At Jefferson Smog we offer you an honest, reliable, fair, and hassle-free Test Only Star Certified Smog Station with extremely high attention to service and experience... Best of all, we do it at a Fair Price, the way it should be. As one of the pioneers of Test Only smog-checks in the Inland Valley, we were one of the first ones to open a Test Only station in Murrieta...so stop by and see us...worry free!

We are happy to serve Murrieta, Temecula, Wildomar and the entire Inland Valley.
