Final answer:
You are not allowed to use your horn when it does not contribute to driving safety, such as out of frustration at other drivers, to alert non-road users, or when it could cause undue disturbance.
Step-by-step explanation:
You are not allowed to use your horn while driving when it serves no clear safety purpose. The horn should be used only to ensure safe operation or to warn other road users of your vehicle's presence for safety reasons. Using your horn unnecessarily, such as honking at a pedestrian like a woman pushing a stroller without a safety reason, or expressing frustration like when driving behind a slower car (illustrated by the story of Peter behind a gray-haired elderly man), is generally considered improper use of the horn. Additionally, many local ordinances and state laws prohibit the use of a vehicle's horn in a non-emergency situation or using it to an extent that it creates noise pollution or disturbs the peace. To summarize, a horn should not be used:
- Out of impatience or anger (e.g., in traffic jams, at slow drivers)
- To alert individuals not on the road (e.g., pedestrians on the sidewalk)
- When it may cause undue disturbance (e.g., residential areas at nighttime)
- In a situation where it will not contribute to driving safety
