A driver is the person who operates the steering mechanism or is in command of a vehicle. In vehicles being driven during practice sessions, the driver is the person in charge of the dual controls, i.e., the driving instructor. A person who walks a motorcycle is also considered a driver. However, a person who walks a two-wheeled cycle or moped on foot is considered a pedestrian.
