The bill removes federal emissions requirements and clears prior penalties—giving vehicle owners and industry greater freedom and lower compliance costs—but at the likely expense of higher pollution, shifted costs to states and taxpayers, increased regulatory uncertainty, and weaker enforcement against tampering.
Vehicle owners and buyers (including hobbyists and aftermarket shops) can legally purchase, modify, and operate vehicles without federal penalty for lacking emissions controls or onboard diagnostic systems.
Manufacturers, importers, and distributors are relieved of federal installation, certification, and maintenance requirements for emissions controls, reducing compliance costs for those businesses.
Individuals previously convicted or penalized under federal emissions-device rules will have imprisonment penalties vacated and related criminal/civil records expunged, improving employment and licensing prospects for those people.
People — especially in urban areas — are likely to face higher exposure to vehicle air pollutants because removing federal emissions requirements can increase pollution and harm public health.
The change undermines national Clean Air Act objectives and risks increasing greenhouse gas and pollutant emissions, weakening coordinated federal efforts to reduce air pollution.
States and localities may face higher healthcare costs and regulatory burdens as federal protections are removed, effectively shifting expenses onto taxpayers and local governments.
Based on analysis of 2 sections of legislative text.
Prohibits federal requirements and enforcement of emission control devices and onboard diagnostics on vehicles/engines, voids related federal rules, removes liability, and orders vacatur/expungement for past offenses.
Official title: 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.

Prohibits the federal government — including the EPA — from requiring or enforcing emission control devices or onboard diagnostic systems on motor vehicles and engines, overriding existing federal clean air law authorities. It also removes federal civil and criminal liability tied to those requirements, nullifies existing federal rules that require such devices, and directs vacatur of imprisonment penalties and expungement of records for past offenses related to those requirements.
