Securing Infrastructure from Adversaries Act of 2026

This bill, titled the Securing Infrastructure from Adversaries Act of 2026, restricts the U.S. Department of Transportation from contracting with or providing grants to companies that use or source LiDAR technology from specific foreign countries or entities. It requires companies seeking transportation contracts to certify that they will not use prohibited LiDAR technology, while allowing the Secretary of Transportation to grant waivers on a case-by-case basis if the activity serves the national interest. The restrictions apply to contracts and funding obligations made on or after June 30, 2026, but exclude certain safety-related research, testing, and regulatory exemptions.
