The windscreen wipers do not wipe clean? What can be the reason for this?

When it comes to windscreen wipers not functioning effectively, it's important to understand the factors that can contribute to this issue according to German traffic regulations.

First, worn wiper blades can lead to inadequate contact with the windscreen, causing poor visibility in rain or other conditions. This can pose a significant safety risk, as clear visibility is essential for safe driving.

Second, an oil film on the windscreen can interfere with the wipers' ability to clear water, resulting in streaks and reduced clarity. Maintaining a clean windscreen is critical for ensuring optimal visibility and compliance with traffic safety laws.

The third option, a defective windscreen heating system, can also contribute to reduced visibility by failing to clear fog or ice effectively. If the heating does not work, it can exacerbate visibility issues, especially during colder months.

Choosing multiple correct answers is crucial because all these factors can independently or collectively impact your driving safety. German traffic laws emphasize the importance of maintaining your vehicle's components, including wipers and windscreens, to ensure safe travel.
