Ever had that moment where a driver doesn’t seem… right, and you’re thinking: Okay, what do I do next, and what does DOT actually require? In this video, Kathy Close from J. J. Keller & Associates walks through reasonable suspicion training for supervisors in plain English, including what applies to CDL fleets under DOT drug and alcohol testing rules. 


You’ll learn: 

  • Who this training applies to (and who it doesn’t) 

  • Who can be designated to make a reasonable suspicion decision 

  • What DOT requires for supervisor training time and topics 

  • Training format options (online, class, video kit) and what to keep for audit proof 

  • The alcohol testing clock: what “2 hours” and “8 hours” really means 

  • How to approach a driver with privacy, discretion, and respect 

  • Why escorting a driver can be a smart risk-management move 

  • How to recognize when a medical issue may look like impairment 


If you’re in safety, compliance, HR, ops, maintenance leadership, or you’re the “backup supervisor” on nights and weekends, this one’s for you.  If this helped, hit like and subscribe for more fleet compliance and safety explainers.
