Question

DentroTest · Accepted Answer

Sound warnings (the horn) are very restrictively regulated to avoid noise pollution and to avoid startling other users. The traffic regulations authorize their use only in three specific cases: to avoid a possible accident (both inside and outside built-up areas), to warn of the intention to overtake on roads outside built-up areas, or when carrying out an urgent service in a non-priority vehicle (for example, transporting a seriously ill person). Using the horn to greet acquaintances, to warn of our presence when there is no danger, or to show impatience is completely prohibited.
