What can interfere with your view?

You correctly identified all factors that can interfere with your view while driving. According to German traffic rules, your visibility must always be clear. The load on your vehicle (1) can block your line of sight either directly or by causing instability that affects control. Worn wiper blades (2) reduce the effectiveness of clearing rain or dirt, leading to streaks that blur your vision. Smeared windows (3) cause light to scatter, making it harder to see, especially in direct sunlight or at night. Ensuring none of these issues are present helps maintain safe driving by guaranteeing a clear field of vision.
