Management of overdimensional and overmass vehicles

Overdimensional and overmass vehicles are the generic titles for groups of vehicles which, because of either their construction, use or type of load, are permitted controlled access of the road system with mass or dimensions exceeding statutory limits. Such vehicles can be divided into two basic groups: 1) low loaders and similar vehicles which carry indivisible items; and 2) plant items, such as cranes, concrete pumps, drilling rigs, agricultural equipment and other items where the special purpose of the vehicle is not for the carriage of goods on the road network. This paper has been produced by officers of the NRTC following recommendations by AUSTROADS, input from the Police, road agencies, the transport industry (including transport associations, owners and operators, pilot vehicle associations, house removers, heavy haulage operators), construction and crane industries, the farming associations and sign manufacturers. It has not yet been endorsed by the Commission. The Commission's role is to consider policy for vehicles with a manufacturer's gross mass rating over 4.5 tonnes. However the policies in this paper could also apply to any permit vehicle regardless of the gross mass rating. Oversize container transport, B-doubles, medium combination vehicles and road trains are not considered in this report, nor are vehicle charging issues.
