PACCAR and Other Truck Manufacturers Sue California Over Zero-Emission Vehicle Plan

PCAR
September 20, 2025
PACCAR, along with other major truck manufacturers, has filed a lawsuit against the California Air Resources Board (CARB) over its zero-emission vehicle (ZEV) plan. The lawsuit seeks clarity regarding a conflict between state and federal emissions regulations, which the truckmakers argue places them in an 'impossible position.' The manufacturers contend that they have been caught in the crossfire following a decision to revoke waivers granted during a previous U.S. presidential administration. This legal challenge highlights the complexities and uncertainties facing the heavy-duty truck industry as it navigates evolving environmental mandates. The lawsuit aims to resolve the regulatory inconsistencies that affect the design, production, and sale of commercial trucks. The outcome could significantly influence the pace and cost of the transition to zero-emission vehicles for PACCAR and its competitors.
