How should a vehicle's horn sound?

• A. A continuous beep for at least 10 seconds
• B. A single sound heard at a distance of at least 100 meters
• C. A rapid series of beeps
• D. A low volume buzz

Answer: (B)

The sound of a vehicle's horn is designed to be an effective warning or alerting device for other road users. The correct answer emphasizes that a vehicle’s horn should produce a single sound that can be heard at a distance of at least 100 meters. This requirement ensures that the horn is loud and clear enough to capture the attention of pedestrians, cyclists, and other vehicles, thereby enhancing safety on the road. A single, identifiable sound is crucial because it prevents confusion over the message being conveyed. If the horn were to sound continuously or be a rapid series of beeps, it might lead to misunderstandings among those who hear it, possibly resulting in dangerous situations. Additionally, a low-volume buzz would not adequately serve its purpose, as it wouldn't ensure that other road users are alerted in time.
