Typically we refer to them as 'plows' or 'snowplows' in the US midwest regardless of what they're actually doing—they often (but not always) have a large plow on the front, and a salt/sand spreader on the back, or in some cases a sprayer that shoots out fine mist that gets your car all grimy and nasty for the next day or two.

The mist is called "brine", at least here in DC metro. It's usually applied before a winter weather event. Once the snow is down, we apply a normal salt/sand mix.
