What is the V-6 signal?
Ever wondered about those yellow rectangular signs on the back of some trucks in Spain? These are V-6 signals, and they serve an important safety purpose by indicating that the vehicle (or combination of vehicles, like a car with a caravan) is longer than 12 metres. Mandatory for such long vehicles, these reflective signs help other drivers assess the vehicle’s size for safer overtaking maneuvers. Located at the rear, either centered or symmetrically placed, these V-6 signs might also be accompanied by the words “Vehiculo longo” (Long Vehicle) as an additional warning.
