A SIGNALLING SYSTEM

A signalling system installable on a vehicle (V) comprising at least one imaging device (3) to be positioned so as to acquire one or more images of at least one space in front of the vehicle (V), at least one processing and control logic unit (4) operatively connected to the imaging device (3) and at least one first signalling element (5) operatively connected to the logic unit (4) and to be positioned such that it is visible behind the vehicle (V). In addition, the processing and control logic unit (4) is capable of commanding the activation of the first signalling element (5) when the imaging device (3) acquires one or more images in which at least one person is present and when the presence of a front vehicle, in which said signalling system is installed and its at least one first signalling element (5) is switched on, is detected in said one or more images acquired by said at least one imaging device (3).
