Question

DentroTest · Accepted Answer

Traffic regulations state that special vehicles (such as tractors or construction machinery) and vehicles under special transport regimes must use the V-2 luminous signal (auto yellow rotating or flashing light) to indicate their position. Its use is mandatory both day and night whenever they are traveling at a speed not exceeding 40 km/h, or when they are working on the road, stopped, or parked. The purpose is to warn other drivers of their presence and slow speed to prevent rear-end collisions. If the V-2 light breaks down, low beam headlights must be used together with hazard warning lights as a substitute measure.
