CARB Clean Truck Check testing across the entire Bay Area

The SF Bay Area is one of the densest diesel fleet markets in California. Drayage trucks moving containers off the Port of Oakland, distribution fleets running the I-880 corridor, construction rigs working high-rises in San Francisco and tech campuses in San Jose, last-mile delivery vans crisscrossing the Peninsula, transit and municipal fleets across all nine counties. Every one of those vehicles is subject to CARB’s Clean Truck Check program, and most owners would rather not lose a half-day driving a truck to a brick-and-mortar test station.

We come to you instead. Our credentialed testers dispatch across the Bay Area to perform OBD and OVI testing on-site, upload results during the visit, and clear DMV holds the same business day for eligible engines. Whether you operate a single owner-operator rig or run a 50-truck fleet from a yard in Hayward, the call is the same.

Where we dispatch in the Bay Area

We regularly run mobile CARB testing in Oakland, Alameda, Berkeley, Emeryville, Hayward, San Leandro, Fremont, Union City, Newark, Castro Valley, Pleasanton, Livermore, Concord, Walnut Creek, Martinez, Richmond, San Jose, Milpitas, Santa Clara, Sunnyvale, Mountain View, Campbell, San Francisco, Daly City, South San Francisco, San Bruno, San Mateo, Redwood City, Vallejo, Napa, San Rafael, Novato, and Petaluma. If your city or yard is not on this list, call us. We almost certainly cover it.

What we test

OBD testing for diesel engines model year 2013 and newer, OVI opacity testing for older engines, and the full CARB Clean Truck Check workflow for trucks above 14,000 pounds GVWR. We also handle BAR-OIS testing for diesels under that threshold and bring the right equipment for both fleet yards and residential-driveway visits.

Frequently asked questions

Do you actually serve the entire Bay Area or just one part of it?
We dispatch across all nine Bay Area counties (San Francisco, Alameda, Contra Costa, San Mateo, Santa Clara, Marin, Sonoma, Napa, and Solano). East Bay and South Bay get the most volume, but we routinely cover the Peninsula, San Francisco proper, and the North Bay too. Tell us your zip and we will confirm scheduling.
How fast can you get a tester to my Bay Area yard?
Most Bay Area requests are scheduled within 24 to 48 hours. We can often do same-day visits when called before 10 a.m., especially in the East Bay and South Bay where dispatch density is highest.
Are your tests valid for both CARB Clean Truck Check and DMV registration holds?
Yes. We are credentialed for both OBD (model year 2013 and newer engines) and OVI opacity testing (older engines). On OBD passes, results upload electronically and CARB releases compliance to DMV the same business day in most cases.
Do you handle Port of Oakland drayage trucks?
Yes, we test drayage rigs regularly across West Oakland, the Outer Harbor, and the Hegenberger and Edgewater corridors. We can come to the yard between turns or schedule around your dispatch window.
Can you test at a Silicon Valley campus or distribution center?
Yes. We service tech-industry distribution centers, data-center logistics fleets, and contractor yards across San Jose, Milpitas, Sunnyvale, Fremont, and Santa Clara. We bring our own equipment, parking flat surface and a charged battery is all we need.
Do you charge extra for Bay Area service compared to Sacramento?
Pricing is consistent across our coverage area. Mobile fees may apply for very low truck counts at distant locations. For fleets of three or more rigs at a single Bay Area address, we treat the visit the same as a Sacramento dispatch.
Do you serve BAAQMD-regulated fleets?
Yes. CARB Clean Truck Check applies statewide, but Bay Area fleets often have additional BAAQMD compliance considerations. We focus on the CARB testing piece and can refer trusted partners for broader BAAQMD compliance support if needed.
How do I book a Bay Area test?
