More than half (51 per cent) of motorists in the South of Scotland have eased off the accelerator to save money on fuel, with 62 per cent of these drivers putting the brakes on their average motorway speed by 10mph or more.
Motorists who follow Fuel Efficient Driving tips could save up to two months' worth of petrol or diesel every year, statistics from the organisation show.
The survey also found 49 per cent of Scottish male motorists are driving their car slower in an attempt to save money on fuel, compared to just 41 per cent of Scottish female drivers.
Laura MacAulay, marketing manager at the Energy Saving Trust Scotland, said: "It comes as no surprise to hear that drivers in the South of Scotland are slowing down to reduce the amount of money they spend on fuel - the faster you go, the more fuel you use.
"There are other ways to save too, however. Fuel efficient driving tips like anticipating road conditions and driving smoothly, shifting to a higher gear as soon as possible and switching off air conditioning all have their part to play - and they don't necessarily slow you down.
"Our research has shown South of Scotland drivers who follow a range of ten simple tips can save two months' worth of fuel each and every year - a huge saving in the current economic climate."
