TRB’s National Cooperative Highway Research Program (NCHRP) Research Results Digest 319: Buy America Issues Associated with the State DOT Procurement of Paratransit Vehicles Using FTA Funds examines the Buy America requirements applicable to state departments of transportation (DOTs) and their sub-recipients in purchases of paratransit vehicles and examines opportunities for change. The report is primarily focused on rural and small urban areas; however, Buy America regulations apply equally to all motor vehicles purchased with U.S. Federal Transit Administration grant funds, regardless of the program through which the grant was awarded.
