I have been a trucker for over twenty years, so please ask why we drive a certain way in the winter if you want to know.

Example: A long steep icy hill, and you see a transport going slow up this hill in the passing lane.
You might think why is that idiot going slow in the passing lane, up this long hill?
Answer: That is where most of the traction sand is, and if he was in the slow lane he would spin out, block the lane, and then have to put chains on.
