Drivers who have driven a car know that when learning a driver's license, the coach will clearly tell every student who is studying that if he wants to pass the driver's license test, he must walk around the car every time before getting on the bus. In fact, many coaches have asked for this action, but they have not explained the meaning of this action in detail, which has led many drivers to slowly forget this action while driving, and many drivers regret it for life because of carelessness. Although driving is convenient for you, me and him, because of the power and self-weight, if you hit something or someone, it will bring great harm. So be sure to control the speed and direction when driving.

1. Why do you need to take a detour before driving?

It is of great significance to the country that students are required to walk around the car body when they get on the bus in the driving license examination subject III. Because there are many blind spots in the car, these blind spots will cause people to sit in the driver's seat and can't see whether there are objects or people in some parts. If you walk around the car for a week, you can clearly understand the surrounding environment of the car and be aware of it when driving, so as to avoid problems caused by straying into the blind area.

Second, what are the car blind spots?

There are many car blind spots, which are divided into visual blind spots and artificial blind spots. Visual blind zone refers to the front blind zone, rear blind zone, rearview mirror blind zone and A-pillar B-pillar blind zone when sitting in the driver's seat. If there are too short objects or people in these four blind spots, the driver will not notice them at all. When driving, if there are some artificial blind spots due to sitting posture and other reasons, a deep solar film is attached to the rearview mirror or something is hung on the window, the driver will not see it.

As can be seen from the above points, there are many blind spots in the car, and there are large and small blind spots around the car body. In addition, some people like to decorate the car, which will lead to blind spots in the car. Therefore, when driving, we must do a good job in blind areas to avoid accidents.
