This guideline describes the permitted uses of multi-message (3-panel) signs for Traffic Management for Works on Roads.
In the near future Main Roads will review its Code of Practice for Events on Roads to include the use multi message signs. In addition a Code of Practice for Emergencies is currently being developed and this could also see the use of multi message signs.
Multi-message signs are an alternative to stand-alone signs. They are usually more conspicuous than stand alone signs because of the striking colour combination, and they make the task of signings easier and cheaper due to the lightweight material used in the signs construction. Multi-message signs may be used in conjunction with stand alone signs as required.
Guidelines for Use
The use of multi-message signs shall comply with the following requirements.
Frames for Multi-Message Signs
Substrates for Multi-Message Signs
A variety of different materials can be used for the sign substrates including the following:-
The substrates for the signs shall be of sufficient thickness and rigidity to prevent the signs being blown out of the frame.
The rear of the sign substrate shall be non-reflective.
Labelling Ownership of Message plates
The rear of the signs may be marked to identify the owner of the sign, subject to the following conditions.
