What does it mean to "see the car at the rear of the car and overtake the car to see the front of the car"

It is undeniable that although there are more and more people buying cars today, but there are not many people who really understand cars, many car owners are driving according to the experience taught by the old drivers around them, but because everyone's habits are different, the models are different, if it is not their own personal experience, there will be some misunderstandings.

For example, when driving, there are two situations of driving and overtaking, and many novice drivers are not yet proficient in handling these two situations, and even make wrong judgments because of other people's statements. Then here Xiaobian can teach everyone to remember a sentence, that is, "will look at the rear of the car, overtaking to see the front of the car".

First of all, let's see why we have to look at the rear of the car when we encounter it? Many people expressed doubts, the car is coming at the front, isn't it more troublesome to see the rear of the car? But in fact, this sentence is about the situation after the car, if you are borrowing the other party's lane, then you can judge whether the other party's car has driven away through the rearview mirror after the car, so as to decide whether you want to change lanes.

And if you can see the rearview mirror of the other party's car, it means that you have driven far away and can change lanes. But if you can only see the body or the front of the car, it means that the car is not yet complete, then if you change lanes at this time, it is very dangerous.
