What are the side effects of using malfunctioning windshield wipers?
- Damaging the vehicle’s engine.
- Causing noises in the sound system within the driver’s compartment.
- Correct answer: Impaired windshield visibility, as well as windshield damage.
- Damaging the windshield’s sealing.
Why this is the answer
The correct answer in the official bank: Impaired windshield visibility, as well as windshield damage.
Worn or faulty wipers do not clear the windshield properly and leave streaks, smears and uncleaned areas, so visibility through the glass drops, especially in rain and at night. Hardened or cracked rubber, and especially a bare metal arm, can also scratch and damage the windshield. Wipers have no effect on the sound system or the windshield sealing, so they should be replaced when worn.
