What is the Best Position to Adjust Rearview Mirrors?
2 Answers
There are three rearview mirrors, and below are the optimal angles for adjusting each: 1. Left side mirror adjustment: Position the horizon line at the center of the mirror, then adjust the edge of the car body to occupy 1/4 of the mirror's image. 2. Right side mirror adjustment: Position the horizon line at two-thirds of the mirror's height, then adjust the edge of the car body to occupy 1/4 of the mirror's image. 3. Central rearview mirror adjustment: Keep it horizontally centered and position your left ear to the left edge. Place the distant horizon line at the center of the mirror, then adjust left and right so that the image of your right ear just touches the left edge of the mirror.
As an experienced driver, I believe that properly adjusting the rearview mirrors can really help avoid a lot of trouble. First, the interior rearview mirror should be positioned at a height and angle that covers the entire rear window, making vehicles and obstacles behind clearly visible and reducing the risk of accidents caused by blind spots. As for the side mirrors, adjust both left and right mirrors so you can see just a little bit of your own car, but the focus should be on clearly seeing the distant road and vehicles to the side—don’t just fixate on your own rear. When used together, this setup ensures seamless visibility during lane changes or reversing, eliminating the need to frequently turn your head to check blind spots. I’ve made it a habit to check the mirrors before driving, maintaining a normal sitting posture with relaxed arms, and adjusting them without tilting my head. Over time, this practice has not only improved safety but also saved me a lot of effort and time while driving.
