Supervisor Reasonable Suspicion Training

DOT-required supervisor training on recognizing signs of drug and alcohol impairment—60 minutes on alcohol indicators and 60 minutes on controlled substances, delivered by certified instructors with completion certificates for compliance documentation.

Federal regulations require supervisors to complete specific training before making reasonable suspicion determinations. Tests ordered by untrained supervisors may be challenged and deemed inadmissible. When an incident occurs and your supervisor's qualifications are scrutinized, incomplete or inadequate documentation creates significant liability exposure.

DSC delivers DOT-compliant Reasonable Suspicion Training that satisfies 49 CFR §382.603 requirements: a minimum of 60 minutes of training on alcohol misuse signs and symptoms, plus 60 minutes on controlled substances indicators. Our certified instructors use real-world scenarios, case studies, and interactive exercises to help supervisors recognize impairment indicators, document observations properly, and make informed testing decisions. Training is available on-site at your facility, virtually for distributed teams, or through scheduled sessions at our training center. Every participant receives a completion certificate maintained in your compliance files, and we recommend refresher training every 2-3 years to keep skills current.
