Nearly 14 million UK motorists have pledged to drive more economically as a direct result of high fuel costs, according to new research from Green Flag breakdown service.

More than a third (39%) of all motorists will avoid behaviours like heavy acceleration and sudden breaking to help minimise their fuel consumption.

The research reveals that motorists are making significant changes to their driving behaviours, with 41% (14 million) cutting back on the number of journeys they make, and 11% (3.8 million) making better use of public transport.

Eight per cent (2.6 million) of motorists say they have even traded in their old car for something more economical.

Miranda Schunke, spokeswoman for Green Flag, said: "There’s no doubt that the current price, and predicted increase of the cost of fuel is forcing many people to rethink their driving behaviours. Taking the pedal off the metal will not only save motorists money, but will also make roads safer as drivers avoid racing away from junctions. Millions have vowed to be more economical and the knock-on effect of this is safer roads and reduced emissions so there is a silver lining."
