Over the next few days, hundreds of thousands of us will be reliving Chris Rea's classic Christmas hit: Driving Home for Christmas. People from across Wales will be travelling the length and breadth of the country to see family for the festive break, with many continuing on to England, Scotland and further afield.
Of course, with so many travelling to see their loved ones over Christmas, we're going to see a huge number of extra cars on the road - the RAC estimates that between December 19 and December 24, people in the UK will make 19.6 million separate trips to see friends and family, with 40% of all journeys crammed into "frantic" Friday, December 23 and Christmas Eve.
Plus, this year we have Christmas rail strikes to contend with, beginning at 6pm on December 24 and continuing (in the first wave) until 7am on December 27 - causing even more people to travel by car or coach than usual.
