What surface condition of windshield wipers would lead to a failed inspection?

The condition of windshield wipers is crucial for ensuring clear visibility while driving, particularly in adverse weather conditions. Worn or damaged blades that do not provide clear visibility can severely compromise safety, as they may leave streaks, skip over areas of the windshield, or fail to effectively remove water or debris. This lack of functionality can impede the driver's view and increase the risk of accidents. As a result, when wipers are found to be worn or damaged in an inspection, it leads to a failed status, as the vehicle does not meet the safety standards required for operation.

New blades would typically function well and therefore would not fail inspection. Blades that are too long or too short may not directly affect visibility to the same extent as worn or damaged blades; however, they could potentially interfere with the proper operation of the wiper mechanism or be less effective in clearing the windshield. Nonetheless, it is the effectiveness of the wipers' condition that is the primary concern in relation to passing an inspection.
