Final answer:
When atmospheric conditions require the use of windshield wipers, it is important to also use windshield washer fluid to clear the windshield.
Step-by-step explanation:
In atmospheric conditions that require the use of windshield wipers, the rain or water on the windshield interferes with visibility while driving. Therefore, it is important to also use the windshield washer fluid along with the windshield wipers. The washer fluid helps to clear the windshield by wetting the glass and facilitating the removal of dirt and water droplets.
