Ban on Foreign-Made Laser Sensors for Transportation Projects

Securing Infrastructure from Adversaries Act of 2026

Law

This bill stops the Department of Transportation from buying or using a specific type of laser sensor technology called LiDAR from countries considered foreign adversaries. LiDAR acts like a set of 'eyes' for self-driving cars and smart traffic systems, using lasers to map out surroundings in real-time.
Starting June 30, 2026, any company that wants to sign or renew a contract with the Department of Transportation must prove they are not using these foreign-made sensors. This rule also applies to any project funded by federal loans or grants, ensuring taxpayer money is not spent on technology from rival nations.
The goal of this policy is to protect national security. Lawmakers are concerned that sensors made by adversaries could be used to spy on American infrastructure or collect sensitive data about how people and goods move across the country.
There are a few exceptions to the rule. The ban does not apply to scientists doing safety research or testing. Additionally, the Secretary of Transportation can allow the use of these sensors in special cases if they can prove it is in the best interest of the United States.
