Yeah same here, I came into York from Leeds (Bramley) and had to almost dig the car out and skidded and slipped all the way I took me 3 and a half hour to get to work this morning ! 30 mile journey.
York its self isn't bad at all not even an inch of snow, Leeds was like 4 times as bad. Doesn't really take much for the road network to buckle around York.
A1237 was like a car park and the A64 wasn't really much better.
