If your truck breaks down and is immobilized on the roadway or shoulder of a dual carriageway, what signaling measure must you take?

Question

DentroTest · Accepted Answer

The V-16 is the luminous hazard warning device: a truck immobilized by a breakdown on the roadway or shoulder of a dual carriageway is signaled by activating it and placing it on the highest possible part of the vehicle, so that it can be seen as far away as possible and without going down onto the road to signal on foot. Warning triangles ceased to be valid on 1 January 2026, so switching on the hazard lights and walking along the road to place one behind the vehicle is not a valid option, besides the risk of being run over. Asking another truck to tow the broken-down vehicle is not correct either: on public roads it can only be towed by a roadside assistance vehicle, not by another truck (Royal Decree 159/2021, Article 8(4)).
