U.S. Government Lawsuit Against California: The U.S. Department of Justice has filed lawsuits to prevent California from enforcing strict emissions standards for heavy-duty trucks, claiming federal law preempts these regulations following President Trump's actions to void California's waivers under the Clean Air Act.
Impact on Emission Standards and Electric Vehicles: The lawsuits aim to challenge California's authority to set higher pollution limits and promote electric vehicles, arguing that such state-level initiatives disrupt a level regulatory playing field and consumer choice in the trucking industry.
