it is a new vehicle or falls into an exempt category. The DMV will tell you whether your vehicle requires one when you begin the registration process.

Finding a Licensed Smog Check Station

California maintains an official list of licensed smog check stations on the Bureau of Automotive Repair (BAR) website. You can search by zip code or city name to find stations in Glendale. The search tool shows each station's address, phone number, and hours of operation.

Prices vary between stations but typically range from $30 to $70 depending on whether your vehicle is a sedan, SUV, or truck, and whether it has a diesel engine. Call ahead to ask the exact price for your vehicle type. Some stations offer discounts for seniors or low-income drivers — ask when you call.

You can also ask your regular mechanic or auto repair shop whether they perform smog checks. Many do, and testing at a shop where you already have a relationship can be convenient.

What to Bring and What Happens During the Test

Bring your vehicle registration or renewal notice, proof of ownership, and a valid photo ID. The technician will ask for your vehicle's make, model, year, and license plate number. Have your keys ready so the technician can start the engine and drive the vehicle onto the testing equipment.

The test itself has two main parts. First, the technician connects a probe to your tailpipe to measure emissions directly. Second, the machine reads your vehicle's on-board diagnostic system, which records emissions data from your engine's computer. Both readings must fall within California's limits for your vehicle to pass.

The entire process usually takes 30 to 60 minutes. You will receive a printed certificate when ready if your vehicle passes. If it fails, the station will give you a detailed report showing which emissions were out of range.

What to Do If Your Vehicle Fails

A failed smog check does not mean you cannot register your vehicle. You have several options. The most common is to have the necessary repairs made and then retest at the same station or a different one. The repair cost depends on what caused the failure — it could be as straightforward as replacing a spark plug or as involved as fixing your catalytic converter.

If the repair cost is high, you may be able to use California's Smog Check Repair information Program, which helps low-income vehicle owners pay for emissions repairs. You can also dispute the results through the Smog Check Review Program if you believe the test was performed incorrectly. Contact the Bureau of Automotive Repair for information about both programs.

If you choose to repair your vehicle, you have 30 days from the date of the failed test to retest. After 30 days, you will need to pay for a new initial test. Keep your failed certificate — you will need it to show the repair shop what needs to be fixed.

Timing and DMV Registration

Your smog check certificate is valid for 30 days from the date of the test. You must submit your registration to the DMV within that window, or the certificate will expire and you will need a new test. Plan to get your smog check at least a week before your registration renewal important date to give yourself time to handle any issues.

You can submit your registration to the DMV online through the California DMV website, by mail, or in person at a DMV office in Glendale. When you submit, you will need to provide your smog check certificate number or upload an image of the certificate itself. The DMV will verify the certificate with the testing station.

If your registration renewal notice says you need a smog check and you do not provide one, the DMV will not process your registration and your vehicle registration will expire. Driving with an expired registration can result in a traffic citation.

Cost and Payment

Smog check costs in Glendale range from $30 to $70 depending on your vehicle type. Most stations accept cash, credit cards, and debit cards. Some stations may charge a higher fee if your vehicle fails and you need to retest — ask about this when you call.

If you need emissions repairs, costs vary widely. A new oxygen sensor might cost $100 to $300, while a catalytic converter repair or replacement can cost $500 to $2,500 or more. Get a repair estimate before authorizing work, and ask whether the shop will warranty the repairs.

Frequently Asked Questions

Can I get a smog check before my registration renewal is due?

Yes, but remember that your certificate is only valid for 30 days. If you get the test too early, it will expire before you can submit your registration to the DMV. Plan to test within two weeks of your renewal important date.

What if I just moved to Glendale and need to transfer my registration?

You will need a smog check if your vehicle is subject to testing and your previous registration was from another state or county. California requires a current smog check for any vehicle transfer. Check your registration transfer notice to confirm whether one is required for your vehicle.

Do I need a smog check if I only drive my vehicle occasionally?

Yes, if your vehicle is registered in Glendale and is not exempt, you need a smog check to renew your registration regardless of how often you drive. The test measures your vehicle's emissions capability, not how much you use it.

What happens if I fail the smog check twice?

You can retest as many times as needed. There is no limit to the number of retests. However, each retest costs money and you must pass within 30 days of your first failed test, or you will need to pay for a new initial test. If repairs are expensive, contact the Smog Check Repair information Program.

Can I register my vehicle without a smog check if I plan to sell it soon?

No. You cannot register or renew registration without a passing smog check if your vehicle requires one. However, if you are selling the vehicle, the buyer will need to handle the smog check and registration in their own name.
