Conditions are treacherous out there. This from the police traffic bureau:
There is heavy snowfall across the county this morning. Please leave plenty of distance from the vehicle in front, clear your vehicle completely of snow if your travel is essential. A19 from Thirsk and York is passable but completely covered with snow at the moment.
