According to the General Traffic Regulations, what characteristics must the sound emitted by acoustic signals, such as the horn, possess?

Question

DentroTest · Accepted Answer

The correct answer is a non-strident sound. According to regulations, acoustic signals must emit a continuous, uniform sound of sufficient intensity to be heard, but they must not be strident (meaning shrill, harsh, or musical notes). The goal is to warn of the vehicle's presence or a danger without unduly startling other road users or contributing unnecessarily to noise pollution. 'Very high-pitched sound' is incorrect because, while it can be high-pitched, the governing rule is the lack of stridency. 'Any sound' is incorrect because the sound must be homologated.
