Show answer & explanationAnswer & explanation
Correct answer: B. To alert other drivers or pedestrians of your presence.
The horn is a safety device designed to be used as a warning signal. Its primary purpose is to alert other road users – drivers, pedestrians, or cyclists – to your presence or to a potential hazard to prevent accidents.
Why the other options are wrong
- A. Turn signals are used for signaling turns or lane changes, not the horn.
- C. While the horn is part of the electrical system, its primary function is not diagnostic.
- D. Using the horn to express anger or frustration is considered aggressive driving and is generally inappropriate and unsafe.
