I just follow far enough back (good old "two second rule") that there's plenty of room for anything that falls off the vehicle in front of me to hit the ground before I get to it.
Of course, that leaves an opening for others to cut across three lanes in the gap ahead of me - but that's all right, they can take the ice hits.
