When the car image occupies two-thirds of the rearview mirror, the distance is 5 meters; 3. When the image occupies half of the rearview mirror, the distance is 9 meters; 4. When the car image occupies one-third of the rearview mirror, the distance is 12 meters; 5. When the lower edge of the front windshield aligns with the upper edge of the rear bumper of the car in front, the distance is 1 meter; 6. When the lower edge of the front windshield aligns with the lower edge of the rear bumper of the car in front, the distance is 2 meters; 7. When the lower edge of the front windshield aligns with the lower edge of the rear tire of the car in front, the distance is 3 meters. Rearview mirrors are located on the left and right sides of the front of the car and at the front of the car body. They are important safety components, and their function is to allow the driver to indirectly see the conditions behind, beside, and below the car, thereby expanding the driver's field of vision.
