Generated guidance. Confirm the source and its applicability before you act. How we check sources.

Short answer

Supervisors must receive at least 60 minutes of training on alcohol misuse and an additional 60 minutes on controlled substances use. The training covers physical, behavioral, speech, and performance indicators of probable misuse. Recurrent training is not required.

The rule says

"The training shall include the physical, behavioral, speech, and performance indicators of probable alcohol misuse and use of controlled substances." (49 CFR 382.603)

"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." (49 CFR 382.603)

In plain English

The training helps supervisors make informed decisions about when to require a driver to undergo testing. In practice, this means supervisors need to be able to recognize specific indicators, such as changes in behavior or speech patterns, that may suggest a driver is under the influence.
