What is the method for adjusting car rearview mirrors?

Car rearview mirror adjustment method is: 1. Left rearview mirror: Place the horizontal line at the center line of the rearview mirror, then adjust the edge of the car body to occupy one-fourth of the mirror image; 2. Right rearview mirror: Place the horizontal line at two-thirds of the rearview mirror, then adjust the edge of the car body to occupy one-fourth of the mirror image. The method for judging the distance between cars by looking at the rearview mirror is: 1. Take the center of the rearview mirror as the reference line. When the car body is on the outer side of the reference line and the rear car cannot be fully seen, the distance is 5 meters; 2. When the rear car can fully appear in the rearview mirror and the car body is pressed on the reference line, the distance is 10 meters; 3. When the rear car is pressed on the central axis of the rearview mirror, and there is still a car width between the car in the rearview mirror and the outer edge of the rearview mirror, the distance is 15 meters.
Adjusting the car mirrors after getting in is crucial as it eliminates blind spots and ensures safety. I always adjust them properly before driving, and the method isn’t complicated: First, sit in the driver’s seat in your normal posture without moving your body, then adjust the interior rearview mirror until the entire rear window is visible, with the sky and ground each occupying half. Next, adjust the left side mirror by turning it while observing until only a small portion of the car’s side is visible, leaving most of the road clearly in view. The right side mirror follows the same principle, with the key being to position the horizon in the middle of the mirror. Remember to test the adjustment by leaning slightly toward the left window—if the previously hidden car in the blind spot becomes visible, the adjustment is successful. Don’t skip this step—it takes just a few minutes but significantly reduces the risk of rear-end collisions or accidents while turning, especially during nighttime driving or in heavy traffic when blind spots are particularly dangerous. Additionally, a clear mirror view makes reversing much easier and safer.
