Question 4073
In a built-up area, are vehicles allowed to use audible warnings?

- Yes, to warn the driver of another vehicle of your intention to pass them.
- Yes, unless a sign prohibits it.
Show answer and explanation
Correct answer: Only exceptionally, to avoid a possible accident.
In a built-up area, you may use the horn only in exceptional cases: to prevent a possible accident or to let others know you are responding to an emergency in a vehicle that is not an emergency vehicle. Honking to announce that you are going to pass is allowed only outside built-up areas. Honking without one of these reasons is prohibited even if there is no sign saying so.
