What should you know about using the rear-view mirror?

The chosen combination is correct because it highlights two important aspects of using rear-view mirrors in vehicles:

1. You cannot see vehicles and pedestrians in the blind spot. This is crucial for safe driving, as blind spots can lead to accidents if you're unaware of other road users around you.

2. Rear-view mirrors must be adjusted to the particular driver. Proper adjustment ensures that the driver has the best possible view of the road behind and to the sides, minimizing blind spots and enhancing safety.

These points are in line with German traffic regulations, which prioritize the visibility and safety of all road users. Adjusting mirrors correctly and being aware of blind spots helps prevent collisions and promotes responsible driving behavior.
