The closest CARB-credentialed Clean Truck Check tester is MEJIA'S TRANSPORT LLC in Frederick, Maryland — about 63 miles away (straight-line). Smart CTC tests over the truck’s OBD port from anywhere, with no drive and no appointment.
Washington sits on I-66, US-211, US-340, US-522, VA-229 and VA-231. Trucks running these routes into California fall under CARB’s Clean Truck Check — Smart CTC lets them test remotely without leaving the road.
