Transportation: Ban on Foreign Laser Sensors

Securing Infrastructure from Adversaries Act of 2025

Law

This bill stops the Department of Transportation from buying or using special laser sensors, called LiDAR, from countries that are considered rivals to the U.S. LiDAR is the technology that helps self-driving cars and smart traffic lights "see" their surroundings by bouncing light off objects to create a map.
Any company that wants a contract or a grant from the government for transportation projects would have to prove they aren't using these foreign-made sensors. This is meant to protect national security by preventing foreign governments from potentially spying on U.S. roads or hacking into traffic systems.
The new rules would officially start on June 30, 2026. There are some exceptions for safety testing and research, which allows experts to keep studying the technology to make sure vehicles stay safe on the road even if they use these specific parts.
The Secretary of Transportation can allow an exception if it is very important for the country, but they must explain why to Congress first. This helps make sure the government can still finish important projects if they can't find enough American-made sensors right away.
