What it does
This bill prohibits the U.S. Department of Transportation from procuring, using, or contracting with entities that use foreign-made LiDAR technology (a sensor used in autonomous vehicles and infrastructure monitoring) from designated adversary countries or companies. It also blocks federal loan and grant funds from being used to purchase such technology, with a national-interest waiver available to the Secretary of Transportation. The ban takes effect June 30, 2026, and exempts vehicle safety testing and research.
Why we flagged it
The bill's core function is to exclude foreign-made LiDAR sensors from U.S. federal transportation procurement and grant-funded projects on national-security grounds. It is a targeted supply-chain restriction, not a broad infrastructure bill despite its committee assignment.
What the text implies
- The 15-day waiver notification window may be too short for meaningful congressional review, effectively delegating security decisions to the executive branch with minimal legislative oversight.
- By cross-referencing definitions to the 2025 National Defense Authorization Act (10 U.S.C. note prec. 4651), the bill's scope depends on which countries and companies are designated there—those designations are not visible in this text and may shift without amending this statute.
