End DWI Act of 2025
Referred to the Subcommittee on Highways and Transit.
The bill creates a federal minimum standard requiring States to restrict DWI offenders to driving only vehicles equipped with ignition interlock devices for at least 180 days. It conditions certain Federal highway apportionments (3% in FY2027, 5% thereafter) on State adoption and enforcement of that standard, allows State-defined exceptions and violation definitions, and sets rules for withholding, apportioning, availability, and lapse of withheld funds.
Federal conditioning of highway funds versus State sovereignty concerns
Relative to its intended legislative type, this bill establishes a substantive federal policy change by conditioning federal highway funds on State adoption and enforcement of ignition-interlock requirements for DWI offenders, and it embeds that policy within Title 23 with related conforming edits.

Technocratic safety bill with bipartisan appeal, but federalism concerns and funding leverage create friction and legal risk.

Federal conditioning of highway funds versus State sovereignty concerns
Who stands to gain, and who may push back.
These are examples from the analysis, not a ranked list of the most-affected groups.
- Federal agenciesStates failing to comply face 3%-5% federal highway funding withholding, impacting infrastructure projects.
- StatesCompliance requires administrative systems and enforcement costs for states, increasing regulatory burdens.
- Potential burdenLow-income offenders may face financial barriers paying interlock installation and monitoring fees.
Why the argument around this bill splits.
Federal conditioning of highway funds versus State sovereignty concerns
Generally supportive because the bill uses federal leverage to reduce alcohol-impaired driving and save lives.
Sees ignition interlocks as evidence-based and a reasonable national baseline while noting equity and implementation details need care.
Cautiously favorable: supports using evidence-based tools to reduce DWI but wary about federal penalties and administrative burdens on States and individuals.
Would favor implementation support and phased enforcement.
Skeptical or opposed: supports reducing impaired driving but objects to conditioning federal highway funds and expanding federal influence over State criminal justice policy.
Prefers state-led or incentive-based approaches.
