Vehicles under the collapsed mountain in Xunyang, Shaanxi Province escaped fortunately. What are the possible safety hazards in mountain roads?

There are four major safety hazards in mountain roads: debris flow, landslide, falling rocks on the top of the mountain and driving in curves.

Debris flow is the biggest safety hazard of mountain roads, especially after the rainy season, continuous rainfall will lead to loose soil and increase water quantity on the mountain. If there is a river on the mountain, the water level will appear when it rises to a certain extent, and a large amount of soil on the mountain will rush down the mountain when the dam breaks. Vehicles on mountain roads will be washed away or buried after encountering mudslides, which is easy to have extremely serious consequences.

There may also be hidden dangers of landslides on mountain roads, because the mountain structure is complex, and it is easy to loosen the car body and collapse when encountering geological changes, mudslides and heavy rainfall. At this time, the vehicles driving on the mountain road are likely to be buried by landslides, causing extremely serious consequences. Therefore, when you find that the local geological conditions are complicated or there is miraculous rainfall, you must take a detour and try not to drive on the mountain roads in these dangerous periods.

Rockfall at the top of the mountain is also a safety hazard of mountain roads. The stones on the top of the mountain will loosen after being weathered by the sun and the wind and rain. When they are affected by vibration or external force, they may fall down the mountain and roll directly down the mountain. In the process of rolling down, they will pose a certain threat to the vehicles driving on the mountain road. If they directly hit a moving vehicle, it will have particularly serious consequences, which may crash the vehicle and kill people.

Driving in curved roads is also a safety hazard of mountain roads, and traffic accidents often occur when driving on such roads. Drivers should correctly control the steering wheel when driving on a mountain bend, slow down and sound the horn as soon as possible when turning, and drive to the right to get ready for the oncoming car. When driving up and down mountain roads, you should use appropriate gears to keep the vehicle fully powered, avoid neutral sliding when driving downhill, make full use of the resistance of the engine, and don't brake with your feet for a long time.
