The United States Department of Transportation (DOT) has made safe and secure transport for all its number one priority. To actively prevent drug abuse as well as alcohol abuse by personnel operating or performing safety sensitive duties, the DOT through the Omnibus Transportation Employee Testing Act of 1991 has made drug and alcohol testing of safety-sensitive transportation employees in aviation, trucking, railroads, mass transit, pipelines and other transportation industries a mandatory procedure.

The DOT rule, 49 CFR Part 40, describes all the required procedures for conducting workplace drug and alcohol testing for the federally regulated transportation industry. The 49 CFR Part 40 provides information on how drug and alcohol testing is conducted, who is authorized to participate in the drug and alcohol testing program, and what employees must do before they may return-to-duty following a drug and/or alcohol violation.
