How Do Smog Tests Work?

Have you had a vehicle smog check lately? 

According to California law, all vehicles (produced after 1976) have to complete a smog test twice a year — with a few exceptions. 

Mandatory smog checks in California keep our air clean and safe. It’s the only way to make sure that your vehicle isn’t emitting excessive pollution. And when you work with the best local mechanics here in Northern California, you’re guaranteed a fast, efficient, and cheap smog test right away. 

Why Do I Need a Smog Check?

California smog check laws might seem strict, but there’s a good reason for them. As one of the biggest and most populous states in the country, Californians drive more than anyone. So it’s important to make sure we’re keeping our air clean! 

Having a smog check done on your vehicle twice a year prevents excessive emissions, and ensures that our air stays clean and pollution-free. 

How Does It Work? 

Your smog test will be conducted in 3 parts: 

First, mechanics will visually inspect the vehicle to make sure that all emissions control devices are installed and functioning. Second, they will check that the emissions warning light is working. Finally, the car is hooked up to a testing device to get a reading from the tailpipe. 

It’s quick and cheap — and then you can get back on the road. 

Does my Vehicle Need a Smog Check? 

There are a few types of vehicles that are exempt from California smog check policy. 

Special rules apply to smog tests for: 

  • Hybrids
  • Electric cars 
  • Motorcycles
  • Trailers
  • Cars 6 years old or younger
  • Cars made before 1976

If your car doesn’t fit into any of those categories, it will need to pass a smog test at least twice a year.
