Mobile CARB Clean Truck Check on the Fairfield I-80 corridor
Fairfield sits between Sacramento and the Bay. We test at the yard — distribution, interstate staging, and Solano County trucks that do not have time to drive to a shop.
Why this stop is I-80, not a Sacramento clone
Solano County is a core service county. Trucks here are often staged between the Central Valley and the Bay — Vacaville warehouse land, Suisun / Cordelia ramps, and Fairfield yards off I-80 and Highway 12.
We group Fairfield with a Stockton run or a Napa / East Bay day when that saves you a separate trip. Tell us the city, count, and deadline.

Fairfield FAQ
Q: Do you only test in Fairfield city limits?
A: No. The useful unit is the I-80 / Solano corridor — Fairfield, Vacaville, Suisun, Cordelia.
Q: Can you group us with another stop?
A: Yes. Say how many trucks and the deadline. We will put you on the next I-80 day or pair you with Stockton or wine country if that is cleaner.
