A steering wheel is a circular device used to control the direction of a vehicle, such as a car or truck. It is typically located in front of the driver's seat and is connected to the vehicle's steering mechanism. When the driver turns the steering wheel, it causes the front wheels to pivot, allowing the vehicle to change direction. Most steering wheels are designed with grips for better handling and may include buttons for various functions, such as audio controls or cruise control. The design and size of a steering wheel can vary depending on the type of vehicle, including sports cars and SUVs.
