The DfT has announced that some lorries could be allowed to use longer trailers after independent research showed that this could cut carbon without compromising safety.
The research has been published by the DfT alongside a consultation seeking views on proposed changes to allow a two metre increase in the total length of articulated lorries operating within the existing weight limit of 44 tonnes. This would take the maximum permitted length of an articulated lorry to 18.75 metres but would not allow any increase in overall weight.
The DfT estimates that this move could increase capacity for hauliers transporting lightweight goods by up to 13% and cut carbon emissions by around 100,000 tonnes each year.
Mike Penning, road safety minister, said: "These proposals would allow haulage firms to use one larger truck where previously they may have needed to send two vehicles. This will help to make our haulage industry cleaner and greener as well as allowing businesses greater flexibility without compromising safety."
