A proposal to trial 60-ton super-lorries on British roads is to be considered by the Government.
An application for the 'road trains' has been submitted to the Department of Transport and a report on the scheme is being prepared for Transport Minister Dr Stephen Ladyman.
The department said it knew of further plans for 84-ton trucks, but had yet to receive an application.
The Road Haulage Association (RHA) would like to see the trial approved as it believes the new heavy goods vehicles would make commercial and environmental sense.
A company called Denby Transport has submitted the application for the 60-ton Denby Eco Link lorry which is divided into two trailers and is 83ft long. The RHA said it would operate only on motorways between regional distribution centres.
A RHA spokesman said: "There are 428,000 trucks registered and if we could reduce that number to have one truck for every two - we're all for it."
Stephen Joseph, of Transport 2000, said: "These road trains are fine for the Australian outback but have no place on Britain's country lanes and town centres."
