If I noticed a snow plow coming up behind me I would pull over to the other side of the road and wait for it to pass. Travel is much easier behind the plow. Watch out for ise at traffic lights as braking and accelerating cars seem to pack and polish the snow. With new snowfalls I found it easier to ride in the virgin snow on the sidewalks than try to negotiate the ruts made by the cars. For a period I used a cheap folder 3 sp for the winter and I found the short wheelbase made handling a lot easier on ice and in the ruts.
