DOT-Compliant Drug and Alcohol Testing

Department of Transportation (“DOT”) regualations for drug and alcohol testing


If your company or organization works in some capacity with the agencies listed below, then you are regulated by the Department of Transportation (“DOT”) for purposes of drug and alcohol testing.

  • Agencies covered by DOT for drug and alcohol testing

  • Federal Motor Carrier Safety Administration (FMCSA)
  • Federal Railroad Administration (FRA)
  • Federal Transit Administration (FTA)
  • United States Coast Guard (USCG)
  • Pipeline and Hazardous Materials Safety Administration (PHMSA)

The DOT regulations cover these areas:

  • Who must be tested
  • Under what circumstances must people undergo testing
  • The many roles that are involved in DOT testing (collectors, medical review officers, substance abuse professionals, and others)
  • Record-keeping requirements
  • Employer actions when employees violate the rules
  • Training of employees and supervisors

If you’re regulated by the DOT, then you probably know how very detailed those regulations are.
