Who We Are

Air Compliance Testing (ACT) was built around one goal: making California Clean Truck Check compliance testing accessible, convenient, and fleet-friendly. ACT is a mobile testing provider, which means ACT comes directly to the customer — to the fleet yard, the business location, or wherever qualifying vehicles are located.

ACT focuses exclusively on the California commercial trucking market, serving owner-operators running a single truck as well as fleet operators managing dozens of vehicles. ACT understands the operational pressure that comes with CARB compliance deadlines and has designed its scheduling process to minimize vehicle downtime.

Rather than requiring customers to coordinate trips to an off-site testing facility, ACT brings credentialed technicians directly to the customer's location. Mobile on-site testing means trucks spend less time off the road and fleet managers spend less time coordinating logistics.

Credentialed Technicians. Professional Testing.

ACT employs credentialed technicians qualified to perform California Clean Truck Check testing. Every ACT tester is trained on current CARB program requirements and the applicable OBD and emissions inspection protocols used in the Clean Truck Check program. Customers can trust that testing is performed by qualified professionals who understand both the technical requirements and the operational needs of working fleets.
