Note(s) In this class, the term "vehicle" means all vehicles except those restricted to one of the following types of vehicles: rail vehicles, waterborne vessels, aircraft, space vehicles, hand carts, cycles, animal-drawn vehicles, and sledges; these types are to be found in the relevant classes Fulltext... Hierarchy... Expanded...Fulltext... Hierarchy... Expanded...B61-B64. Thus, the term "vehicle" embraces vehicular characteristics which are common to more than one of the above-listed types.
