The term 'steering wheel' is often referred to as a 'HELM' in nautical terms. A HELM is a device used to steer a ship, boat, or other watercraft. It is usually located at the stern of the vessel and is operated by a person known as the helmsman. The HELM is connected to the rudder, which is used to control the direction of the vessel. In modern times, steering wheels are used in cars, trucks, and other land vehicles to control the direction of the vehicle.
