In Bottoms v. Southeastern Pennsylvania Transportation Authority, 805 A.2d 47, 48 (Pa. Cmwlth. 2002), the plaintiff ruptured her Achilles tendon when she stepped off a SEPTA bus that had not been kneeled. The Court reiterated the well established requirements that a vehicle, or a part of it, must be in motion for it to be in "operation," and that stationary vehicles from which passengers are alighting are therefore not in operation. Bottoms, 805 A.2d at 49.
