What you need to know about DOT Drug & Alcohol Testing

What is a DOT drug test?

A DOT Drug test is a drug test that is regulated by the Department of Transportation (DOT).

In 1991, the U.S. Congress passed the Omnibus Transportation Employee Testing Act when they recognized the need for a drug and alcohol-free transportation industry. This act requires that DOT regulated employers implement a drug and alcohol testing program for their safety-sensitive employees.

The DOT regulations and procedures are listed as 49 CFR Part 40. These rules are published by the Office of Drug & Alcohol Policy & Compliance (ODAPC). The Office of Drug & Alcohol Policy & Compliance publishes and provides authoritative interpretations of these rules. Each DOT agency and the U.S. Coast Guard write industry-specific regulations, spelling out who is subject to testing, when, and in what situation.

Who is required to get DOT drug & alcohol tests?
