Is it permitted to use acoustic signals (horn) to warn the vehicle in front of you that the traffic light has turned green?

Question

DentroTest · Accepted Answer

The answer is no, never. General Traffic Regulations are very strict regarding acoustic warnings to prevent noise pollution. The horn may only be used in three exceptional situations: To avoid a possible accident (on any type of road). To warn, exclusively outside built-up areas, of the intention to overtake. To warn that an urgent service is being performed (transporting sick or injured people in a private vehicle). Therefore, using the horn due to impatience or to signal a traffic light change is prohibited both inside and outside urban areas.
