The California Air Resources Board (CARB) Clean Truck Check program, also known as the Heavy-Duty Inspection and Maintenance (HD I/M) program, is a statewide emissions compliance program for heavy-duty diesel and alternative fuel vehicles operating in California.
Most diesel vehicles with a Gross Vehicle Weight Rating (GVWR) over 14,000 pounds operating in California are required to comply with the Clean Truck Check program, including owner operators, fleets, and many out-of-state vehicles.
Certain vehicles may be exempt including gasoline-powered vehicles, military tactical vehicles, some personal-use motorhomes, historical vehicles, and zero-emission vehicles.
Many vehicles currently test twice per year, with some vehicles expected to move to four times per year beginning in 2027.
If a vehicle fails inspection, repairs must be completed before the vehicle can return to compliance. Failure to maintain compliance may result in DMV registration holds, fines, or enforcement actions.
