What condition must windshield wipers be in to pass inspection?

Windshield wipers are a critical safety feature on a vehicle, directly impacting visibility during inclement weather. To pass inspection, they must be in good working condition, meaning they can effectively clear the windshield of rain, snow, or debris without leaving significant streaks or obstacles to the driver's view. This condition ensures that the driver has optimal visibility, thereby enhancing safety on the road.

While there may be standards for how often wipers should be replaced or maintained, as well as allowances for minor wear, the key requirement during inspection is their functionality and effectiveness in providing a clear line of sight. The other options do not address the critical need for the wipers to operate properly and efficiently to meet safety standards. Therefore, the focus on good working condition and effective clearing capability is the primary requirement for passing inspection.
