About

We are a CARB-accredited mobile Clean Truck Check service, specializing in diesel emissions compliance testing for heavy-duty diesel vehicles (trucks and RVs) with a Gross Vehicle Weight Rating (GVWR) over 14,000 pounds. As a fully mobile service, we bring our Clean Truck Check directly to you, saving you time and effort compared to visiting a testing facility. Proudly serving all of Southern California, we’re equipped to perform smog checks on fleets of any size, from a single vehicle to multiple trucks or RVs. With over two decades of combined experience, our licensed testers ensure your vehicle’s information is submitted to the CARB database for compliance, so you can stay on the road with confidence.
