In Swartz v. Hilltown Township Volunteer Fire Co., 721 A.2d 819 (Pa. Cmwlth. 1998), the Court held that the vehicle exception did not apply when a five-way diverter valve fell off the back of a Township fire engine causing a car accident. Stated otherwise, the movement of a vehicle, or its parts, that is merely ancillary to that vehicle's normal operation does not trigger the motor vehicle exception. Swartz, 721 A.2d at 822.
