OC CLEAN LINK our new telematics-based testing now available!
At OC Clean Truck, we are committed to offering dependable (CARB) CLEAN TRUCK CHECK INSPECTIONS to ensure your vehicle adheres to California's emissions standards. We are proud to be among the initial companies in California to receive recognition from CARB as an approved tester. Our objective is to contribute to cleaner air by assisting you in maintaining your vehicle's compliance with environmental regulations. We provide both in-person testing and entirely remote telematics-based testing options.






We now provide fully remote testing capabilities. Our OC Clean Link telematics module can be programmed and installed in Orange County, or it can be pre-programmed and shipped anywhere in California for immediate installation. This module enables us to remotely test your trucks while they are in operation, eliminating the need for in-person appointments and minimizing downtime.
OC Clean Truck has been a leader in the diesel fleet management industry for over 15 years. All of our technicians hold Master Technician Certifications and have performed thousands of smog checks, ensuring your vehicles consistently meet all state regulatory requirements.
We use state-of-the-art equipment to conduct our smog checks. Our equipment is regularly maintained and updated to ensure accurate readings. With multiple machines, we are able to handle large fleets.
