<p>The device functions in the following manner: at the moment in which a vehicle loses control, colliding against the guardrail or any road-side protection, a first circuit (generic, electrical for example, but also of another kind) which is part of the device object of the description is interrupted because of the collision, activating in such a way a network of signals, for example luminous, installed at the margins of a sufficiently long stretch of road, so as to alert the other vehicles. At the opportune luminous signalling the vehicles will be warned before time of the sudden accident that has occurred within a few hundred metres and will have the opportunity to decelerate and avoid a collision. At the same time an emergency call will be activated to the forces of order in the area.</p> |
