The correct answer is B — Mobile equipment endorsement. A forklift is ordinarily classified as mobile equipment, rather than an “auto,” because it is principally designed for use off public roads or for operations at a premises. Consequently, it does not automatically fall within the standard Business Auto Coverage Form's normal treatment of covered autos.
A Mobile Equipment endorsement permits specifically described mobile equipment to be treated as a covered auto for the coverages scheduled in the endorsement. Depending on the form and selections, this can extend Physical Damage coverage to the equipment. Forklifts are specifically recognized as classic examples of mobile equipment.
The Miscellaneous Type Vehicle endorsement is primarily associated with personal auto treatment of specialized vehicles and is not the appropriate commercial solution here. The Truckers Coverage Form addresses motor-carrier/trucking exposures. The Drive Other Car endorsement extends specified commercial-auto protections to certain individuals when they use nonowned autos and has nothing to do with insuring a business-owned forklift.
The Series 17-70 outline directly tests Commercial Auto, Business Auto, Physical Damage Coverage, Definitions, and the Mobile Equipment endorsement. The New York examination outline identifies mobile equipment specifically among the selected commercial-auto endorsements.
Thus, B is the technically correct selection.
