About Smog N Go

Smog 'N Go, LLC is an emissions testing company based in the Sacramento area of Northern California. We opened our first shop in January of 2000, and currently, we have 5 shops.

Smog N Go performs more vehicle emissions tests than any other company in California.

How We are Different

Our goal from the very beginning has been to be California's #1 place for emissions testing.

The idea for Smog N Go started back in July of 1998. Jack Williams was waiting to get his wifes car to be tested. As he sat waiting for the test to be completed, Jack made a mental list of all the ways he thought the experience could be improved. A year and a half later, Smog N Go opened, implementing Jacks ideas for a better customer experience.
