Drivers have even been advised to consider waiting until Christmas day to travel unless it is absolutely necessary.
RAC patrol manager David Hoares told BBC Scotland: "Our advice continues to be - you really must check your local weather and the traffic situation where you live and where your journey is going to before you decide whether you have to travel.
"Our basic advice is for people to delay their journeys as much as possible, or even maybe if you were going to travel Christmas Eve look to travel on Christmas Day because the weather is improving."
