There are several agencies which are regulated by the Department of Transportation. Federal Motor Carrier Safety Administration (FMCSA) Regulation 49CFR Part 382, Pipeline & Hazardous Materials Safety Administration (PHMSA) Regulation 49CFR Part 199, Federal Aviation Administration (FAA) Regulation 14 CFR Part 120, and Federal Railroad Administration (FRA) Regulation 49CFR Part 219.
The United States Congress recognized the need for a drug and alcohol free transportation industry, and in 1991 passed the Omnibus Transportation Employee Testing Act, requiring DOT agencies to implement drug and alcohol testing of safety-sensitive transportation employees. 49 CFR Part 40 (Part 40) is a DOT-wide regulation that states how to conduct testing and how to return employees to safety-sensitive duties after they violate a DOT drug and alcohol regulation. Part 40 applies to all DOT-required testing, regardless of mode of transportation.
