This bill aims to restrict the use of certain foreign-made light detection and ranging (LiDAR) technology within transportation infrastructure projects, effective June 30, 2026. It specifically prohibits the Secretary of Transportation from directly procuring or obtaining covered LiDAR technology , or any LiDAR produced by designated foreign companies or countries. The legislation further prevents the Secretary from entering into, extending, or renewing contracts with entities unless they certify that they will not use such restricted LiDAR technology in the performance of the contract. Additionally, it mandates that federal loan or grant funds provided by the Secretary cannot be obligated or expended to procure, obtain, or use these prohibited LiDAR systems. While imposing these restrictions, the bill does allow the Secretary to issue a national interest waiver on a case-by-case basis, requiring a 15-day notification to relevant Congressional committees. However, these prohibitions are not absolute, as they include specific exemptions for applications related to federal motor vehicle safety standards or motor carrier safety regulations, and do not apply to any grants, operations, procurements, or contracting actions that are for the purpose of vehicle safety testing, research, evaluation, analysis, or training , ensuring that critical safety advancements are not hindered.
