How to Judge the Distance of the Interior Rearview Mirror?
3 Answers
Methods for judging the distance of the interior rearview mirror (varies slightly depending on the vehicle model): 1. When the rear vehicle's grille is completely obscured: The distance between the rear vehicle and the front vehicle is 3 meters. At low speeds, this distance is still considered safe. If the speed is higher, accelerate or change lanes to avoid getting too close to the rear vehicle. 2. When the rear vehicle's front bumper is completely obscured: The distance between the rear vehicle and the front vehicle is 8 meters. If the speed is higher, accelerate or change lanes to maintain a sufficient safe distance from the rear vehicle. 3. When the lower edge of the rear vehicle's tires is visible: The distance between the rear vehicle and the front vehicle is 23 meters. At this distance, the safe speed is approximately 25 km/h.
I adjust my car's rearview mirror every day before commuting. First, I sit upright in the driver's seat with my back firmly against the seat. Then, I gently rotate the mirror until the centerline of the rear window is perfectly aligned in my field of vision. This allows me to clearly see the entire road behind and the rooflines of following vehicles. If the rear window appears too high or too low in the mirror, it affects distance judgment and may lead to miscalculations. After adjustment, I coordinate with side mirrors to eliminate all blind spots, ensuring no死角 are missed during lane changes. Remember to complete this adjustment before starting the engine - never attempt to adjust while driving. For shared vehicles, recalibrate the mirrors every time you get in. Developing this habit significantly improves driving safety. In real-world driving, properly adjusted mirrors help me accurately gauge following vehicles' speed, preventing rear-end collisions and minor accidents.
Back when I was learning to drive, my instructor taught me the basic steps for adjusting the interior rearview mirror: First, sit firmly in the driver's seat, fasten the seatbelt, maintain a normal driving posture while looking straight ahead, then adjust the mirror until the lower edge of the rear window appears centered in the mirror surface, ensuring a complete view of the front end or lights of the vehicle behind. At first, I couldn't get it right, but later I realized the key was to keep my head still and only use peripheral vision to confirm whether the rear view was clear and unobstructed. During the novice stage, I would check it weekly to prevent the mirror from becoming loose or the angle shifting. After forming this habit, I could judge the distance of vehicles behind me more quickly while driving, especially on highways to avoid misjudgment. This simple adjustment not only boosted my confidence but also reduced driving risks caused by frequent head-turning.
