How to Determine the Distance of the Rear Vehicle Using Car Rearview Mirrors?

[DanielaLee]

Methods for determining the distance of the rear vehicle using car rearview mirrors are as follows: 1. If the rear vehicle is located on the outer side of the rearview mirror, it indicates a closer distance; if it is on the inner side, it indicates a farther distance. 2. The larger the rear vehicle appears in the rearview mirror, the closer it is; the smaller it appears, the farther it is. 3. When the internal rearview mirror shows the rear vehicle's hood but not its grille, the distance is approximately 3 meters. 4. When the internal rearview mirror shows the rear vehicle's grille, the distance is approximately 8 meters. 5. When the internal rearview mirror fully shows the rear vehicle's wheels, the distance is more than 20 meters. Car rearview mirrors are crucial safety components, serving to indirectly provide the driver with a clear view of the rear, sides, and underside of the vehicle, thereby expanding the driver's field of vision.
