What is the purpose of windshield wipers?

To ensure visibility during rain
To maintain the vehicle's battery
To enhance aerodynamics
To help in nighttime driving

The correct answer is: To ensure visibility during rain

Windshield wipers are essential for maintaining clear visibility during inclement weather conditions, particularly rain. Their primary function is to wipe away rain, snow, dirt, and debris from the windshield, allowing the driver to have an unobstructed view of the road. When visibility is compromised by weather, the risk of accidents increases significantly; therefore, efficient windshield wipers play a critical role in road safety. The other options focus on functions that windshield wipers do not directly serve. Maintaining the vehicle's battery is related to components such as the alternator and battery system, while enhancing aerodynamics pertains to the vehicle's design rather than the function of wipers. Although nighttime driving can also be affected by visibility, windshield wipers specifically address visibility issues primarily caused by weather rather than lighting conditions.
