The Justice Department this week filed two complaints in federal courts against the California Air Resources Board (CARB) regarding the State’s enforcement of preempted emissions standards through its so-called “Clean Truck Partnership” with heavy-duty truck and engine manufacturers. A parallel filing in the court of appeals addresses CARB’s rules for light-duty vehicles, which are also preempted. These actions advance President Donald J. Trump’s commitment to end the electric vehicle (EV) mandate, level the regulatory playing field, and promote consumer choice in motor vehicles.
