Almost half of Scots motorists are slowing down to save money on fuel, according to new research.
The study, by the Energy Saving Trust Scotland, shows that 45 per cent of drivers have eased off the accelerator in order to save money.
About two-thirds of these drivers have cut their average motorway speed by 10mph or more.
This could be costing the country’s economy millions of pounds a year, Department for Transport researchers say.
The YouGov survey, of more than 1000 adults, found that drivers in Lothian are most likely to have slowed, with 52 per cent saying they have reduced speed to save money.
Glaswegian drivers are the least likely to have slowed down, with 62 per cent saying that they drive on the motorway at the same, or an even higher, speed.
The Energy Saving Trust, said: “It comes as no surprise to hear that drivers 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.”
