Which components should be demonstrated and checked for the wipers during the pre-trip inspection?

The correct choice emphasizes the essential aspects of the windshield wipers that must be evaluated during a pre-trip inspection to ensure the vehicle operates safely and effectively. Each of these components serves a critical function in the overall operation of the wipers.

First, confirming that the wipers are securely attached prevents any operational failures while driving, which could lead to dangerous visibility issues. Smooth operation is vital, as any jerky or inconsistent motion could indicate worn-out components or damage that needs replacement. Additionally, inspecting for any visible damage, such as cracks or tears in the rubber blades, ensures that the wipers will effectively clear water and debris from the windshield.

Checking the presence of windshield washer fluid is equally important. Inadequate fluid levels can hinder the ability to clean the windshield during adverse weather conditions, significantly impacting visibility and safety.

By focusing on these aspects, the pre-trip inspection confirms not only that the wipers are functionally sound but also that they allow the driver to maintain a clear view of the road, which is imperative for safe driving.
