California's tougher truck pollution limits — the state can't enforce them

California's rules set tighter limits on truck exhaust than federal rules do. They only worked because the EPA let the state go further. Congress canceled that, so the state can no longer use them.

California's zero-emission truck program — no longer in effect

The EPA decision did more than one thing. It also backed the state's plan for trucks that give off no exhaust. And it backed its airport shuttle rules and its approval of clean drive systems.

Relief for the trucking industry — California's tougher emission rules canceled

Truck and engine makers had to meet extra California rules on warranty and upkeep for big engines. Those rules are gone. Only the federal rules now apply.

More about this bill

Trucking companies in California no longer have to meet the state's tougher pollution rules for big trucks. Congress voted to cancel the federal decision that let the state enforce those rules. It became law on June 12, 2025. The canceled decision covered more than truck exhaust limits. It also covered warranty and upkeep rules for big engines. And it covered the state's zero-emission truck program and airport shuttle rules. Federal law bars states from writing their own rules for car and truck exhaust. California can ask the EPA to let it go further. The EPA had said yes in April 2023. Most people see no change in daily life.
