Diesel Truck Liberation Act of 2025

This bill would bar any federal law, regulation, or executive order from requiring makers, importers, or distributors of motor vehicles or engines to install, certify, or maintain emissions control devices or onboard diagnostic systems. The Environmental Protection Agency could not issue or enforce such requirements under the Clean Air Act or other federal law. No person could face federal civil or criminal liability for making, selling, importing, buying, using, or modifying a vehicle or engine without these devices, and existing federal regulations on installing, modifying, or removing them would have no effect. Prison sentences already given for this conduct would be vacated, and related records would be expunged.
