Securing Infrastructure from Adversaries Act of 2025

This bill aims to keep certain foreign-made light detection and ranging (LiDAR) technology out of U.S. transportation projects. It tells the U.S. Department of Transportation (DOT) not to buy this LiDAR, not to fund it with grants or loans, and not to sign or renew contracts unless the contractor promises they won’t use it for the job. The terms “covered” countries and companies come from existing federal law, and the rule applies to LiDAR made in, provided by, or coming from those sources .

There is a narrow safety valve: DOT can grant a waiver if it’s in the national interest and Congress is notified 15 days ahead. The rule starts June 30, 2026, and does not apply to certain vehicle safety exemptions or to projects focused on testing, research, evaluation, analysis, or training related to vehicle safety.

Key points

• Who is affected: DOT; companies and other entities that get DOT contracts, grants, or loans.
• What changes: No buying, funding, or contracting that uses covered foreign LiDAR; contractors must certify they won’t use it on the contract. Waivers are possible only with advance notice and a national interest finding .
• When: Applies to funds and contracts on or after June 30, 2026. Certain safety-related exemptions and research/training activities are not covered.
