Final answer:
If the power-steering system fails in a vehicle, it becomes difficult to steer the vehicle. This can be dangerous, especially at low speeds or when making tight turns. It is important to remain calm and pull off the road to a safe location as soon as possible.
Step-by-step explanation:
If the power-steering system fails in a vehicle, it becomes difficult to steer the vehicle, especially at low speeds or when trying to make tight turns. This is because the power-steering system assists the driver in turning the wheels by using hydraulic pressure created by the power-steering pump. When the system fails, the steering effort required increases significantly, making it challenging to maneuver the vehicle.
For example, if the power-steering system fails while driving at a high speed, the vehicle can still be steered, but the steering wheel will feel heavier, and it will require more strength to turn the wheels. On the other hand, if the power-steering system fails completely, the steering wheel may become difficult to turn at all, making it nearly impossible to control the direction of the vehicle.
Therefore, it is crucial to remain calm and keep both hands on the steering wheel if the power-steering system fails. Slow down gradually and pull off the road to a safe location as soon as possible, using both arms to steer the vehicle with more force.
