What is the function of inspecting wiper blades during a pre-trip inspection?

Inspecting wiper blades during a pre-trip inspection is essential for ensuring they clear the windshield effectively. This function is crucial for maintaining visibility while driving, particularly in adverse weather conditions such as rain or snow. Worn or damaged wiper blades may fail to remove water or debris from the windshield, which can significantly impair the driver's vision and increase the risk of accidents.

While factors like the overall age and appearance of the wiper blades can be indicators of their effectiveness, the primary concern during the inspection is their operational capability to provide a clear view of the road. Therefore, it's vital that the wiper blades are in good condition and functioning properly to ensure safety.
