This class includes vehicles, adapted to travel on land andnot elsewhere classified. The term "vehicle" includessome form of running gear as an essential element, which runninggear usually supports a load carrier, but may support a load directly,and adapts the vehicle to move over a surface.

The ideaof towing a load, as by locomotives, traction engines, or tractors,has also long been associated with the term "vehicle."
(1)Note. The term "vehicle" also includes devicesthat are for special purposes identical with those in which a formof running gear is an essential element, and further includes suchattachments for vehicles as are not limited in their position toany particular part of the vehicle.
(2)Note. This class includes the combination between runninggear and load carriers not otherwise classified.
(3)Note. The running gear of various portable machines is alsoincluded when the machine is not claimed or is claimed by name onlyand the running gear is capable of general use. However, when theclaimed running gear is solely disclosed for an agricultural, earthworking, or harvesting implement, proper classification is in the appropriateagricultural, earth working, or harvesting implement class, evenwithout specific claimed limitations of such agricultural, earthworking, or harvesting implement. See the class definition (Class280), EARTH OR TRAVELED SURFACE, TRAVERSING AND WORKING OR TREATINGDEVICES,and also subclass 400 herein,the (1) Note, directed to an articulated vehicle or plural interconnected vehicles(i.e., a vehicle train).
(4)Note. The relationship of vehicles which are primarily intendedfor transportation purposes to working devices of various types,which may or may not travel while performing their primary function,and to various related arts is discussed in the following searchnotes presented in the sequence of the following "OUTLINEOF NOTES."
