What are the main causes of rear-end collisions between two vehicles?
2 Answers
The main reason for a rear-end collision between two vehicles is that the following vehicle fails to maintain a safe distance from the vehicle in front. Below are relevant details about safe distances: 1. Based on speed: When driving at 60km/h, the safe distance between vehicles should be more than 60 meters; when driving at 80km/h, the safe distance should be more than 80 meters. 2. According to road conditions: The safe distance between vehicles should also be determined based on specific road conditions. For example, in rainy weather, the safe distance should be increased. 3. Judging distance: While driving, you can use the rearview mirror to observe the safe distance between vehicles. If the following vehicle occupies one-fourth of the rearview mirror, it indicates a dangerous distance; the remaining three-fourths signifies a safe distance.
I've been driving for over ten years and have seen quite a few rear-end collisions. The main causes are often that the following car is too close, so when the car in front suddenly brakes hard, there's no time to react, resulting in a direct collision. Another factor is driver distraction, such as staring at a phone watching short videos and ignoring changes in road conditions, or driving while fatigued and dozing off, leading to delayed reactions due to lack of focus. In bad weather, wet or snowy roads increase braking distance, making rear-end collisions more likely. I usually make it a habit to calculate a safe distance, leaving a two-to-three-second buffer based on speed, especially being vigilant about the movements of the car ahead in traffic jams. Then there's the issue of speed—driving too fast on the highway and suddenly encountering a traffic jam means the car behind simply can't stop in time. These situations not only cause the hassle of car repairs but can also lead to chain-reaction accidents endangering lives. That's why it's crucial to stay focused and leave enough space when driving—prevention is key, to avoid trouble for yourself and others.
