What is the purpose of checking the fluid in the wipers?

The primary purpose of checking the fluid in the windshield wipers is to ensure they are functioning properly. Windshield wiper fluid plays a critical role in maintaining visibility while driving, as it helps to clear dirt, debris, and other obstructions from the windshield. If the fluid is low or empty, the wipers might not operate effectively or clean the glass adequately, which can compromise safety on the road. Proper fluid levels ensure that the wipers can effectively perform their job, allowing for clear vision in various weather conditions.

In contrast, while checking for leaks, assessing brand consistency, or maintaining aesthetics may have their places in overall vehicle maintenance, they do not directly relate to the safety and functionality of the wiper system in the same critical manner. The functionality and effectiveness of the wipers are of utmost importance, making the fluid check essential for safe driving.
