Diesel Truck Liberation Act of 2025

This bill prohibits all federal enforcement of emissions control requirements for diesel trucks. It directly affects diesel truck manufacturers, importers, distributors, and owners by eliminating all federal mandates (including under the Clean Air Act) for emissions control devices or onboard diagnostic systems on diesel vehicles. Key provisions repeal existing EPA regulations, prevent future rulemaking on emissions devices, and expunge past legal records related to non-compliance with emissions standards. The law would remove all federal legal barriers to modifying or removing emissions equipment from diesel engines.
