Triple-trailer trucks up to 35 metres in length could soon be on NSW roads following an application to the state government by the Australian Trucking Association.
A number of routes for the ''modular B-triples'' are under consideration, including all roads currently approved for use by road trains as well as between Narrandera and Sydney on the Sturt and Hume highways, the Hume Highway from the Stuart Highway intersection to Albury on the Victorian border and the length of the Newell Highway within NSW.
The modular B-triple route into Sydney would terminate in the industrial areas adjacent to the M7.
The triple-trailer trucks would not be allowed on arterial roads within Sydney or on any suburban streets.
ATA national policy manager David Coonan said increasing the number of trailers on the trucks would mean fewer trucks on the road.
''This application is about moving NSW into better, safer vehicles for the future, so we can manage the safety issues associated with ever increasing freight movement,'' he said.
''If this application is approved, it would be available to all operators and allow the widespread adoption of these higher efficiency vehicles across NSW. By allowing modular B-triple combinations to complete a freight task, we could decrease the number of trucks on our roads, reduce carbon-dioxide emissions, and lessen the wear on our infrastructure.''
