What is the Difference between Emissions Testing and a Smog Check?
Emissions Testing vs. Smog Check
State and local mandated emissions testing meets the EPA Tier 2 standard, while smog testing meets California's higher standard for EPA Tier 3.
How Do I Know If I Need a Smog Test?
Your DMV registration renewal notice will indicate "Smog Check Required" if your vehicle needs a smog check.
When Is a Smog Check Required?
- If you are selling a car or truck that is more than four years old
- When you register an out-of-state vehicle for the first time in California, you will need a smog check
- Every other year for vehicles that are more than six years old
When Is a Smog Check Not Required?
- 100% electric-powered vehicles do not need a smog check
- Motorcycles do not need a smog check
- Got a classic car? Vehicles that are model-year 1975 and older do not require a smog check
- Vehicles six model years and newer do not require a biennial Smog check
- Selling your car? Cars that are four model years and newer do not require a change-of-ownership Smog check
- Diesel-powered trucks that are model year 1997 and older

What Our Customers Are Saying

Inspections and Emissions, near Pasadena, CA
My 2015 Nissan Rogue was due for its Smog Check. My check engine light was on when I brought it in. I had the light checked at auto supply store and they said that the oxygen sensor was bad. Arthur looked at the printout paperwork and said that that may not be the problem. He popped the hood and he found the problem within less than a minute. One of the hoses was not connected to the engine. After another diagnostic check found that there may another issue but suggest that I drive a few miles to reset the emissions computer. After I drove the recommended miles I had the car smog check and it passed. I've brought in a number of cars we've had to Arthur. He is very honest, friendly and knowledgeable. I highly recommend anyone to bring their vehicle to this establishment. Definitely 5 stars.
