The California Air Resources Board (CARB) launched the Clean Truck Check program as a key initiative to improve air quality by cutting emissions from heavy-duty vehicles operating in the state. Also called the Heavy-Duty Inspection and Maintenance (HD I/M) Program, this initiative ensures that trucks and buses actively maintain their emissions systems throughout the lifespan of the vehicle. This initiative plays a vital role in California’s broader goal of reducing smog-forming pollutants and greenhouse gas emissions.
Inspectors periodically perform Clean Truck Check inspections, report emissions, and verify compliance to ensure that high-emitting vehicles are promptly identified and repaired. The program targets both in-state and out-of-state trucks traveling on California roads, highlighting the state’s commitment to cleaner transportation and environmental responsibility.
Understanding the clean truck check requirements is essential for fleet managers, truck owners, and drivers operating in California. Starting in 2023, all heavy-duty trucks with a gross vehicle weight rating (GVWR) over 14,000 pounds must comply with CARB’s Clean Truck Check protocols. Here are the key requirements:
These clean truck check requirements are not optional—they are legally enforceable, and failure to comply can lead to significant fines and registration holds.
The CARB rules for trucks extend beyond just emissions testing. They encompass a wide range of regulations aimed at reducing the environmental impact of heavy-duty vehicles. Key CARB rules include:
For fleet operators and independent drivers, staying compliant with CARB rules for trucks means understanding how these regulations impact both current operations and future planning.
