Reasonable suspicion training should be aimed at all supervisors, managers, and human resource personnel. In today’s environment, if you hire anybody, knowing what to look for in terms of a substance abuser is critical for the safety of your company and employees. While DOT regulations specifically require “all persons designated to supervise drivers” to receive 60 minutes of mandatory training on alcohol misuse and 60 minutes on controlled substances abuse (49CFR §382.603), this DOT-required training will also be useful by reviewing a policy for other positions within your company not covered by FMCSA regulations and will give employers and supervisors the information they need to determine if an applicant is a substance abuser before hiring.
