On-Road Heavy-Duty Vehicles
On-road heavy-duty vehicles include a wide range of vocational and drayage trucks, as well as buses. Emissions from these vehicles are major contributors to air pollution and effect the health of all Californians. CARB works closely with our partner agencies, vehicle manufactures, and community stakeholders to reduce the health and climate impacts of these vehicles.
