Power steering is a system that facilitates handling of the steering wheel, especially at low speed. In situations where slow manoeuvring is required, such as when parking or driving in areas with heavy traffic, power steering reduces the force needed to move the steering wheel to a minimum. This makes it easier and more comfortable for the driver to turn the steering wheel without excessive effort.

- Low speed: Under these conditions, the power steering system is designed to provide maximum assistance, making the steering wheel lighter and easier to turn.

Therefore, power steering is especially useful at low speed, as it minimises the physical effort required to manoeuvre the vehicle.
