What are we required to see in the inner mirror of the vehicle?

1. Correct answer: The surrounding that is seen from the rear windshield and, as much as possible, from both its sides.
2. The passengers in the back seats.
3. The view from the right and left sides of the vehicle.
4. The rear view and the “blind spots” within it.

WhyThe inside mirror should show the whole rear window and, as far as possible, both its sides.
