Two out of three motorists are planning to change driving habits because of sky-high fuel and insurance prices.

That is according to a survey conducted by moneysupermarket.com.

Nearly half (48.2 per cent) say their next car will be a more fuel-efficient model, while 11.4 per cent plan to buy a new car that is cheaper to insure and eight per cent plan to ditch their motor and use public transport instead.

Nearly 12 per cent said there were other factors that would influence their choice of vehicle while 8.4 per cent said rising motoring costs would not affect them as they would look to make cutbacks elsewhere.

Moneysupermarket.com's Pete Harrison said car insurance prices had increased by 31 per cent in 2010 - or by 44p a day.

He said: "With escalating fuel prices hitting motorists hard in the pocket, I'm not surprised most are looking for ways to drive down the cost of getting behind the wheel - especially when the cost of insurance cover is on the rise too."

The poll was based on responses from 1,750 people.
