What is the DOT "Reasonable Suspicion" Testing Overview for Managers and Supervisors Course?
The DOT “Reasonable Suspicion” Testing Overview for Managers and Supervisors course is an online training program designed for managers and supervisors who oversee commercial motor vehicle drivers and other motor carrier employees in safety-sensitive positions. The course discusses the concept of reasonable suspicion testing, how managers and supervisors can administer the regulation fairly and effectively, and the oral fluids testing method.
Under federal law, managers who suspect that a commercial driver has a substance use disorder or is actually impaired are required to send the employee for immediate drug and alcohol testing. Called reasonable suspicion testing, it is one of the six situations in which motor carrier employees who perform safety-sensitive duties, such as driving, are required to undergo drug and alcohol testing. Areas covered in the course include an overview of reasonable suspicion testing, what makes suspicion reasonable, recognizing signs of substance use disorders, and approaching employees who may be impaired.
The course is 100% online, fully self-paced, approximately 45–60 minutes in length, and accessible on desktop, tablet, and mobile devices.
This course is provided in partnership with MARCOM, a top-rated safety and compliance training content provider.
