Each employer shall ensure that all persons designated to
supervise drivers receive at least 60 minutes of training on alcohol misuse and
receive at least an additional 60 minutes of training on controlled substances
use. The training will be used by the supervisors to determine whether
reasonable suspicion exists to require a driver to undergo testing under
§382.307. The training shall include the physical, behavioral, speech, and
performance indicators of probable alcohol misuse and use of controlled
substances. Recurrent training for supervisory personnel is not
required.
