What is ECE 104??
UN/ECE/REGULATION No 104 provides guidelines for retro-reflective line or contour safety markings of heavy goods vehicles and their trailers.
Contour marking means applying a continuous rectangular strip or series of strips which identify the entire length, width and height of the vehicle.
Line marking means applying a continuous strip or series of strips which identify the entire length and width of the vehicle, allowing other motorists extra time to react when approaching a HGV at night or in poor visibility conditions.
Vehicles with retro-reflective contour markings are less likely to be involved in an accident by 21% at night.
