What are the Clean Truck Check requirements?
Similar to Smog Check for light-duty vehicles, Clean Truck Check is a CARB program requiring vehicle testing to ensure that heavy-duty vehicles’ (including motorhomes) emissions control systems are properly functioning when traveling on California’s public roads and highways.
- Vehicles that are non-gasoline, over 14,000 pounds manufacturer's GVWR and operate on California public roads or highways (including motorhomes) subject to Clean Truck Check must be reported in CTC-VIS at https://cleantruckcheck.arb.ca.gov. Non-CA registered motorhomes are not subject to Clean Truck Check.
- Annual compliance fees need to be paid by the vehicle’s compliance deadline, which is shown in CTC-VIS, and must be paid in CTC-VIS.
- Microsoft Edge browser should be used to make payments to ensure that there are no unnecessary delays.
- Payments must be made through your CTC-VIS account and may only be made by debit or credit card, or eCheck. Paper checks will not be accepted.
- Emissions compliance testing requirements are effective October 1, 2024. Testing deadlines begin January 1, 2025, and require submission of a passing Clean Truck Check emissions compliance test. Compliance deadlines for motorhomes are available at Agricultural Vehicles & California Motorhomes Annual Compliance Requirements | California Air Resources Board.
How do I test my motorhome?
California registered motorhomes are required to undergo an annual emissions compliance test. These vehicles may be tested up to 90 days prior to the vehicle’s testing deadline to provide time for any necessary repairs. Emissions compliance tests must be performed by a Clean Truck Check credentialed tester. You may search for credentialed testers by location at Available for Hire Credentialed Testers | California Air Resources Board.
What do I do if I have a CA DMV registration hold labeled Clean Truck Check(SB210)?
California Department of Motor Vehicles (CA DMV) automatically places registration holds on vehicles not compliant with Clean Truck Check. To avoid any potential registration holds, please ensure the vehicle is reported in CTC-VIS, annual compliance fees are paid, and annual emissions compliance testing requirements have been met.
