We encourage you to review these documents beforehand to ensure the most collaborative and informative experience. The Advanced Clean Fleets Regulation Overview fact sheet will give you some basic information on the different components of the ACF regulation. Please note that your vehicle or fleet may be affected by several other CARB regulation that are currently in place. Visit our CARB TruckStop page to learn more about new California requirements for heavy-duty vehicles.


To meet California's health-based air quality standards and greenhouse gas emission reduction goals, the trucks and buses operated in the state and the fuel they use must be transformed away from petroleum. California is working to meet the Governor’s goal of one hundred percent zero-emission transportation where feasible by 2045.

The ACF regulation apply to fleets performing drayage operations, those owned by state, local, and federal government agencies. The regulation affects medium- and heavy-duty on-road vehicles with a gross vehicle weight rating greater than 8,500 pounds, off-road yard tractors, and light-duty mail and package delivery vehicles.
