A bill to prohibit the Secretary of Transportation from entering into, extending, or renewing a contract with, or awarding a grant to, an entity that uses or procures light detection and ranging technology from certain foreign entities, and for other purposes.

# S 4000 Summary **What the Bill Would Do** This bill would prevent the Department of Transportation from doing business with companies that use or buy light detection and ranging (LIDAR) technology from certain foreign sources. LIDAR is a remote sensing technology that uses laser pulses to create detailed 3D maps of terrain and objects—it's commonly used in autonomous vehicles, surveying, and infrastructure mapping. If passed, the DOT couldn't sign contracts with, extend agreements with, or award grants to any entity that procures this technology from restricted foreign suppliers. **Who It Affects** The bill primarily impacts companies that work on transportation projects funded or contracted by the Department of Transportation, as well as firms developing autonomous vehicles or performing infrastructure mapping services.

It could also indirectly affect transportation projects and development timelines if companies need to find alternative LIDAR sources that comply with the restrictions. **Current Status** The bill was introduced by Senator Ted Budd (R-NC) in the 119th Congress and is currently in committee, meaning it hasn't yet been debated or voted on by the full Senate. No specific details about which foreign entities would be restricted are provided in the bill summary.
