The term 'steering apparatus' refers to the various components that are used to control the direction of a vehicle. The most common steering apparatus is the HELMS, which is a five-letter word. The HELMS is a device that is connected to the steering wheel and is used to turn the wheels of the vehicle in the desired direction. Other steering apparatus include power steering systems, hydraulic systems, and electronic systems. All of these components work together to provide the driver with the ability to control the direction of the vehicle.
