Keeping the air clean is important, especially with heavy-duty trucks. At our shop, we help truck owners meet all Clean Truck Check (CTC) and HD I/M (Heavy-Duty Inspection and Maintenance) program rules. A clean air test is more than just a fast check.

Our clean air inspections check for too much smoke or pollution from diesel engines. Whether you own one truck or many, regular clean truck check testing helps keep your trucks in line with the rules. We make it simple to sign up and finish your clean air test, helping you avoid trouble and stay on the road. You can count on us to guide you every step of the way—from sign-up to testing to getting your certificate. We also provide truck emissions inspection and diesel truck smog check services.

Certified Clean Truck Registry and CTC Certificate Trucking Requirements

California has new rules for diesel trucks. To be allowed to drive, your truck must be in the Certified Clean Truck Registry and have a CTC certificate. This certificate proves your truck passed the emissions test. Some people call this test the truck smog check or diesel emissions test. Without this certificate, your truck could get fined or not be allowed to work in certain places.

To get your truck in the clean truck registry, you must do regular HD I/M tests and follow all clean truck check rules. These rules are for most diesel trucks over 14,000 pounds. We help truck owners learn how to sign up for the HD I/M program, how to get a clean truck check certificate, and how to stay in line with the clean truck check rules. Our team is ready to help you through every step—from CTC registration to truck inspection. We also provide services in Blythe and Calimesa .

Expert CTC VIS and Truck Sheets

We help with your CTC VIS (Vehicle Information Submission) and truck sheets. These are both important for the Clean Truck Check process. The CTC VIS must be correct and up to date so your truck is listed the right way in the system. If the info is wrong, you might not pass your clean truck check or miss a deadline. We help you fill in and fix your truck’s info to follow the clean air inspection rules.

Truck sheets are records that show details about your truck’s emissions system, testing history, and any service done. These sheets are checked during truck inspections and need to be up to date. We help you keep these records organized and complete so you’re ready for any heavy-duty vehicle inspection. With our help, your truck will be ready to pass every test and stay on the road. We also provide heavy duty truck inspection and commercial truck emissions testing services.
