The bill preserves drivers' choice and some local safety protections at the cost of limiting federal regulatory tools that can reduce vehicle emissions, which may worsen air quality and raise long-term health and compliance costs.
Vehicle owners and drivers (especially middle-class families and taxpayers) keep the choice to avoid mandated start-stop systems, preventing potential repair or retrofit costs.
Local governments and agencies can retain or implement measures that reduce the risk of increased carbon monoxide exposure from engine restart behavior, preserving public safety where needed.
Residents and local communities (including middle-class families and local governments) may experience worse local air quality because the bill limits federal regulatory tools that reduce vehicle idling and tailpipe emissions.
Taxpayers and families could face higher long-term healthcare and environmental remediation costs if reduced adoption of start-stop systems leads to greater pollution exposure and associated illnesses.
Federal agencies' ability to pursue fuel-efficiency or emissions-reduction strategies may be constrained, potentially shifting compliance burdens and costs to states, local governments, or taxpayers.
Based on analysis of 2 sections of legislative text.
Requires EPA and DOT to repeal and stop promoting or requiring automatic engine idle start-stop systems within one year, with a narrow CO-poisoning safety exception.
Official title: To direct the Administrator of the Environmental Protection Agency and the Secretary of Transportation to repeal or rescind certain actions, initiatives, policies, and regulations related to engine idle start-stop technology, and for other purposes.
Introduced November 20, 2025 by Doug Lamalfa · Last progress November 20, 2025
Requires the EPA Administrator and the Secretary of Transportation to rescind any agency action, policy, initiative, or regulation that promotes, incentivizes, or requires automatic engine idle start-stop technology on vehicles, and bars the agencies from issuing similar measures going forward. Agencies must rescind covered actions within one year, may keep measures only if repeal would increase carbon monoxide poisoning risk, and must provide a joint report to Congress at 180 days and a final report within one year describing compliance.
