DEFINITION
Classification: 280/86.5
Auxiliary axle assembly (e.g., lift or tag axle):
(under subclass 80.1) Subject matter wherein the vehicle includes a selectively employed supplemental running gear unit to assist primary running gear units when transporting an extra heavy or oversize load.
(1) Note. The supplemental running gear unit must be movable between a use and nonuse position upon the vehicle, not merely an additional running gear unit such as commonly known tandem axles or wheels.
