Whether it is a flat place or a bumpy place, their highways and roads are always twists and turns.

So many people have doubts that the construction of bending roads between cities is to avoid buildings and some parks, but in the wild, why still waste a lot of money to build a winding road? Today we will take you to understand why the curved road is built.

Anyone who has learned geometry knows such common sense, that is, the distance between the two points is the shortest.

The highway built according to this principle can not only save a lot of costs but also shorten driving time and improve people's travel efficiency.

But this simple truth is almost no one executed. Because of the highway and wild roads are straight, many potential dangers will be caused.

The speed of cars driving on highways is basically stable in one range. In this case, the changes in the noise and vibration frequency in the car are relatively small, and the stimulation of the driver's sensory sense will be very small, so the driver will easily enter the fatigue driving mode.

Building the highway into a curved appearance can also greatly reduce the chance of a car accident because the emergence of the curve allows the driver to concentrate better and prevent the owner from driving a car accident due to fatigue driving.

In addition, the construction of highways is closely related to the terrain. Because highways are generally built in remote mountainous areas, they need to bypass or cross the mountain.

However, it is still very difficult to make the highway through the mountain, so it is usually chosen to take a detour. This purpose is to avoid the mountains and reduce their impact on the mountain. So many curves will appear.

Many people are careless when driving, so it is easy to speed, fatigue driving, and other conditions, and may even cause accidents. It's even more dangerous on the highway. To be on the safe side, you must pay attention to the following points when driving on the highway.

1. Don't speed. There will be speed limits on the roads, but there are still many drivers who risk themselves and others by speeding. This can easily lead to rollover, rear-end collision, and other situations.

And driving too fast gives you less time to react. Research shows that at 100 kilometers per hour, a car in an accident is equivalent to falling from a 10-story building. The risk is very high.

2. Don't drive distracted. Because of the high speed on the motorway, it is important to concentrate on driving. If the driver is slightly distracted, a momentary lapse of concentration can lead to a serious traffic accident.

So on the road, don't get distracted. Driving while talking on the phone, for example, is even more dangerous!

3, when driving on the highway, do not stop at will, this behavior will affect the safety of you and others. Even if you want to stop, park in the emergency lane.
