Seaport facilities must verify Clean Truck Check compliance at entry or log non-compliant trucks (CARB). Tester supply here is small for the truck volume, so many port truckers use mobile testers from nearby cities. Alameda County includes the Port of Oakland and the I-880 industrial corridor (Hayward, San Leandro, Fremont). ## Cost Typical published prices in California: OBD test $50–$135 per vehicle; smoke opacity test $190–$200. Prices are set by each tester. ## Frequently asked questions ### How many Clean Truck Check testers are in Oakland?
