Reasonable-Suspicion Supervisor Training: What to Document

For motor carriers: A signed blank certificate does not train a supervisor. This resource explains what FMCSA’s reasonable-suspicion supervisor-training rule covers and what a useful completion record should show.

Who needs the training?

Under 49 CFR § 382.603, employers must ensure that people designated to supervise drivers covered by Part 382 receive at least 60 minutes on alcohol misuse and another 60 minutes on controlled-substances use. The purpose is to recognize when reasonable suspicion may warrant testing. The training covers physical, behavioral, speech, and performance indicators. The rule does not require recurrent supervisor training, although an employer may choose refreshers.

What should the record prove?

Keep evidence that the designated supervisor actually completed the training: who was trained, when, who provided it, the alcohol and controlled-substances topics, and the time spent on each. Those are practical evidence details, not a claim that FMCSA mandates one certificate layout. A form signed before training, or one that says only “all supervisors of drivers,” can hide the key question: whether the right person received the required training. See FMCSA’s employer-and-supervisor training guidance.

About the older LBC form

We have not republished the older certificate as a current ready-to-sign document. Use a completion record that matches the training actually delivered and your carrier’s approved process. For related driver-compliance administration, see LBC Fleet’s compliance and driver-support directory. That directory does not, by itself, certify supervisor training.
