The mission of the Department of Transportation (DOT) is to serve the United States by ensuring a fast, safe, efficient, accessible and convenient transportation system that meets our vital national interests and enhances the quality of life of the American people, today and into the future. DOT consists of the Office of the Secretary and eleven individual Operating Administrations: the Federal Aviation Administration, the Federal Highway Administration, the Federal Motor Carrier Safety Administration, the Federal Railroad Administration, the Federal Transit Administration, the Maritime Administration, the National Highway Traffic Safety Administration, the Pipeline and Hazardous Materials Safety Administration, the Research and Innovative Technology Administration, the Saint Lawrence Seaway Development Corporation, and the Surface Transportation Board. The Homeland Security Act of 2002 authorized the establishment of the Department of Homeland Security, which, on March 1, 2003, assumed management of the United States Coast Guard and the Transportation Security Administration, formerly DOT Operating Administrations.
