If the vehicle is immobilized due to a breakdown on the public road, both on the roadway and on the shoulder, it must be signaled with the emergency signal or light, in addition to the danger pre-signaling device, both day and night. If it is at night, we will also turn on the position lights.
The V-16 danger pre-signaling device is an auto-yellow colored, approved luminous device with geolocation, which works with autonomous power supply (battery). It must be placed on the highest part of the immobilized vehicle, ensuring maximum visibility. Currently, the V-16 is the only legal option for signaling an immobilized vehicle or an obstacle on the road, leaving the pre-signaling triangles in disuse.
