Licensed and Certified Smog Check Center

Specializing in Smog Test Services

FasTest Smog CentersMost vehicles in the state of California are required to pass a smog test every two years for their registration renewal. If you received your renewal notice and found that you are required to get a smog test from a STAR-certified station, head over to FasTest Smog Center, formerly Walnut Creek Test Only Center. We specialize in accurate and efficient smog tests. Our Licensed Technicians have the necessary skills and technical know-how to perform fast and accurate emission checks on all types of vehicles. With over a decade of experience in the automotive industry, we always strive for a 5-star worthy emission test that is fast and easy.


Cutting-Edge Equipment and Knowledgeable Staff

FasTest Smog CentersOur knowledgeable technicians provide smog check services for all makes and models, including cars, trucks, SUVs, diesels, motor homes, exotic vehicles, and even gross polluters. Using our state-of the-art Data Acquisition Device (DAD) System or, when required, our BAR-97 Emission Inspection System (EIS), we can do highly accurate and safe visual, functional, or tailpipe emission tests on your vehicle. Our smog check stations use cutting-edge dynometers for Acceleration Simulation Mode, which simulates actual driving conditions and allows for a more precise testing for the three most harmful pollutants emitted by motor vehicles: Carbon Monoxide (CO), Hydrocarbon (HC), and Nitrogen Oxide (NOx). Clean vehicles help to reduce airborne pollutants for all Californians and beyond.
