How to Judge the Distance of the Rear Car When Changing Lanes?
1 Answers
To accurately judge the distance, first observe the distance of the rear car and adjust the rearview mirror properly. When the rear car fills the entire rearview mirror, the distance between the two cars is approximately 3 meters. When the rear car fills the left rearview mirror, the actual distance is about 1 meter. When the rear car fills the right rearview mirror, the distance between the two cars is very close, and these situations are not safe distances. Changing lanes under such conditions is dangerous. More details are as follows: 1. When the rear car fills half of the right rearview mirror: The distance between the two cars should be about 9 meters. For experienced drivers, this distance is relatively safe, but novice drivers may find it difficult to master and need to be extra cautious. When the rear car fills 1/3 of the left rearview mirror, the distance between the two cars should be about 10 meters, and from the right side, it should be about 12 meters. Generally, such distances can be considered safe, but at high speeds, if the car in front brakes suddenly or overtakes, it can still be dangerous. 2. Observing the distance of the car in front: If you can see the upper edge of the rear bumper of the car in front, the distance is about 1 meter, and you should be cautious about sudden braking by the car in front, as it may lead to a rear-end collision. If you can see the lower edge of the rear bumper, the distance is about 2 meters, which is ideal in traffic jams. If you can see the lower edge of the rear wheel hub of the car in front, the distance is about 3 meters, but in heavy traffic, this distance may allow other cars to cut in. 3. Maintaining a good field of vision while driving: This is one of the conditions for safe driving. Therefore, before driving, adjust your seat position and rearview mirrors properly. In crowded areas, maintain a safe distance from the car in front, but also avoid leaving too much space, which may invite other cars to cut in. Especially on roads with many electric vehicles, which are unpredictable, extra caution is needed. When changing lanes, leave enough space, ideally with the rear car occupying only 1/3 of your rearview mirror, for safer maneuvering. Develop correct driving habits and avoid speeding.
