You should use your horn when:

  1. You see a police officer

  2. You are angry

  3. You want to warn another driver of your presence

  4. You are stuck in traffic

The correct answer is: You want to warn another driver of your presence

Using your horn incorrectly can result in a fine or even worse, an accident. Honking when you are angry or in frustration is not only disrespectful, but can also startle other drivers and potentially cause a collision. It is important to only use your horn to warn another driver of your presence, such as when passing or in a dangerous situation. Honking at a police officer is unnecessary and can be seen as a sign of aggression. Using your horn when stuck in traffic is also unnecessary and can contribute to noise pollution. Therefore, the only appropriate use of your horn while driving is to warn another driver of your presence.
