ST Pros provides mobile Clean Air Check testing throughout California's Central Valley, serving commercial fleets, semi-trucks, and RVs within approximately a 75-mile radius of our home base in Clovis, CA. If you operate commercial vehicles — or own a semi-truck or RV — in the Central Valley, there's a good chance we can come directly to your location.
Our service area covers some of California's most active freight, agricultural, and logistics corridors — communities where commercial vehicle compliance is a daily operational concern for fleet managers and owner-operators alike. We built our mobile testing service specifically for these markets.
