When are you allowed to whistle or horn in non-designated zones?

• A. Only as required by rule, crossing protection, or when approaching public crossings and in specified zones per NORAC.
• B. Whenever you feel like.
• C. Only at night.
• D. Never at all.

Answer: (A)

Sounding the horn is a safety requirement, not a personal choice. In non-designated zones you may whistle or horn only when the rule calls for it, when crossing protection devices are active, or when approaching public crossings and in any zones NORAC specifically designates for horn use. This keeps warning signals where they’re needed to protect the crossing and people nearby, while reducing unnecessary noise. So you don’t horn just because you feel like it, and you don’t refrain entirely when you’re in zones where NORAC requires it for crossing protection or approaching a crossing.
