Which feature of the vehicle is crucial for weather conditions and visibility?

The functionality of windshield wipers is essential for ensuring visibility in adverse weather conditions. When it rains, snows, or experiences mist, effective windshield wipers help maintain clear visibility for the driver by clearing water, snow, and debris from the windshield. This is critical for safe driving as it allows the operator to see the road and any hazards that may be present.

Additionally, windshield wipers typically have different speed settings and may include features like intermittent operation, which can be adjusted based on the intensity of precipitation. Therefore, checking the condition of the wiper blades, ensuring they are not worn or damaged, and verifying the functionality of the wiper motor is a vital part of the pre-trip inspection process. In adverse weather, if the wipers are not functioning properly, it significantly increases the risk of accidents due to reduced visibility.
