I'm curious though, how do they expect a truck driver to remove snow from the top of a semi truck? The trailer is 13' 6" high, placing a ladder on an icy parking lot to climb on top seems like a bad idea. The roof on many trailers is thin fiberglass, not nearly strong enough to stand on. The metal roofs are made from very thin aluminum, it will be very easily damaged by standing on it. How should a truck driver go about clearing the snow from the roof of his trailer? Can anyone think of a safe a practical way of doing this?
