101 Express Smog

***UPDATE: We remain open through COVID-19. For your safety, we are able to offer contact-less smog checks (i.e. our technician does not need to enter your car) for vehicles model-year 2000 and newer. Our facilities are extremely well-ventilated as we pretty much work outdoors. We ask our technicians and all customers to observe social distancing precautions.

“An honest, fast, and convenient smog.”

101 Express Smog has been delivering great service since ever we opened in 2007. Our goal is to provide the most convenient option in the smog test industry. Moreover, we know that getting your smog test done can be a hassle, so swing by to get it done quickly or make an appointment for a time that is convenient for you.

We have two bays, and we are a STAR certified smog test station, which means that we can get you in and out faster than most smog test centers!
