California Clean Truck Check (CTC)

CARB's Clean Truck Check enforcement is coming in 2025. If you are a fleet owner, make sure that your fleet is registered and compliant by then. If you are a smog check center, consider adding Heavy Duty testing services to your business in advance of the enforcement coming into effect! To get started, choose from one of our equipment bundles below. For independent mobile testing services, we recommend the HEM Data bundle. Please give us a call if you have any questions about the Clean Truck Check program.
