What generally needs to be verified about a vehicle’s windshield wipers during inspection?

The verification of a vehicle’s windshield wipers focuses on their operational capability, which includes ensuring they move smoothly without any skipping or hesitation. This is essential for the safety of the driver and passengers, as effective windshield wipers improve visibility during adverse weather conditions, such as rain or snow. Wipers that skip or do not function properly can leave streaks on the windshield or fail to clear water effectively, potentially leading to dangerous driving situations.

The other options either do not pertain to functionality or present conditions under which the wipers are checked. For instance, the color of the wipers is irrelevant to their performance, and functionality should be assessed regardless of weather conditions. Regular inspections ensure that these critical safety features are in proper working order at all times, not just when it is actively raining.
