Describe the function of the power steering system in a school bus.

The power steering system in a school bus is designed to reduce the effort needed to steer the vehicle. It achieves this by utilizing hydraulic or electric systems that amplify the driver's input on the steering wheel, making it easier to maneuver the bus, especially considering its size and weight. This functionality is crucial for maintaining control and ensuring safety while driving, particularly when navigating tight spaces or making sharp turns.

While other systems may play a role in aspects like stabilizing the vehicle in windy conditions or aiding in braking, these are not the primary purpose of the power steering system. The focus of the power steering is solely on enhancing steering ease, allowing drivers to operate the bus with greater comfort and precision.
