How to Determine the Position of the Rear of the Car Through the Rearview Mirror?
2 Answers
The method to determine the position of the rear of the car through the rearview mirror is: 1. When reversing, if a car behind occupies the entire rearview mirror, the distance is approximately 3 meters; 2. If the car behind occupies two-thirds of the rearview mirror, the distance is about 5 meters; 3. If the car behind occupies half of the rearview mirror, the distance is about 9 meters; 4. If the car behind occupies one-third of the rearview mirror, the distance is about 12 meters. The method to adjust the rearview mirror is: 1. For the left exterior rearview mirror, adjust the horizon image in the mirror to the center, and adjust the image of the left side of the car to occupy one-fourth of the right side of the mirror; 2. For the right exterior rearview mirror, adjust the horizon image in the mirror to two-thirds of the mirror's height, and adjust the image of the right side of the car to occupy one-fourth of the left side of the mirror.
I've been driving for twenty years and often teach friends how to judge the rear position of the car using rearview mirrors, which is very practical. The first step is to adjust the mirror angles properly. The interior rearview mirror should cover the entire rear view, while the side mirrors should just show a bit of the car's body. When reversing, I observe the size of obstacles in the interior rearview mirror: if the entire bumper of another car is visible, the distance is about two meters; if the wheels start to appear, it's around half a meter left. The side mirrors are also crucial—I check the proportion of the car body in the mirror. If it's less than one-third, it means the side and rear are safe. Practice parallel parking often, like in supermarket parking spaces, and you'll gradually learn to read distance changes. Be extra careful when mirrors are blurry in rainy weather—clean them before maneuvering. This habit has helped me avoid scratches and even improved my reversing speed. Remember, don’t rely solely on intuition; mirrors are the reliable tool. Safe driving comes from attention to detail.
