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 mapping). Federal loan and grant recipients must certify they won't use covered foreign LiDAR. The Secretary of Transportation can waive the ban on a case-by-case basis if deemed in the national interest, with 15 days' notice to Congress. The ban takes effect June 30, 2026, but exempts vehicle safety testing and research.
Why we flagged it
The bill establishes a targeted prohibition on federal procurement and contracting involving foreign-made LiDAR technology, with national-security framing. It functions as a sectoral trade/supply-chain restriction rather than a broad infrastructure or safety measure.
What the text implies
- The bill references definitions in the 2025 NDAA (10 U.S.C. note prec. 4651) without restating them in this text, creating opacity about which specific countries and companies are actually covered—a reader cannot determine the scope without cross-referencing external legislation.
- The Secretary's waiver authority is broad ('national interest') and requires only 15-day notice to committees, potentially allowing case-by-case exceptions that could undermine the stated prohibition and create regulatory uncertainty for contractors.

Who stands to gain
domestic LiDAR manufacturers and suppliers; autonomous vehicle technology companies with U.S.-based supply chains; defense and infrastructure contractors dependent on approved LiDAR vendors
