- A Steering knob is a knob that attaches to the steering wheel of an automobile.
- The knob swivels, and is intended to make steering with one hand less difficult.
- Their main use today is still in trucks, particularly semi-trucks. They are also used on forklifts, riding lawnmowers, and ice resurfacers, where frequent sharp turning is required.
- The knob is also standard equipment in most modern farm and commercial tractors
