Low-floor buses usually include an area without seating (or seating that folds up) next to at least one of the doors, where wheelchairs, walkers, strollers/prams, and where allowed even bicycles, can be parked. This is sometimes not the only purpose of this area, though, as many operators employ larger standee areas for high occupancy at peak times. Despite the space existing, operators may also insist that only one or two wheelchairs or pushchairs can be accommodated unfolded, due to space/safety concerns.
