If a truck with a maximum authorized mass (MAM) of 7,500 kg is immobilized by a breakdown on the shoulder of a dual carriageway, is it required to place the V-16 warning light?

Question

DentroTest · Accepted Answer

When a vehicle is immobilized by a breakdown or accident, the driver must use the regulation hazard warning device to warn of it (General Traffic Regulations, Article 130(4)), which since 1 January 2026 is the connected V-16 warning light. This device is a single light element of the amber color known as amarillo auto, placed on the highest possible part of the immobilized vehicle to ensure maximum visibility, and its light covers 360 degrees (General Vehicle Regulations, Annex XI, V-16). That is why one is enough, on the roof, and no other has to be placed at the rear. Being on the shoulder does not exempt the driver from using it, because the shoulder is part of the traffic area of the road (roadway plus shoulders) and the obligation applies to a vehicle immobilized with no possibility of resuming its journey. The old warning triangles are no longer valid.
