Why is it essential to check the power steering lines?

Checking the power steering lines is crucial primarily to confirm that they are not cut or rubbing against any components. This is essential because any damage to the power steering lines can lead to fluid leaks, which may result in a loss of steering control. Maintaining proper steering function is vital for vehicle safety, especially in commercial driving, where maneuverability and quick reactions are critical.

While it's important to consider factors such as the age of hoses or their length, these aspects are secondary to the immediate safety implications of ensuring that the lines are intact and properly routed. A line that is rubbing against other parts can wear through, and a cut line can lead to sudden fluid loss, compromising the steering system's effectiveness. Therefore, confirming the integrity of power steering lines is a key step in the pre-trip inspection process to help ensure safe driving conditions.
