What Is California’s Clean Truck Check Program?
Clean Truck Check, also known as the Heavy-Duty Inspection and Maintenance (HD I/M) program, is administered by the California Air Resources Board (CARB). It establishes emissions-compliance requirements for covered heavy-duty vehicles operating on California public roads.
The program includes vehicle reporting, applicable compliance fees, and emissions testing according to the requirements and deadlines that apply to each vehicle.
For current official requirements, visit the California Air Resources Board Clean Truck Check program page.
Which Vehicles May Need a Clean Truck Check?
The program generally applies to diesel and alternative-fuel heavy-duty vehicles with a gross vehicle weight rating (GVWR) over 14,000 pounds that operate on California public roads and highways. Depending on the vehicle and applicable rules, covered vehicles may include commercial trucks, buses, certain personal-use vehicles, and vehicles registered outside California.
Not every heavy-duty vehicle is covered. Exemptions and special requirements may apply, so vehicle owners should check the current program rules to determine whether their vehicle must comply.
Check your vehicle’s GVWR, fuel type, registration status, and current program requirements before arranging testing.
What Do Vehicle Owners Need to Do?
Owners of vehicles covered by Clean Truck Check generally need to complete the program’s applicable compliance steps. These may include:
- Report the vehicle: Make sure the vehicle is reported in CARB’s Clean Truck Check Vehicle Inspection System (CTC-VIS), when required.
- Pay applicable fees: Review your account for compliance fees and payment deadlines.
- Complete required emissions testing: Arrange testing using an approved method and a qualified provider.
- Meet your deadlines: Follow the compliance dates applicable to your vehicle and shown in the official system.
- Address emissions problems: If your vehicle does not pass, determine what repairs or further diagnostics are needed before retesting.
Requirements can change and may vary by vehicle. Consult CARB’s current guidance and your CTC-VIS account for instructions specific to your vehicle.

Why Clean Truck Check Compliance Matters
Keeping emissions-control systems in proper working order helps covered vehicles meet California’s emissions requirements. Completing required testing on time can also help vehicle owners manage their compliance obligations.
Clean Truck Check testing may identify emissions-related issues that need further investigation. If a vehicle does not meet the applicable requirements, the cause should be diagnosed and addressed before arranging any required retest.
Do not assume that a vehicle will pass simply because it appears to run normally. Follow the testing and compliance requirements that apply to your vehicle.
