Course Description
Driving under the influence continues to be one of the major causes of accidents. To help address this problem, federal law requires motor carriers to implement drug and alcohol testing programs for employees with safety-sensitive jobs, such as driving a commercial vehicle on public roads. In this Reasonable Suspicion Testing Overview for Managers and Supervisors course, you’ll learn how to recognize and respond to signs of drug or alcohol use among commercial drivers. The course explains the rules that support reasonable suspicion testing under federal DOT regulations and why it’s vital for workplace and public safety.
You’ll explore what makes a suspicion “reasonable,” how to document your observations, and what actions you must take when an employee shows signs of impairment or substance use. You’ll also learn how to spot changes in behavior, appearance, or speech that may point to a substance use disorder. The course outlines the difference between stimulants and depressants, the physical symptoms to look for, and how to document what you see, hear, or smell clearly and accurately.
You’ll also learn best practices for handling these sensitive situations, including how to approach employees calmly, protect their privacy, and maintain professionalism—even when emotions run high. By the end of this course, you’ll be equipped to enforce safety standards, support compliance, and take action when needed to prevent accidents and protect lives.
