When you use the vehicle’s horn for signaling:
- The signal shall be given at a fast and unchanging pace.
- You are lawfully required to honk at least three times.
- Correct answer: The signal should not be longer than needed.
- The signal shall be given in a long and continuous manner.
Why this is the answer
The correct answer in the official bank: The signal should not be longer than needed.
The horn is meant to warn other road users and prevent danger, not to express anger or impatience. The signal should therefore be as short as possible, and not longer than needed to achieve its purpose. A long, continuous honk is not required, and the law does not require a set number of honks or set a special pace.
