Christmas is a busy time of the year, with many motorists taking to the roads to drive home over the festive period.
Roads will be busy over the Christmas period, with some congestion and delays expected - but according to the RAC some times are worse than others.
“Thursday 20th and the festive but ‘frantic’ Friday 21st are likely to be some of the worst days with 2.5 million and 2.8 million individual journeys expected to be taken respectively,” said the RAC.
INRIX data scientist Joshua Kidd said: “Our data shows that compared to a normal day, Thursday 20th December will see the biggest increase in cars on the road.
With most drivers setting out mid-morning, traffic will become heavier over the course of the afternoon and stay congested into the evening.”
