Unless you are a forest ranger, a good set of snow tires will be fine. Nevertheless, snow tires or 4WD, you still have to slow down in the winter and drive with caution. Even 4WD vehicles are useless if the snow is too high. Watch intersections, snow and ice tend to accumulate there. This is especially true in rural areas. You could be flying down a relatively clear road and come to an intersection that is covered in snow and ice.
