DOT Reasonable Suspicion Supervisor Training – Drugs
Transportation employees of DOT-regulated employers who perform tasks that have been defined as “safety-sensitive” are subject to drug and alcohol testing. This includes “reasonable suspicion” testing, which is required when a properly trained supervisor suspects that an employee is under the influence of alcohol or illegal drugs based on the employee’s appearance, behavior, speech, or smell. Supervisors and company officials who may need to make a “reasonable suspicion” test determination are required to complete at least 1 hour of training on the signs and symptoms of DOT-prohibited drug use. This course describes the five DOT-regulated drug classes, including their signs and symptoms of use, the types of observations that can be used for reasonable suspicion drug test determinations, and what happens during a reasonable suspicion interview, specimen collection, and drug testing.

Sample Video Transcript
DOT drug testing regulations exist for five classes of illegal drugs:
- Marijuana, or Cannabis
- Cocaine
- Amphetamines
- Opiates, or opioids
- Phencyclidine, or PCP
These drugs have different physical and behavioral signs and symptoms, so they are discussed separately in this module. However, supervisors can make reasonable suspicion test determinations based on any sign or symptom of illegal drug use, without specifying the drug or even the drug class. So you don’t need to worry about keeping track of which signs and symptoms are associated with each drug. It is more important to be alert to changes in employee behaviors, actions, and appearances.
