Which factor is NOT a reason to fail inspection related to the windshield wipers?

The focus of automotive safety inspections is to ensure that vehicles are equipped with functioning components that contribute to safe driving conditions. In terms of windshield wipers, there are established criteria that can lead to a failure during inspection.

When windshield wipers are missing, it directly impacts the driver's ability to maintain visibility during inclement weather, which is a critical safety factor. Similarly, if the wipers do not adequately clear the windscreen, it could result in reduced visibility and an increased risk of accidents. Additionally, wipers that are improperly sized can also affect their performance, leading to streaks or areas of the windscreen that remain uncleaned.

On the other hand, whether the wipers are original equipment is not a qualifying factor for failing an inspection. As long as the replacement wipers function effectively and meet the required performance standards, they can be considered acceptable, regardless of whether they are the original manufacturer's parts. This indicates that operational effectiveness, rather than the brand or manufacturer, is the key criterion for windshield wiper evaluation during an inspection.
