#1 It is unlawful to follow a snowplow closer than 200 feet.
It’s illegal (State Statute 346.915) to follow a snowplow closer than 200 feet upon any highway having the posted speed limit of more than 35 mph if the snowplow is engaged in snow and ice removal. The majority of crashes involving snowplows and vehicles happen when a snowplow is rear ended or hit while being passed. Snowplows have wing plow blades that can extend anywhere between 2 and 10 feet beyond the width of the truck. This wing plow blade is often not seen because of the snow cloud being kicked up by the snowplow. These wing plows can often weigh as much as a compact car.

#2 It is unlawful to push snow or other materials onto or across roadways.
It can cause accidents and/or death and is strictly prohibited under Wisconsin Statues 86.01 and/or 346.94(5). Anyone who does not comply will be held responsible for all penalties and liabilities.
