HR 8079 Re-checks Congress.gov for new actions and updates the bill's status, and fills in any sponsors, committees, or related bills that are missing. It does not re-pull sponsors/cosponsors/committees/related — those rarely change — and it skips all work if nothing has changed upstream, so it's cheap to click.
Diesel Truck Liberation Act of 2026
To prohibit the enforcement of laws relating to the installation, certification, and maintenance of emissions control devices under the Clean Air Act, and for other purposes.
Summary
This bill prohibits the enforcement of federal laws requiring emissions control devices and onboard diagnostic systems on motor vehicles and engines. It would bar the Environmental Protection Agency from promulgating or enforcing requirements under the Clean Air Act or other federal law related to these devices. The bill eliminates civil and criminal liability for anyone involved in manufacturing, selling, importing, purchasing, using, or modifying vehicles without emissions control devices. All existing federal regulations related to emissions control devices on vehicles would be repealed and have no legal effect. Additionally, any criminal penalties of imprisonment for violations of these emissions control requirements would be vacated, and records of such convictions or civil findings would be expunged.
