Traffic today (Saturday, December 20) is expected to be the busiest getaway of any year since the RAC started tracking Christmas travel habits in 2013. Around 37.5 million leisure trips are expected to take place in the week leading up to Christmas Day, smashing last year's 29.3 million trips. The RAC has dubbed today as "Snarl-up Saturday", with 4.1 million trips expected to be taken across the UK as drivers visit friends and family ahead of the festive period. ### LATEST DEVELOPMENTS * BYD overtaken by Jaecoo in 'significant milestone' as British drivers rush to buy Chinese cars * MOT changes confirmed for 2026 as DVSA outlines new rules for testing garages * Petrol and diesel drivers issued two-week warning of Asda fuel station changes ### ### ### The RAC and traffic experts Inrix warn that drivers are likely to face lengthy delays on major roads between 11am and 7pm. Nick Mullender, RAC mobile servicing and repairs team leader, noted that the week leading up to Christmas would be "Grinch-worthy" for those who fail to plan ahead. He continued, saying: "The week before Christmas is one of the few times of year when most of the UK hits the road simultaneously, with 2025 looking to be the busiest getaway period since our records began. "Snarl-up Saturday will be especially busy amid journeys home and the final weekend for gift shopping, but it's midweek Christmas Eve that takes the top spot, suggesting many drivers are saving their precious annual leave and making getaway journeys at the very last moment." ### ### **Our Standards:The GB News Editorial Charter **
