The correct method for adjusting car rearview mirrors is: 1. Adjust the horizon image in the left rearview mirror to the center of the mirror; 2. Adjust the image of the left side of the car to occupy one-fourth of the right side of the mirror; 3. Adjust the horizon image in the right rearview mirror to two-thirds of the mirror's height; 4. Adjust the image of the right side of the car to occupy one-fourth of the left side of the mirror. The function of car rearview mirrors: To reflect the situation behind, beside, and below the car, allowing the driver to indirectly see these positions clearly, expanding the driver's field of vision, and increasing the safety of reversing and driving.
I've been driving for almost ten years, and I believe the key to adjusting rearview mirrors is ensuring maximum visibility and safety. After settling into your seat, first adjust the interior rearview mirror to face the rear window squarely, making sure the entire glass is in view without blind spots. Then for the left side mirror, I lean slightly toward the window, manually or with buttons, until I can see a bit of the car's door handle and the junction point with the road behind. The right side is similar, but adjust the handle slightly higher due to the wider viewing angle. After adjustment, check blind spots—if a car approaches from the side rear, it shouldn't disappear completely, otherwise accidents can happen during turns or lane changes. Many people get the angles wrong, adjusting too far outward or inward, losing partial visibility and causing frequent lane-change mishaps. I check mine weekly, especially before long trips, ensuring the mirrors are clean and stable. In rain or at night, fine-tune to reduce glare. Electronic mirror models adjust with buttons, but manual ones on older cars require more patience. Make it a habit—it saves trouble, don’t wait until a scrape happens to regret it.
