How smooth should the operation of the windshield wipers be?

The operation of the windshield wipers should be consistent and smooth to ensure optimal visibility for the driver. When the wipers function effectively, they clear water, debris, and other obstructions from the windshield without leaving streaks or causing distraction. Smooth operation is crucial, as jumpy or erratic wipers can hinder vision and increase the risk of accidents, especially in adverse weather conditions. Slow and labored movement can indicate a potential issue with the wiper motor or linkage, while claiming that the operation depends solely on weather conditions overlooks the necessity for the wipers to function properly under all circumstances to maintain safety while driving. Maintaining the windshield wipers in a consistent and smooth operation is thus vital for safe driving practices.
