When is it appropriate to use the bus horn?

• A. To greet students as they board.
• B. To warn pedestrians or other drivers when necessary; avoid unnecessary use.
• C. To signal the start of the route.
• D. To alert the dispatcher.

Answer: (B)

Using the bus horn is a safety tool. It’s meant to warn people of potential danger, not to greet students, signal the start of the route, or contact the dispatcher. The best practice is to give a brief, targeted honk only when someone or something might be in the bus’s path and a warning could prevent a collision. Excessive or unnecessary horn use can startle pedestrians or other drivers, distract others, and may even be illegal in some places. For greetings or routine signaling, rely on standard procedures or verbal communication rather than the horn. So, the appropriate use is to warn pedestrians or other drivers when necessary, and avoid using it unnecessarily.
