Motorists planning to visit family and friends over Christmas are being warned to brace themselves for some heavy traffic conditions.
The RAC is predicting that up to 13 million people will take to the roads between Christmas Eve and Boxing Day, with Britons spending an estimated total of £2 billion on travel over the holiday period.
It is advising motorists toplan their journey carefully and ensure their cars are in good working order.
Traffic information firm Inrix predicts the M25 will be the UK's most congested route with traffic at its busiest between noon and 5pm on Friday, December 20.
It is warning that journey times could triple during some peak periods with areas around shopping centres being particularly busy during the weekend before Christmas, and on December 27.
Meanwhile, a survey by manufacturer Kia predicts the average family car will be driven 413 miles over Christmas, with 10% of motorists admitting they'll probably make over 11 separate journeys to stock up on food.
Areas around UK airports and the Channel Tunnel are also likely to be busy with an estimated four million Britons planning to head overseas for a Christmas or New Year break this year.
