The U.S. Department of Transportation, specifically the Federal Motor Carrier Safety Administration (FMCSA), is seeking to award a Sole Source contract to the National Law Enforcement Telecommunication System (NLETS), Inc. for the provision of a message-switching network that consolidates access to critical security-related data. This contract aims to enhance FMCSA's ability to conduct safety and security enforcement activities by providing real-time access to vital information such as driver licenses, driver history, and criminal history, which are essential for distinguishing between safety violations and potential national security threats. The contract will be firm fixed-price and is being issued in accordance with FAR 6.302-1, indicating that NLETS is the only responsible source capable of fulfilling the agency's requirements. Interested organizations may submit capability statements or proposals to the primary contact, Elizabeth Johnson, at Elizabeth.Johnson@dot.gov, or the secondary contact, Nickole Jackson, at Nickole.Jackson@dot.gov, with oral communications not being accepted.
