On interurban roads, those pushing or pulling a two-wheeled cycle or moped, hand carts or similar devices, any group of pedestrians led by a person or forming a procession, and disabled persons travelling in wheelchairs must always walk on their right, and all of them must obey the signals directed to vehicle drivers: those of officers and traffic lights, always; the others, insofar as they are applicable to them.
