Diesel Truck Liberation Act of 2026

This bill would bar any federal law, regulation, or executive order from requiring vehicle and engine makers, importers, or distributors to install, certify, or maintain emissions control devices or onboard diagnostic systems. It would prohibit the Environmental Protection Agency from issuing or enforcing 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. Existing federal regulations on installing, modifying, or removing these devices would have no effect, and past prison sentences for such conduct would be vacated and related records expunged.
