Sound signal (klaxon, sound signaling device) - a component of the sound signaling, which is equipped with a vehicle. An audible signal is given as a warning to other road users, which helps to avoid dangerous situations. They are classified according to the principle of action, tonality and spectral composition.

As the demand for cars increased, the number of accidents on the roads increased significantly. In many cases, accidents can be avoided if you declare your presence on the road in time. This allows you to make a special sound signal - a mandatory component of any transport during movement.
