Mullen Announces CARB Approval for 2025 Class 3 EV Cab Chassis Truck
The recent Advanced Clean Fleets regulation requires state and local government fleets, including city, county, special district, and state agency fleets, to ensure 50% of vehicle purchases are zero-emission beginning in 2024 and 100% of vehicle purchases are zero-emission by 2027.

Mullen Automotive has received certification from the California Air Resources Board on the 2025 Mullen THREE, Class 3 all-electric low cab forward chassis truck. The certification is awarded to vehicle manufacturers who meet specific emissions standards in compliance with CARB regulations.
The District of Columbia and 14 states, including California, have adopted vehicle standards under Section 177 of the Clean Air Act (42 U.S.C. §7507), which requires additional approvals beyond EPA regulations.
A copy of Mullen’s 2025 Class 3 CARB certification can be found on MullenUSA.com. The Company previously received 2024 Model Year CARB certification for the Mullen THREE in January 2024.
Impact of CARB's Advanced Clean Fleets Regulation
CARB certification opens the Mullen THREE to critical state EV incentive programs, which vary by each eligible CARB-compliant state. The certification takes on even more significance with CARB’s recent Advanced Clean Fleets (“ACF”) regulation, which will have a requirement that state and local government fleets, including city, county, special district, and state agency fleets, ensure 50% of vehicle purchases are zero-emission beginning in 2024 and 100% of vehicle purchases are zero-emission by 2027. Fleets that fall under high priority may also elect to utilize ZEV milestones as an option to meet overall ZEV targets.
CARB-compliant states and locations include: California, Connecticut, Colorado, Delaware, Maine, Maryland, Massachusetts, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont and the District of Columbia.
Incentive Programs: California's HVIP and Beyond
California’s HVIP project is an example of a state incentive program available to CARB-certified vehicles. Under HVIP, the Mullen THREE EV truck, with a suggested MSRP of $68,500.00, may qualify for a rebate of up to $45,000.00 and, when combined with the available $7,500.00 federal tax credit, the net effective cost of the Mullen THREE would be less than $20,000.00.
“Our vehicles are CARB approved and ready for delivery with many states and local governments offering very strong incentives to electrify commercial fleets,” said David Michery, CEO and chairman of Mullen Automotive.
