Clean Carb
If you drive or own diesel trucks in California, following air rules is very important. The clean carb program is part of the state’s plan to lower air pollution from big trucks. It works with the HD I/M program to make sure trucks pass all clean air rules. If your truck does not pass a needed diesel emissions test, you might get fined or be stopped from driving in the state.
Our services help truck drivers, owners, and companies follow all clean truck check laws. We guide you step-by-step through the CTC check, help you understand clean truck check requirements, and give you the support you need to pass your truck emissions test. From truck smog checks to clean air inspections, we help your diesel truck stay legal and ready to go. We also provide aircheck and truck stop services.
Expert Ctc Vis and Truck Sheets
We know how important the CTC VIS (Clean Truck Check Vehicle Information System) is for your truck. This system keeps track of your test results, test dates, and CTC compliance. We help you manage your CTC VIS account and check that your truck’s info is correct. If something is wrong or missing, it can delay your clean truck check registration or cause problems with your CTC certificate.
We also give you clear and easy-to-read truck sheets for your records. These sheets show results from diesel inspections, truck emissions testing, and heavy duty truck inspections. We make sure each report is complete and correct, so you always have proof your truck passed. Whether you’re called in for a surprise HD I/M test or have a planned truck smog check, your truck sheet keeps you ready. We also provide services in Arcilla and Arlanza .
