During a pre-trip inspection, why is it essential to check wiper blades?

Checking the wiper blades during a pre-trip inspection is crucial primarily because it ensures they clear the windshield effectively. Wiper blades are designed to maintain visibility by removing rain, snow, and debris from the windshield. If the wiper blades are worn or damaged, they might not perform their job correctly, leading to reduced visibility, which can increase the risk of accidents.

Ensuring that the blades clear the windshield effectively means they should be able to make full contact with the glass and move smoothly without skipping or leaving streaks. This functionality is essential for safe driving under various weather conditions. Therefore, inspecting wiper blades contributes directly to the driver’s ability to maintain a clear line of sight while operating the vehicle.
