What is the appropriate position for adjusting the right side mirror?

[MacVincent]

When adjusting the right side mirror, it is important to minimize the visible space occupied by the sky. The horizon should be positioned at two-thirds of the mirror's height, and the edge of the car body should occupy one-fourth of the mirror's image. The specific adjustment method is as follows: First, sit in the driver's seat in your usual driving posture. Use the mirror control button to adjust the left mirror vertically until the sky and ground each occupy about half of the mirror. Then, adjust the mirror horizontally. Ensure that the rear of the car occupies about one-fourth of the mirror (try not to exceed one-fourth). The right side mirror can be adjusted using the same method as the left. This allows you to observe the driving path of distant vehicles behind you while also keeping track of the rear of your car when reversing. If you cannot see the rear wheels when reversing, you can purchase a pair of small convex mirrors and attach them to a suitable position on the side mirrors.

Adjusting the position of the right side mirror, I think the key is to ensure it minimizes blind spots while allowing you to clearly see the side and rear situation. First, park the car in a safe place and sit in the driver's seat with a normal posture. Typically, I adjust it like this: make sure the rear part of the car occupies only about a quarter of the mirror's space, with the remaining portion primarily capturing the road and passing vehicles. This way, when a car passes by, it won’t suddenly disappear from the blind spot—for example, when emerging from your visual dead zone, the mirror can promptly display it. Avoid adjusting the mirror too far inward toward the car body, as that will only show the rear of your own vehicle and make it easy to overlook side hazards. Similarly, don’t adjust it too far outward, as it may distort the road view. My advice is to test it repeatedly: for instance, while parked, adjust the mirror and then slowly move your head to check the effect. On the highway, if you can easily see the movement of vehicles in the overtaking lane behind you, the position is correct. This not only helps prevent accidents but also reduces the need to turn your neck frequently, minimizing driving fatigue. In short, safety comes first, and spending extra time adjusting is well worth it.

As someone who drives year-round, let me share a practical tip: When adjusting the right-side mirror, I make it a habit to sit up straight first, hold the steering wheel normally, then adjust the mirror so that I can just barely catch a glimpse of the rear wheel, leaving most of the space for road visibility. This way, when a vehicle behind or a pedestrian on the roadside approaches, I can react promptly to avoid blind spot conflicts. If the mirror is positioned too high, it forces you to look down, increasing distraction; if it's too low, the view is obstructed by the car body, making it hard to see anything. I believe the adjustment method is similar for regular sedans, but when driving an SUV, you need to angle it slightly more outward due to the larger blind spots caused by the higher vehicle height. After parking, I usually double-check—for example, taking a photo of the mirror angle before getting in the car for comparison. Remember, this adjustment isn’t a one-time thing; you’ll need to readjust whenever there are changes in seat height or load. Simply put, the goal is to ensure you don’t have to frequently turn your head while driving, allowing for a natural transition in your field of vision.

When I was learning to drive, my instructor always reminded me of the importance of the right-side mirror. Now, I stick to a simple method: after adjusting my seat, I turn the mirror until only a small edge of the car's rear is visible, with the rest fully showing the side of the road. This eliminates that annoying blind spot, so motorcycles or small cars won't suddenly appear and startle you when they get close. After adjusting, I do a quick test: I glance sideways to ensure the mirror covers the movement of vehicles behind me. If the view feels unclear, I fine-tune the mirror angle. Beginners shouldn’t rush the adjustment—setting it too inward makes it hard to see what’s behind, while too outward distorts the image. My advice is to practice in an open area first, not on busy roads.
