Which part of a motor vehicle is primarily responsible for steering?

The steering wheel is the primary component responsible for steering a motor vehicle. It is the part of the vehicle that a driver uses to maneuver the vehicle in different directions. When the driver turns the steering wheel, it activates the steering mechanism, allowing the front wheels of the vehicle to pivot and change direction. This control is crucial for navigating roads, making turns, and ensuring safe driving.

In contrast, the engine powers the vehicle, providing the necessary force for movement. The brake system is responsible for slowing down or stopping the vehicle, which is essential for safe operation but does not influence steering. The transmission, on the other hand, is responsible for changing the gears of the vehicle to manage speed and power but does not play any role in the direction of the vehicle. Thus, the steering wheel is integral to a driver's ability to control the vehicle's direction.
