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

Your answer is correct because in German traffic rules, it is important to know that rear-view mirrors do not show the blind spots where vehicles or pedestrians may be hidden, so you must be cautious and check these areas by turning your head. Additionally, rear-view mirrors must be properly adjusted for the specific driver to ensure clear and optimal visibility of the road behind. The interior mirror does have blind spots, especially on the sides, so it cannot be relied on alone to see everything. Understanding these points helps prevent accidents caused by unseen vehicles or pedestrians.
