What must wiper blades do during inspection?

1. Clean the windshield in any weather

2. Effectively clear the windshield without streaks

3. Change speed automatically in the rain

4. Be made of rubber only

The correct answer is: Effectively clear the windshield without streaks

Wiper blades must effectively clear the windshield without streaks during inspection to ensure optimal visibility for the driver. This requirement is crucial for maintaining safety on the road, as any obstruction to the driver's view can lead to hazards. The presence of streaks indicates that the blades are either worn out or not functioning correctly, which could compromise the effectiveness of the wipers in removing water or debris from the windshield. The focus on effectiveness and clarity is also tied to passing the safety inspection standards. Wipers that leave streaks may not clear water efficiently, potentially leading to dangerous driving conditions, especially during rain. Therefore, inspectors prioritize wiper blades that function properly and provide a clear view. Wiper blades being made of rubber only is not a decisive factor, as there are various materials used in the construction of wiper blades, including silicone and other composites, which can also be effective. Automatic speed adjustments based on the rain also is a feature found in certain vehicles but is not a requirement during inspection for all vehicles. Similarly, the ability to clean the windshield in any weather is not practical since wiper performance can vary depending on conditions, but the essential requirement is that they clear the windshield reliably when needed.
