Cheapest fuel in a decade drives US holiday weekend

American drivers take to the roads this holiday weekend enjoying the lowest fuel prices for a decade. On Friday, the average price of a US gallon of petrol (3.7 litres) was $2.31 - 40 cents lower than the same time last year.

Although oil prices are beginning to rise, briefly going above $50 a barrel on Thursday, fuel remains cheap. As many as 38 million Americans are expected to drive over the Memorial Day long weekend. Monday's holiday is considered the unofficial start to the summer season.

The number of drivers on the road is expected to be the highest since 2005.

A survey by the American Automobile Association (AAA) found 55% of drivers said they were more likely to take a trip due to the low fuel prices. "The great American road trip is officially back thanks to low gas prices, and millions of people from coast to coast are ready to kick off summer with a Memorial Day getaway," said AAA's chief executive Marshall Doney.
