California’s Advanced Clean Trucks (ACT) regulation, aimed at promoting zero-emission vehicles, mandates manufacturers of medium and heavy-duty vehicles to sell an increasing percentage of zero-emission vehicles each year. While the regulation does not ban motorhome sales, it will impact the availability of motorhomes in the state, as well as in additional states that follow CARB regulation.
UPDATE 2/10/25: RV Industry Association, State Trucking Associations Address Advanced Clean Truck Rule Implementation
The latest: The California Air Resources Board’s Advanced Clean Truck rule has been adopted by ten other states across the country. Rules in Massachusetts, New Jersey, New York, Oregon, and Washington will take effect with the 2025 model year. Meanwhile, rules in Vermont will take effect with the 2026 model year, and those in Colorado, Maryland, New Mexico, and Rhode Island will begin the 2027 model year.
So far, legislation has been introduced in three of the five 2025 states – Massachusetts, New Jersey, and Oregon – to delay the implementation of the Advanced Clean Truck rule until at least January 1, 2027. The bill in New Jersey had a hearing in early December before the Assembly Transportation Committee, which unanimously reported out the bill to the full Assembly. State legislators in New York, particularly in the State Senate, are also looking to introduce similar legislation.
The next steps: RV Industry Association staff have contacted the state trucking associations in Massachusetts, New Jersey, New York, Oregon and Washington— the five states with a 2025 model year. The RV Industry Association is willing to participate in coalitions with these states to advocate for an RV exemption or delay in implementation.
RVIA Statement:
Because there are no certified zero emissions chassis rated for motorhomes, the California Air Resources Board’s (CARB) ACT regulation could impact the availability of motorhomes in California beginning January 1. Motorhomes can still be sold either through utilizing the credit market or generating a carry forward deficit that will have to be offset by the chassis manufacturer credits within three years.
The RV Industry Association is in active discussions with CARB, along with our manufacturers and dealer partners, to identify and implement practical solutions that will ensure consumers and RVers can purchase and enjoy all types of RVs in California. We remain committed to working toward a sustainable path forward that supports both CARB’s goals and the RV and active outdoor lifestyle. We are also exploring all options to ensure all Americans will continue to be able to purchase new motorhomes.
