There are three reasons why you might see plows on the streets on snowless days. One is that every driver undergoes pre-season training. Skills must be sharpened and routes need to be learned and relearned. The second reason
is that the trucks may be scanning for secondary cleaning (cleaning the streets where vehicles were parked during the plowing of the streets). The third reason is that the trucks can be salting ice condition areas that are out of their view, or other problem areas.
