The use of alcoholic beverages or intoxicants on duty is:

• A. Prohibited while on duty or reporting for duty
• B. Allowed after lunch
• C. Prohibited only on trains
• D. Allowed if not impaired

Answer: (A)

Alcohol and intoxicants must not be used while you are on duty or reporting for duty. This is to protect safety, since alcohol and drugs impair reaction time, judgment, and coordination—essential for operating trains and equipment. The rule is strict: you’re not allowed to come in or stay on duty under the influence, and you shouldn’t be on duty just because you think you’re not impaired. Options that suggest drinking after lunch, only on trains, or only if not impaired all imply conditions that could still put people at risk, which isn’t acceptable in these safety rules. So the correct stance is that use is prohibited while on duty or reporting for duty.
