What Long Beach requires for smog check

Long Beach follows California's statewide smog check program, which requires most vehicles to pass an emissions test every two years. Your vehicle needs a smog check before you can register it with the California Department of Motor Vehicles (DMV), and you must pass before your registration expires. The test measures how much pollution your car's exhaust produces — if it exceeds state limits, you cannot register the vehicle until repairs are made and it passes a retest.

Not every vehicle needs a smog check. Vehicles registered in California for less than four years, electric vehicles, and some motorcycles are exempt. Vehicles that are 1975 or older are also exempt. If you are unsure whether your car needs one, the DMV website lets you enter your vehicle information to check.

Long Beach is in an area designated as a nonattainment zone for air quality, which means the region does not consistently meet federal air quality standards. This is why the smog check program exists here — it is a tool to reduce the emissions that contribute to air pollution in the area.

Key Takeaways

  • Most vehicles registered in California for four years or longer must pass a smog check every two years before registration renewal.
  • You can only get a smog check at a California-licensed smog check station, not at the DMV or a general repair shop without certification.
  • The test costs between $30 and $70 depending on the station and your vehicle type, and you pay at the time of the test.
  • If your vehicle fails, you have 30 days to make repairs and return to any smog check station for a retest at no additional charge.
  • You must bring your vehicle registration and a valid ID to the smog check station.

Finding a smog check station in Long Beach

The California Bureau of Automotive Repair maintains an official list of licensed smog check stations. You can search by zip code on their website (bar.ca.gov) to find stations near you in Long Beach. The search shows the station's address, phone number, and hours. Call ahead to confirm they are open and can test your vehicle type, since some stations specialize in certain vehicle categories.

You can also search online for "smog check Long Beach" to find local options, but verify that any station you choose is licensed by the state. An unlicensed station cannot issue a valid smog check certificate, and you would have to pay again at a licensed station.

Many independent repair shops, dealerships, and dedicated smog check stations offer the service. Some stations are faster than others — a typical test takes 15 to 30 minutes, though you may wait if the station is busy. Some stations offer appointments, which can save you time.

What happens during the smog check test

When you arrive at the station, bring your vehicle registration and a valid ID. The technician will connect your vehicle to an emissions testing machine, which measures the levels of nitrogen oxides, carbon monoxide, and other pollutants in your exhaust. The test itself takes only a few minutes.

For most vehicles, the test is non-invasive — the machine plugs into your vehicle's onboard diagnostic port, usually located under the steering wheel. The technician does not need to take your car apart or perform any work during the test. For some older vehicles without a diagnostic port, a different testing procedure may be used.

After the test, you receive a result on the spot. If you pass, the station issues a smog check certificate (also called a STAR certificate) electronically to the DMV. You can then register your vehicle online, by mail, or in person at a DMV office. If you fail, the station gives you a copy of the test results showing which emissions exceeded the limit.

What to do if your vehicle fails the smog check

A failed smog check means your vehicle's emissions are above California's limits. You have 30 days from the test date to have repairs made and return for a retest. You do not pay for the retest — the 30-day retest is free at any licensed smog check station.

The test results show which emissions failed, but they do not diagnose the specific problem. Common causes include a faulty oxygen sensor, a malfunctioning catalytic converter, a clogged air filter, or an engine problem. Take the test results to a repair shop and ask them to diagnose the issue. Some repair shops can look at the results and give you an estimate before you authorize work.

If repairs cost more than a certain amount (the threshold varies by vehicle age and type), you may be able to claim a smog check repair cost waiver. Contact the Bureau of Automotive Repair or ask your repair shop whether you may have access to. The waiver allows you to register your vehicle even if it does not pass the retest, but only after you have made a good-faith repair attempt and documented the cost.

Smog check costs and what affects the price

A smog check test costs between $30 and $70 at most Long Beach stations. The exact price depends on the station and your vehicle type. Hybrid vehicles, motorcycles, and vehicles with diesel engines sometimes cost more or less than standard gasoline cars. Call the station before you go to confirm the price for your specific vehicle.

The cost covers only the test itself. If you fail and need repairs, those costs are separate and depend on what is wrong with your vehicle. A new oxygen sensor might cost $100 to $300 installed, while a catalytic converter replacement can cost $400 to $2,500 or more. Get a repair estimate before authorizing work.

Some stations offer package deals or discounts if you also need other services like an oil change or inspection. Ask about any current promotions when you call.

How to register your vehicle after passing smog check

Once you pass the smog check, the station sends the certificate electronically to the DMV. You do not need to pick up a paper certificate or bring anything to the DMV. You can renew your registration online through the DMV website, by mail, or in person at a DMV office in Long Beach.

Online renewal is the fastest option if you have a valid email address and a credit or debit card. The DMV website (dmv.ca.gov) lets you renew registration, pay the renewal fee, and receive your new registration documents by mail within a few days. By mail, you can send in the renewal notice that came with your registration, along with payment. In person, visit any DMV office with your vehicle registration and ID.

Your registration renewal fee depends on your vehicle's value and age. The DMV notice you received in the mail shows the exact amount due. You must renew before your current registration expires, or you risk a citation if you drive with expired registration.

Smog check requirements for different vehicle types

Most gasoline-powered cars, trucks, and SUVs registered in California for four years or longer need a smog check every two years. Diesel vehicles follow the same schedule. Hybrid vehicles need a smog check, though some stations may charge differently for them.

Motorcycles registered in California need a smog check every two years if they were first registered after 1975 and have an engine larger than 50 cubic centimeters. Smaller motorcycles and mopeds are exempt. Electric motorcycles do not need a smog check.

Vehicles registered for less than four years are exempt from smog checks during that period. Once your vehicle reaches four years old, it must pass a smog check before the next registration renewal. Vehicles manufactured in 1975 or earlier do not need a smog check, regardless of how long they have been registered.

Frequently Asked Questions

Can I get a smog check if my vehicle has a check engine light on?

Most smog check stations will not test a vehicle with the check engine light illuminated, because the light indicates a diagnostic trouble code that could affect the test results. You need to have the problem diagnosed and repaired first, then clear the code before the smog check. A repair shop can do this, or you can clear it yourself with a diagnostic scanner if you have access to one.

How long does a smog check certificate last?

A smog check certificate is valid for 30 days from the test date. You must register your vehicle with the DMV within that 30-day window, or the certificate expires and you will need a new smog check. If you pass the test but do not register within 30 days, you have to pay for another test.

What if I move out of California after getting a smog check?

If you register your vehicle in another state, you do not need to worry about California's smog check. However, if you plan to keep your California registration while living elsewhere temporarily, you still need to renew registration on schedule, which means you still need a smog check every two years.

Can I get a smog check for a vehicle I am about to sell?

Yes, you can get a smog check before selling your vehicle. Some buyers request a recent smog check certificate as proof the vehicle meets emissions standards. The certificate is valid for 30 days, so time it close to the sale if possible. The seller is responsible for providing a smog check in California, not the buyer.

What if the smog check station made an error on my test?

If you believe the test was performed incorrectly or the results are wrong, you can request a retest at the same station or a different licensed station. You pay for the retest. If you believe the station is not following state rules, you can file a complaint with the Bureau of Automotive Repair through their website.
