I try to anticipate obstacles (drivers, sweepings corners, etc) in the road. Mostly because other drivers tend to be too confident and I need to be prepared to stop in time if they are losing traction and or are sideways.
If I see a driver acting too confident or who is sliding or gasing it too much then I back way off and stay clear of them.
If possible I try to keep a wheel or two in a clean line (meaning if a track has developed in the road).
Winter tires are a must in my area (PA); not just for the snow, but for the temps and deteriorating roads over the winter. Potholes spawn like crazy this time of year.
