Our ASE-certified technicians have the tools and expertise to get your vehicle in and out as quickly as possible. Our average smog check takes less than 15 minutes!

Smog checks aren’t something you should have to wait on. Tri-City Smog doesn’t require you to make an appointment before getting your car’s emissions checked! 

What Is A Smog Check?

Getting a smog check is a simple, standard procedure that tests your vehicle and its engine emissions. This test should only be performed at a licensed facility. Not only does it lower the number of pollutants in the air, but it acts as a good indicator of how well your engine is running. Your local DMV office can provide more information on the standards for your vehicle and when you’re required to bring your vehicle in for a smog test.

Why It’s Important To Get A Smog Check

These are important for measuring the number of vehicle emissions your car releases into the air. Depending on the model year, number of miles on the odometer, and laws in your state, you will have to get a smog check at designated times. In California, the California Air Resources Board (CARB) and Environmental Protection Agency (EPA) set the emissions standards. Emissions checks are also required whenever you transfer titles or bring in a car from out-of-state.

Tri-City Smog is a STAR Certified Emissions test center. We can check your vehicle, no matter what make or model. We also offer testing for diesel models, hybrids, and other vehicles.

I’ve done my cars here for the last 12 years and I love this place! They have done 3 cars and even if I fail they will do the best that they can do let me know what the problem is too fix it. Front desk is very friendly and the technician is on point ever time! Highly recommend this place to friends and family.
