Key Questions
The following key questions are answered in this module:
Who is subject to DOT drug and alcohol testing regulations?
Transportation employees of DOT-regulated employers who perform, or who might need to perform, tasks that have been defined by the DOT as "safety-sensitive" are subject to drug and alcohol testing.
Why do DOT regulations address the "misuse" of alcohol and the "use" of drugs?
Because alcohol consumption is legal in the U.S., while the use of the five DOT-regulated drugs is not.
For which illegal drugs does the DOT test?
Marijuana, cocaine, amphetamines, opiates (or opioids), and phencyclidine (PCP)
Under what circumstances are DOT drug and alcohol tests administered?
Safety-sensitive transportation employees are subject to testing in several situations: Pre-Employment, Random, Reasonable Suspicion, Post-Accident, Return-to-Duty, and Follow-Up.
Can an employee who has tested positive for illegal drugs return to their job?
If their employer allows it, and if the employee completes the prescribed program, passes a Return-to-Duty test, and undergoes Follow-up testing, they may return to safety-sensitive duties.
