The Truck and Bus regulation did not require a waiver and therefore is not at issue in the action of the Trump Administration. The waiver revocation action, in the unlikely event it is finally upheld in litigation, only addresses greenhouse gas and zero emission rules for cars and light-duty trucks. We are fighting this revocation in court.
All CARB regulations on trucks and off-road vehicles, including the Truck and Bus Regulation, continue to be California law. There have been no direct federal law changes to any other rule.
