Question 4581
A traffic light changes from red to green. Is it permitted to use the horn to warn another driver that they can now go?
- Yes, when on an urban road.
- No, under no circumstances.
- Yes, when on a road outside a built-up area.
Show answer and explanation
Correct answer: No, under no circumstances.
No. The horn may be used only in exceptional cases, such as to prevent a possible accident, and telling another driver that the light has turned green is not one of them. Whether you are on a city street or on a road outside a built-up area makes no difference: honking without a valid reason is prohibited on any road.
