We remain open. For your safety, we are able to offer contact-less smog checks (i.e. our technician does not need to drive or operate your car) for vehicles model-year 2000 and newer. We ask our technicians and all customers to observe strict social distancing precautions.
101 Express Smog has been delivering great service since ever we opened. Our goal is to take the hassle out of the process by providing quick and honest smog testing at our Petaluma location. So swing by today or make an appointment for a time that is convenient for you.
