New pictorial length signage is now available for heavy-duty vehicles, designed to enhance road safety by providing a clearer visual of the length of the vehicle in front of them, before attempting to overtake. The signs show the number of trailers and the total length of the vehicle, depicted with an equivalent number of car lengths. They can be displayed on the rear of restricted access vehicles, including road trains and other heavy vehicles, to improve awareness and safety on the road.
The new signage can be used instead of, or in addition to the existing ‘ROAD TRAIN’ or ‘LONG VEHICLE’ signs, which currently cover vehicle combinations ranging from 22 to 60 metres in length.
