When does variable assist power steering provide maximum pressure?

Variable assist power steering is designed to provide different levels of steering assistance based on the vehicle's speed. During low-speed operation, such as when the vehicle is stationary or moving at a very slow pace, the system delivers maximum pressure to the steering components. This heightened assist makes it much easier for the driver to turn the steering wheel, facilitating maneuvers like parking or negotiating tight spaces.

As the speed of the vehicle increases, the assist gradually decreases, providing the driver with more road feel and control at higher speeds. This reduction in assist helps prevent oversteering and maintains stability, which is crucial when driving at higher velocities. Thus, the correct answer emphasizes that the greatest amount of steering assistance occurs at low speeds to aid drivers in critical driving situations where more effort is typically required.
