An articulated bus, also referred to as a bendy bus, tandem bus, stretch bus, or an accordion bus, is an articulated vehicle used in public transportation. It is usually a single-decker, and comprises two or more rigid sections linked by a pivoting joint (articulation) enclosed by protective bellows inside and outside and a cover plate on the floor. This allows a longer legal length than rigid-bodied buses, and hence a higher passenger capacity, while still allowing the bus to maneuver adequately.
