The CARB Clean Truck Program is a state initiative aimed at reducing harmful emissions from heavy-duty vehicles to improve air quality and public health.

Starting January 1, 2025, all eligible trucks must meet new compliance standards, including emissions testing and registration in CARB’s database.

This includes RVs that fall under the program’s requirements. This program is essential for businesses operating commercial vehicles in California to avoid penalties and ensure seamless operations.
