All truck types fall into one in eight classes as identified by the US government's Gross Vehicle Weighting Rating (GVWR). The GVWR, however, is based on the truck's weight when fully loaded. That means including the passengers, cargo, etc. From small trucks to large tractor trailers, trucks are classifed into three major categories down to eight different classes.
