There are several reasons that the plows operate at slower speeds. At slower speeds, the plow operator is able to clear the lanes more effectively. During a snow event, our plow operators are monitoring several different conditions at one time. The operator is attempting to try to clear as closely to the center line as possible and may occasionally cross the center line due to decreased visibility. This leaves a very slim margin of error.
The operator must also pay attention to the need to distribute sand/salt as needed as well as monitor oncoming traffic, mailboxes, and other obstacles that may come up. The operator is required to do this during a time of severely reduced visibility.
