Why is there no reverse image of the big truck?

Cars have been talking about safety, but cars will have many blind spots, especially big trucks. Many people don't know how dangerous it is to engage in an industry. Although the salary is high, the same car is very risky. Accidents are generally not a small problem. If the boss is himself, the car he drives can't cover the maintenance fee, and he usually drives with the boss himself.

The picture comes from the internet.

There are many blind spots in the truck, and there are basically not many places except to see the front clearly. While his son was playing outside, a father was backing the car. Fortunately, the child is not tall enough, and the father didn't know until he saw how his son appeared in front of him. Otherwise, the consequences will be unimaginable.

As the pillar of the family, once something goes wrong, it is a big problem, so it is safe for everyone to go out and there are many blind spots.
