How does checking the windshield wipers contribute to safety?

Checking the windshield wipers is crucial for ensuring adequate visibility during adverse weather conditions, such as rain or snow. Windshield wipers play a vital role in clearing the driver's field of vision, allowing for safer driving in situations where visibility is often compromised. If the wipers are worn or not functioning effectively, they may fail to remove water or debris from the windshield, which can lead to impaired vision and increase the risk of accidents.

While aspects like the appearance of the bus or fluid levels are important for maintenance and overall vehicle presentation, the primary safety function of the windshield wipers directly relates to visibility. This makes them an essential component in a pre-trip inspection focused on ensuring the safe operation of the vehicle.
