Mobile CARB testing for Davis

Davis sits at the crossroads of UC Davis research, Yolo County agriculture, and commuter-residential neighborhoods. All three generate heavy-duty diesel vehicles that fall under the CARB Clean Truck Check program. Our mobile service handles them all without requiring a cross-valley drive.

Where we dispatch in Davis

We regularly serve the I-80 commercial corridor, agricultural operations throughout Yolo County (including Woodland, Winters, and Dixon when scheduled together), residential addresses across central and east Davis, and institutional fleets when access permits.

Ag and research operations

Yolo County’s agricultural footprint is substantial, and the trucks that move the produce, specialty crops, and field equipment tied to it include a mix of modern OBD-capable rigs and older pre-2013 equipment. We bring both test types in one visit. University-affiliated research fleets and municipal vehicles also benefit from on-site testing to avoid moving specialized equipment.

Owner-operators and RV owners

Davis residential streets have their share of owner-operator trucks and heavy-duty motorhomes, and we service both at home addresses with minimal disruption. The test takes 15 to 35 minutes depending on type, and we upload compliance before leaving.
