Emissions Edge is a mobile clean-truck and emissions testing service for heavy-duty diesel semi-trucks. We’re CARB certified and fully mobile — we bring the equipment and the credentials directly to your truck, anywhere in California.

​

California requires diesel trucks over 14,000 lbs to be tested multiple times a year under the Clean Truck Check program, and that cadence is increasing. Instead of pulling a truck off the road to sit in a shop, we come to your yard, terminal, or job site, run the test in about 15–20 minutes, and upload the results straight to CARB’s compliance database.

​

For owner-operators and fleets alike, that means less downtime, faster compliance, and one less thing to worry about.
