When I turned onto Laketon to go to Hab's Pizza, I was followed by a truck outfitted with a snow plow. Approaching from the west, I noticed another snow plow truck. As soon as I parked, a massive snow plow blasted past the Pizzeria. We live in a snow globe with streets requiring constant clearing by a legion of snow plows.
A snow plow has one powerful motion, charging and moving a bank of snow. The blade can rise, the vehicle can reverse and thankfully stop. All motions prepare a snowplow to execute its prime directive: charge a pile of snow and push pile into a pile out of the way. I'm sure the drivers of snow plows are exceptional people, wonderful parents and good citizens. Behind the wheel, the more snow moved, the better the day. Thus, a snow plow is meant for charging and that is what they'll do and don't make them charge all over you.
Consider the snow plow versus a passenger car. The plow is made of solid metal and is intended to ram snow or snowy ice again and again. The passenger car has never been designed for collisions of any sort, despite the fact that most passenger cars are equipped with bumpers. Cars colliding into other cars in a demolition derby are a notable exception, and those cars are driven by auto mechanics who do their own body work. Betting that most demolition derby drivers are snow plow drivers during the snowy season. Bottom line is give those snow plows a wide berth as car versus snow plow is always won by the snow plow. Hence is the basis of snow plow law. If a snow plow charges your way, move rapidly. Snow plow, like a Honey Badger, don't need to care.
