Speed limits for lorries on single carriageways are set to increase from 40mph to 50mph in a bid to cut congestion.
The announcement by Transport Minister Claire Perry during a visit to the HGV depot, WH Barley, in Old Wolverton on Thursday.
The government believes the proposal will save the transport industry £11million a year with Mrs Perry stating it will reduce dangerous overtaking and get the country moving.
She said: “It felt very appropriate to come to Milton Keynes for the announcement because it is the heart of haulage Britain.
“The speed increase makes tons of sense because the industry called for it and said that if you can speed us up it will get us moving, save us money and reduce congestion, which seemed like a very sensible thing to do.
“There’s nothing more frustrating than a driver with a tailback of cars and there have been some tragic cases of people pulling out while taking an opportunity to overtake.
“It was the first road decision that came across my desk which seemed to be real common sense.”
A six-week consultation on plans to increase the speed limit for HGVs on dual carriageways from 50mph to 60mph will also be launched on August 18.
If given the go-ahead, the change would come into force in early 2015 at the same time as the revised single carriageway limit.
Mark Lancaster MP for MK north, who joined Mrs Perry at the depot, said: “It’s the right thing to do, it stops my constituents getting frustrated and it’s good for the industry because it’s going to save money.”
