The Trump administration is taking direct aim at California again as part of its aggressive effort to roll back stricter emissions policies in the U.S., amid growing concerns about rising gas prices.

First things first: In the latest move, the Department of Justice sued the California Air Resources Board in Sacramento federal court, arguing that the state’s vehicle emissions standards unlawfully infringe on federal fuel-economy authority, AP News reported.

  • California (the largest car market in the U.S.) has led the nation’s push to curb vehicle pollution, including a proposal announced in February to offer instant EV rebates.

  • The DOJ’s lawsuit, filed Thursday, follows a move by the administration last summer that blocked California’s plan to ban the sale of new gas-powered vehicles by 2035.

What they’re saying: “Oppressive, expensive electric vehicle mandates drive up costs for American consumers and violate federal law,” said Attorney General Pamela Bondi, per a DOJ press statement. “California is using unlawful policies from the last administration to create exorbitant costs for our citizens…”

Why it matters: Regulatory shifts in California can influence product planning, EV strategy, inventory mix, and compliance expectations across the broader market, especially for retailers tied to brands with aggressive electrification targets.

Between the lines: The suit drew an immediate response from Gov. Gavin Newsom’s office, which pointed to the timing of the move given surging gas prices and growing consumer interest in electric vehicles.

  • On Monday, the average gas price in California was $5.52 a gallon, up from $3.71 nationally and $2.94 a month ago.

  • In the week starting March 2, EVs accounted for 22.4% of all vehicle research on Edmunds, up from 20.7% the previous week, amid rising gas prices.

What they’re saying: “Gas prices are soaring nationwide because of Trump’s reckless choices, and now he’s attacking the Golden State for trying to give Californians more freedom and cheaper options,” Newsom spokesperson Anthony Martinez said in a statement, per AP News.

Bottom line: The latest legal fight adds more uncertainty to an already unsettled emissions and EV landscape. For dealers, that means staying flexible on inventory, consumer messaging, and long-term planning as policy battles continue to shape how quickly the market moves toward electrification.
