Securing Infrastructure from Adversaries Act of 2026
SB4000, titled the Securing Infrastructure from Adversaries Act of 2026, would bar the Secretary of Transportation from procuring, obtaining, contracting for, or funding the use of certain light detection and ranging (LiDAR) technology tied to covered foreign countries or covered LiDAR companies. The bill also requires contractors seeking Transportation Department contracts to certify that prohibited LiDAR technology will not be used in performing the contract. In addition, any loan or grant agreement administered by the Secretary would have to ensure that federal funds are not used to buy, obtain, or use the restricted LiDAR technology.
The bill applies to obligations, expenditures, and contracts entered into on or after June 30, 2026. It includes a case-by-case waiver authority for the Secretary, but only if the Secretary provides advance written certification to the relevant congressional committees that the waiver is in the national interest. The bill also carves out exceptions for certain motor vehicle safety standard exemption requests, motor carrier safety waiver or exemption requests, and activities involving testing, research, evaluation, analysis, or training related to vehicle safety.
SB4000 would add a new federal procurement and grant restriction within the Department of Transportation, effectively prohibiting the department from using federal funds or entering into covered contracts involving specified foreign-made LiDAR technology. It would affect transportation contractors, grant recipients, and suppliers in the LiDAR market, particularly entities that source from or are affiliated with covered foreign countries or covered LiDAR companies. The bill would also create a compliance and certification requirement for entities doing business with DOT, while preserving limited waiver authority and safety-related exceptions.
The available context shows the bill was introduced with bipartisan support from Senators Budd, Baldwin, Cotton, and Blunt Rochester, which suggests a generally favorable or at least cross-party interest in the measure. No committee transcript or vote record is available, so there is no recorded debate or formal vote sentiment to assess beyond the bill’s introduction and referral. The framing of the bill as an infrastructure-security measure indicates a security-focused rationale rather than a partisan policy fight.
The main point of contention is likely to be the scope of the foreign-technology prohibition, especially whether it could disrupt transportation projects, raise costs, or limit access to LiDAR suppliers. Another likely issue is the breadth of the definitions incorporated from prior law, which could affect how many companies and products are covered. Supporters would emphasize supply-chain security and protection against foreign adversaries, while critics may focus on implementation burdens, procurement delays, and the possibility that the restrictions could reach otherwise useful technology unless a waiver is granted.
