Today is expected to be the busiest day for traffic over the festive period as millions of people embark on the Christmas getaway.
The AA predicts about 12 million cars will be on the roads due to a combination of people visiting loved ones, shopping trips and holidays, as well as those travelling to and from work.
It commissioned a poll of more than 19,000 motorists which found that 41 per cent expect to drive more than 20 miles on Friday.
AA patrol of the year John Snowling said: ‘On Friday, it’s likely to be very busy at peak times on the major routes as the Christmas getaway coincides with commuter traffic.
‘With Christmas falling on a weekend, many people will start their break from Friday, but almost a third of our members will be making their journey on Saturday and more than a fifth will be travelling on Christmas Day to visit friends and family.’
It’s despite an earlier report by traffic information supplier Inrix which predicted that 4pm on Friday December 16 would be the busiest time on the roads during the festive period.

Green Flag’s head of rescue Neil Wilson said: ‘Many people will be hitting the roads to visit family and friends, and with adverse weather conditions it’s important to ensure you have carried out the relevant car safety checks in order to avoid car faults and breakdowns.’
