Four Counties, Six Stops-One Day: Keeping California Fleets CARB Clean Truck
CARB Clean Truck Check 4 OBD’s, 2 Smoke Tests (J1677 or OVI)
On September 10, 2025, our team at NorCal Carb Mobile set out on one of those days that reminds us why we do what we do. Four different businesses, four different cities, one trusty Tesla leading the way—and not once did we worry about the miles.
Our mission: keep fleets CARB Clean Truck compliant, no matter where they’re based. From the Bay to the Valley, here’s who we served—all in one weekday.
Stop 1: Delta Charter Bus, Stockton
Buses don’t just move people—they move communities. Delta Charter Bus has been a go-to in Stockton for group travel, and they can’t afford downtime. We rolled in, kept their fleet compliant, and left them ready to roll.
Stop 2: Seddon Construction, Petaluma
Construction companies run on tight schedules. If trucks aren’t compliant, projects stall. At Seddon Construction, we handled the testing on-site so their fleet stayed sharp and their jobsites stayed active.
Stop 3: I-Drill Engineering, Downtown San Francisco
Downtown traffic, zero room for error. We slid into San Francisco to meet I-Drill Engineering’s trucks where they operate. By handling compliance in the city, we saved them hours and kept their operation moving forward.
Stop 4: Sierra Asphalt, Rancho Cordova
Finishing the day in Rancho Cordova, Sierra Asphalt’s fleet was waiting. With a quick round of testing, their trucks were certified, ready for the road, and the keys were put right back where we found them.

This day sums up what NorCal Carb Mobile is all about: we come to you, when you need it, and keep your fleet compliant without the downtime. Sacramento to San Francisco, Stockton to Petaluma—no distance is too far when the job is keeping trucks on the road and California’s air clean.
