Q1. Supervisor Training:  Do I need to train my CDL driver supervisors to recognize physical, behavioral, speech, and performance indicators of drug use or alcohol misuse?

A1. Yes. Unless you are an owner-operator employing yourself as the only driver [382.603, Question 3], you must ensure that all supervisors that are designated to supervise CDL drivers undergo a one-time 2-hour training requirement.  The training, at minimum, must include at least 60 minutes of alcohol misuse training and 60 minutes of controlled substance use training, which enables supervisors to recognize signs of drug and alcohol use that support 382.307  reasonable suspicion testing.
