How is the condition of wiper blades assessed during the inspection?

The condition of wiper blades is primarily assessed based on their effectiveness in clearing the windshield without skipping or missing spots. This function is crucial for driver visibility and overall safety, as ineffective wiper blades can lead to reduced visibility during rain or adverse weather conditions. The inspection focuses on how well the blades perform their primary task—ensuring that the driver's line of sight remains clear.

Other factors, such as noise or material type, may indicate wear or deterioration, but they do not directly assess the wiper blades’ core function. If wiper blades make noise, it may signal they are not making proper contact with the windshield, but this is considered secondary to their ability to function effectively. The color of the blades or their material type does not directly affect their performance in clearing the windshield, making them less relevant during an inspection focused on safety and functionality. Therefore, the most critical aspect of evaluating wiper blades is how well they accomplish their job during use.
