What is the correct position to adjust car rearview mirrors?

[VanIsla]

Correct adjustment positions for car rearview mirrors: 1. For the left mirror, one-quarter of the car body should be visible, with the horizon positioned at the center of the mirror; 2. The right mirror should also show one-quarter of the car body, with the sky occupying one-third and the ground two-thirds of the view; 3. The interior rearview mirror should divide the view equally between sky and ground (half each), providing clear visibility of the rear through the window. Rearview mirrors are crucial safety components of motor vehicles, used for observing rear road conditions during reversing and monitoring the vehicle's surroundings while driving. Currently in China, most automotive rearview mirrors use silver or aluminum for their reflective coating, with some models using chromium.
