What can interfere with your view?

You answered completely correctly. In German traffic regulations, your view must always be clear to drive safely. The load can block your view if it is not stowed properly. Worn wiper blades can create streaks, especially in rain, making it hard to see. Smeared windows also reduce visibility. All these factors can interfere with your ability to see the road and react to hazards in time. Always ensure your load is secure and does not block your sight, your wiper blades are in good condition, and your windows are clean before driving.
