CDL Class B Pre Trip Inspection Practice Exam

Checking the power steering fluid is essential because insufficient levels can directly impair steering performance and compromise safety. The power steering system relies on hydraulic fluid to assist in moving the steering mechanism. When the fluid is low, it can lead to increased steering effort, reduced responsiveness, and even potential steering failure. This could make it difficult to control the vehicle, especially during maneuvers such as turning or avoiding obstacles, thus creating a hazardous situation on the road.

Ensuring the power steering fluid is at the correct level helps maintain the efficiency of the steering system, allowing for safe and effective vehicle handling. This is a critical aspect of the pre-trip inspection process, as it contributes to the overall safety of the vehicle and those sharing the roadway.
