Class Information
Number: 280
Name: Land vehicles >
Description: This class includes vehicles, adapted to travel on land and not elsewhere classified. The term "vehicle" includes some form of running gear as an essential element, which running gear usually supports a load carrier, but may support a load directly, and adapts the vehicle to move over a surface. The basic purpose of those devices commonly called vehicles is the carrying of a load, either freight or passengers, from one place to another. The idea of towing a load, as by locomotives, traction engines, or tractors, has also long been associated with the term "vehicle."
