What is the main reason for checking windshield wipers during inspection?

The primary reason for checking windshield wipers during an inspection is to ensure visibility during inclement weather. Windshield wipers play a crucial role in maintaining clear sightlines for the driver by removing rain, snow, and debris from the windshield. Properly functioning wipers help prevent accidents by ensuring that the driver can see the road and any obstacles clearly, especially in poor weather conditions where visibility can be severely compromised. If the wipers are worn out, damaged, or ineffective, they may not adequately clear the windshield, leading to dangerous driving situations. This emphasizes the importance of keeping wipers in good working condition as part of vehicle safety inspections.
