The steering wheel is used in most modern land vehicles, including all mass produced cars, light and heavy trucks. The steering wheel is the part of the steering system that is directly affected by the driver; the rest of the system responds to driver-like inputs. This can be direct mechanical contact as in a ball-nut or rack-and-pinion mechanism, without or with power steering, or as in modern vehicles with computerised actuators known as electric power steering.
The steering wheel for passenger cars is usually round and mounted on the steering column in a hub attached to the outer ring of the steering wheel with one or more spokes (single-spoke is a rather rare exception). Other classes of car may use a butterfly shape or something else. In left-hand drive countries, the steering wheel is usually on the right-hand side of the car (right-hand drive layout); in right-hand drive countries, the opposite is true (left-hand drive layout).
Since the driver may be behind the wheel for many hours, the steering wheel is designed with ergonomics in mind. More important, however, is the task of efficiently transmitting the driver's torque to the steering wheel, which is particularly important where power steering is not available or in those rare cases where control is lost. Typically, steering wheels are made from steel or aluminium with plastic or rubberised grip surfaces moulded over or around them. Some drivers order vinyl or fabric steering wheel covers to increase grip or comfort or simply to improve appearance. Another accessory that serves to make steering easier is an additional handlebar.
