When driving in the countryside at night, old drivers often say, "Don't take the gray one, but park in the dark". What does that mean?

The village has developed greatly in recent years. Basically, cement roads have been built in every village, and street lamps have been installed in some places near towns, which has brought great convenience to farmers. So many peasant brothers, if it is easy to have money, will consider buying a car. It is much more convenient to travel by car in the village. However, the mountain road in Tunzi is not as spacious as the road in the city, and many experienced drivers will ask some old drivers for advice after buying a car. We often hear some old drivers say that when driving at night, we should keep in mind the principle of "walking in the gray, not walking in the white, stopping in the dark". What does this mean? Does this make sense?

Many people are a little overwhelmed when they hear this sentence for the first time. What are "gray" and "white"? Why do they stop when they see "black"? In fact, this sentence means that when driving at night, if the place where the headlights shine is gray, you can drive, because this "gray" is the color of the cement pavement under the light. And if it is a "red" place, then don't inherit it and drive forward. This is because the red place is the color reflected by the light shining on the water. In other words, there is water in the back. I don't know the depth, so I can't see well at night. If the water is deep, it is quite risky. If you are not familiar with the road conditions, don't inherit and advance!

Why "stop when it's dark"? This is because the road is gray, the lights are on, and the place outside the road is dark black. If there are some potholes in the back, it will be dark if the headlights shine on it. Therefore, when you see dark black, don't inherit and move forward, otherwise there will be no road behind, or there will be a big pit in the end, and the risk of inheritance and move forward is great.

"Don't walk away from the ash, stop in the dark" is the experience summary of the old driver, which is extremely reasonable and more applicable in the village. After all, in the village, there are no street lights in many sections, and there are many puddles in some places, so be careful when driving.
