Abstract: A plurality of flexible flaps are arranged in a row inward of a handicap entrance door of a bus. The flaps may be attached to the ceiling of the bus. The flaps may be similar to those seen in industrial freezer entrances. The entrance is permitted to remain effectively closed during the process of picking up or dropping off a handicapped student, except for the moment when the student passes through the flaps to enter the school bus, thus preventing uncomfortable temperature changes for other students in the bus.
