How does the inspection of windshield wipers contribute to safety during a pre-trip inspection?

The inspection of windshield wipers is crucial for ensuring proper visibility during adverse weather conditions, which directly contributes to safety on the road. Windshield wipers are designed to clear rain, snow, and debris from the windshield, allowing the driver to see clearly and react appropriately to the driving environment. When wipers are functioning correctly, they provide a clear line of sight, minimizing the risk of accidents caused by reduced visibility.

While other aspects, such as fuel efficiency or aesthetic appeal, may be relevant in different contexts, they do not directly impact the essential function of safe driving like the wipers do. Additionally, while preventing windshield scratches can be a consideration, it does not take precedence over the immediate necessity of maintaining visibility, especially in challenging weather.
