What Long Beach requires for smog check

Long Beach follows California's statewide smog check program, which means your vehicle must pass an emissions test before you can register it or renew your registration. The test measures what comes out of your tailpipe — specifically nitrogen oxides, particulate matter, and hydrocarbons — to confirm your car meets state air quality standards.

You need a smog check if you own a vehicle registered in California and it is due for registration renewal. The test is required every two years for most cars, though some newer vehicles (typically 2000 and newer) may be exempt in their first four years. Diesel vehicles, motorcycles, and vehicles over 30 years old have different rules or are exempt entirely.

Long Beach is in Los Angeles County, which is part of the South Coast Air Quality Management District (SCAQMD). This means the emissions standards are the same as the rest of Southern California — there are no separate Long Beach-only rules. You can get your smog check at any California-licensed smog check station, whether it is in Long Beach or anywhere else in the state.

Key Takeaways

  • Long Beach vehicles must pass a smog check every two years as part of California's statewide emissions program, with some newer and older vehicles exempt.
  • You can get tested at any licensed smog check station in California, not just in Long Beach, and the test takes about 10 to 15 minutes.
  • The test costs between $30 and $50 depending on the station, and you will receive a certificate when ready if you pass.
  • If your vehicle fails, you have 30 days to repair it and retest at no additional cost at the same station.
  • You cannot register or renew your registration without a passing smog check certificate, so plan ahead before your registration expires.

Finding a smog check station in Long Beach

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 near you in Long Beach. The list shows the station's address, phone number, and hours of operation.

Most smog check stations are independent repair shops, gas stations with service bays, or larger chains like Jiffy Lube or Firestone. Call ahead to confirm they are open and ask how long the wait is — some stations get busy during the last week of the month when people rush to renew registrations. Many stations do not require an appointment, but a few do.

You do not have to use a station in Long Beach itself. If you find a station with shorter hours or a shorter wait in a nearby city, you can go there instead. The smog check certificate is valid statewide and works for registration renewal anywhere in California.

What happens during the smog check test

When you arrive at the station, bring your vehicle registration and a valid photo ID. The technician will enter your vehicle information into the state's Smog Check Information System (SCIS) before testing begins. This step confirms your vehicle is actually due for a smog check and is not exempt.

The actual test takes 10 to 15 minutes. For most vehicles, the technician connects a probe to your tailpipe and runs the engine through a series of speeds while measuring emissions. The machine records whether your vehicle passes or fails based on California's emission standards for your vehicle's year and type.

If you pass, you receive a certificate when ready — either printed on paper or sent electronically to the state system. You can then use this certificate to renew your registration online, by mail, or in person at the Department of Motor Vehicles (DMV). If you fail, the technician will give you a report showing which emissions exceeded the limit.

What to do if your vehicle fails the smog check

A failed smog check means your vehicle is producing too much pollution and needs repairs before it can be registered. The test report will tell you which emissions failed — usually nitrogen oxides, hydrocarbons, or particulate matter — but it does not tell you which part is broken.

Common reasons for failure include a faulty oxygen sensor, a malfunctioning catalytic converter, a bad spark plug or ignition coil, or a fuel system leak. You will need to take your vehicle to a repair shop to diagnose the problem. Many shops can read the diagnostic trouble codes from your vehicle's computer to narrow down the cause.

California law gives you 30 days from the test date to repair your vehicle and retest at the same station at no additional charge. If you retest within 30 days and pass, you pay only the standard smog check fee again — not a second full fee. If you wait longer than 30 days, you must pay the full fee again at a new station.

Cost and timing for Long Beach smog checks

A smog check in Long Beach costs between $30 and $50, depending on the station. Some stations charge a flat rate; others charge slightly more for diesel vehicles or older vehicles. This is the only fee you should pay for the test itself — if a station tries to charge you extra for entering your information into the state system or for the certificate, that is not standard practice.

Plan to get your smog check at least two weeks before your registration expires. This gives you time to retest if you fail, and it prevents you from driving an unregistered vehicle. If your registration has already expired, you can still get a smog check, but you cannot legally drive the vehicle to the station — you will need to have it towed or transported on a flatbed.

The smog check certificate is valid for 30 days. If you pass the test but do not renew your registration within 30 days, you will need a new smog check. This is rare, but it matters if you are planning to wait a long time between passing the test and renewing your registration.

How to renew your registration after passing smog check

Once you have a passing smog check certificate, you can renew your registration through the California DMV. You can do this online at dmv.ca.gov, by mail, or in person at a DMV office in Long Beach. If you pass the smog check and the station sends the results electronically to the state system (which most do now), the DMV will see your passing result automatically — you do not need to bring the paper certificate.

If your station gave you only a paper certificate and did not send results electronically, bring the certificate with you when you renew. The DMV will not process your renewal without proof of a passing smog check.

Registration renewal fees vary based on your vehicle's value and age. The smog check fee itself is separate from the registration renewal fee — you pay both. The DMV website shows the exact amount for your vehicle once you enter your license plate number.

Vehicles exempt from smog check in Long Beach

Not every vehicle in Long Beach needs a smog check. Vehicles that are 30 years old or older are permanently exempt. Motorcycles are exempt. Vehicles registered as non-operational or for off-road use only do not need a smog check.

Newer vehicles — typically 2000 and newer — are exempt from smog check for their first four years of registration. After that, they enter the regular two-year cycle. Some electric vehicles and plug-in hybrids may have different requirements depending on their registration type.

If you are unsure whether your vehicle is exempt, enter your license plate number on the DMV website or call the Bureau of Automotive Repair at 1-800-952-5210. They can tell you whether your specific vehicle needs a smog check.

Frequently Asked Questions

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

No. If your check engine light is illuminated, the smog check station will not test your vehicle. The light indicates a diagnostic trouble code is stored in your vehicle's computer, and the state requires that code to be cleared before testing. You must take your vehicle to a repair shop to diagnose and fix the problem first, then clear the code before returning to the smog check station.

What if I just moved to Long Beach from another state?

If you are registering a vehicle in California for the first time, you will need a smog check before the DMV will issue a California registration. The vehicle must pass a test at a California-licensed station. Vehicles from other states are not exempt, even if they passed emissions testing in their previous state.

How long does the smog check certificate stay valid?

The certificate is valid for 30 days from the test date. You must renew your registration within that window, or you will need a new smog check. If you pass the test but do not renew registration when ready, plan to get retested before the 30 days expire.

Can I get a smog check waiver if my vehicle keeps failing?

California has a Smog Check Referee Program for vehicles that fail repeatedly despite repairs. If your vehicle has failed twice in a row at a regular station, you can take it to a Smog Check Referee station for a second opinion. If the Referee station confirms the failure, you may be issued a waiver that lets you register the vehicle anyway. This is a last resort and requires documentation of your repair attempts.

Do I need a smog check to sell my car in Long Beach?

No smog check is required to sell a used vehicle in California. However, the buyer will need a passing smog check before they can register it in their name. If you are selling a vehicle that is due for a smog check, it is often easier to get it tested before the sale so the buyer does not have to deal with it.
