Gross Vehicle Weight Rating Below you will see a break down of the city’s 2010 fleet by classification. The commercial truck classification is based on the gross vehicle weight rating (GVWR) of a particular vehicle. The GVWR is the total weight a vehicle can carry legally, which includes the weight of the truck empty plus the weight of the load it carries.
For example: If a dump truck is 10,000 pounds empty and the GVWR is 15,000 pounds, the truck can carry up to 5,000 pounds. This vehicle would be considered a class 3, 4 or 5 vehicle within our fleet.
