During an inspection, what part of the windshield wipers should be checked?

The focus of the inspection should be on the condition of the blades and the functionality of the wiper system. This is crucial because the windshield wipers are essential for maintaining visibility during adverse weather conditions, such as rain or snow. Blades that are worn out, cracked, or otherwise damaged can lead to streaking or an inability to clear the windshield effectively, significantly impacting driving safety. Additionally, ensuring that the wiper system functions correctly involves checking that the wipers activate, move across the windshield, and return to their resting position. Proper functionality assures that the driver has a clear line of sight, which is vital for safe operation of the vehicle.

While the length of the wiper arms may be relevant to their ability to reach the entire windshield surface, it is not a direct indicator of their ability to function properly. The color of the wiper fluid doesn’t affect wiper operation or safety and may not provide any relevant information during an inspection. Lastly, the noise level of the wiper motor may indicate potential issues, but it is not as critical as the actual condition of the blades and the operation of the wiper system itself in ensuring that the vehicle remains safe on the road.
