The agencies that are regulated under the DOT laws include Federal Motor Carrier Safety Administration (FMCSA), Federal Aviation Administration (FAA), Federal Railroad Administration (FRA), Federal Transit Administration (FRA), Pipeline & Hazardous Materials Safety Administration (PHMSA), and the United States Coast Guard (USCF).
