About NorCal Calibration — Sacramento Mobile CARB Testing
Dedicated exclusively to mobile Clean Truck Check (CTC) testing and diesel emissions compliance across Sacramento and the entire North Valley.
Sacramento Based. Built to Keep Northern California Trucking Moving.
NorCal Calibration was founded with a single mission: to eliminate the headaches, wasted driver hours, and costly downtime associated with mandatory California Air Resources Board (CARB) emissions compliance.
Rather than requiring drivers to navigate heavy semi trucks through crowded brick-and-mortar inspection lanes, our fully equipped mobile testing units bring certified OBD diagnostic scanners directly to your fleet yard, truck stop, job site, or residential parking space.
