What should be checked for proper operation during the inspection of a vehicle?

During a vehicle inspection, it is essential to check the windshield washers for proper operation because they play a crucial role in maintaining visibility while driving. Clear visibility is a key factor in road safety, and functional windshield washers contribute significantly to this by ensuring that the windshield can be cleaned of debris, dirt, and water. Given that poor visibility can lead to accidents, state regulations prioritize the functionality of essential safety components like windshield washers during inspections.

In contrast, while items such as air conditioning, power windows, and upholstery condition may affect the comfort and convenience of the vehicle, they are not critical to the immediate safety of the vehicle on the road. Therefore, checking the windshield washers is more directly related to vehicle safety, making it a priority during inspections.
