California ended its smog check requirement for most vehicles in 2024

California stopped requiring smog checks for most passenger vehicles starting in 2024. If your car is a 1975 model or newer and you live in one of California's air quality regions, you no longer need to get a smog inspection before you renew your vehicle registration. This change affects millions of vehicle owners across the state and removes a step that used to be required every two years.

The state made this shift because vehicle emissions have dropped significantly over the past two decades. Modern cars produce far less pollution than older models, and the air quality in most of California has improved enough that the regular testing was no longer necessary to meet federal clean air standards. However, some vehicles and some situations still require smog checks, so it is important to know whether your car falls into that category.

Key Takeaways

  • Most passenger vehicles registered in California no longer need smog checks, but heavy-duty trucks, motorcycles, and vehicles registered before 1975 are still subject to testing requirements.
  • If you are buying a used car in California, the seller must still provide a smog inspection report from within the past 30 days, even though owners no longer need one for registration renewal.
  • Vehicles that fail a smog check or have been modified may still be required to undergo testing depending on the specific circumstances and your vehicle's age.
  • You can renew your vehicle registration online or by mail without scheduling a smog test, which saves time and money compared to the old process.

Which vehicles still need smog checks

Even though the requirement has been removed for most cars, certain vehicle types still need smog inspections. Heavy-duty trucks, motorcycles, and any vehicle registered before 1975 must still pass a smog check. If you own one of these vehicles, you will still need to schedule an inspection at a Bureau of Automotive Repair (BAR) certified smog station before you renew your registration.

Vehicles that have been modified or that previously failed a smog check may also face ongoing testing requirements. If your car was flagged for emissions problems in the past, California may require you to continue testing until the issue is resolved. The specific rules depend on your vehicle's history and the type of modification, so if you are unsure whether your car still needs testing, you can check your registration renewal notice or contact your local Department of Motor Vehicles office.

Buying and selling a used car still involves a smog report

Even though you no longer need a smog check to renew your registration, the smog inspection requirement did not disappear entirely. When you buy a used car in California, the seller must provide you with a smog inspection report dated within the past 30 days. This report shows that the vehicle met emissions standards at the time of sale, and you will need it to complete the registration transfer.

If you are selling a used car, you are responsible for obtaining this report before the sale. You can get it from any BAR-certified smog station, and the cost varies but typically ranges from $30 to $50. The report is valid for 30 days, so you should time the inspection close to when you expect to sell the vehicle. Private sales, dealer sales, and sales between family members all require this report, with very few exceptions.

How to renew your registration without a smog check

Renewing your vehicle registration is now simpler for most California drivers. You can renew online through the California Department of Motor Vehicles website, by mail, or in person at a DMV office. When you renew online or by mail, you will not see any smog check requirement on your renewal notice. You straightforward pay the registration fee and submit your renewal, and there is no need to visit a smog station first.

If you do receive a renewal notice that mentions a smog check, read it carefully to see whether an exception applies to your vehicle. The notice will specify if your car is one of the types that still requires testing. You can also call your local DMV office or check the DMV website to confirm whether your specific vehicle needs a smog inspection before you renew.

What happens if your vehicle was previously flagged for emissions

Some vehicles may still be subject to smog checks even though they are newer than 1975. If your car was previously flagged for high emissions or failed a smog test, California may require you to continue testing for a set period. This is called the Smog Check Referee Program, and it applies to vehicles that did not meet emissions standards in the past.

If you are in this situation, your registration renewal notice will tell you that a smog check is still required. You will need to take your vehicle to a BAR-certified smog station and pass the inspection before you can renew. Once you pass the test, you may be released from the program, though the exact timeline depends on your vehicle's history and the reason it was flagged. If you are unsure whether your vehicle is still under this requirement, the renewal notice is your clearest source of information.

Finding a smog check station if you still need one

If your vehicle still requires a smog check, you can find a certified station through the Bureau of Automotive Repair website or by searching for "smog check stations near me" online. Not all repair shops perform smog checks, so it is important to confirm that the station you choose is BAR-certified. The certification means the station meets state standards and uses approved testing equipment.

Smog check costs vary by location and vehicle type, but you can expect to pay between $30 and $70 for a basic inspection. Some stations charge more for vehicles that require additional testing or for vehicles that have been modified. Call ahead to ask about pricing and whether you need to make an appointment, as wait times can vary depending on the time of year and how busy the station is.
