The "Drug and Alcohol Reasonable Suspicion Training: What Supervisors Need to Know" training is a one-time online training, meaning once it's completed it does not need to be done again unless the supervisor that completes it leaves the company. This training is required by the FMCSA to be completed by at least 1 Supervisor within each company that has 1 CDL driver or more (unless the 1 CDL driver is owner/operator).
