Why you must choose an off-road vehicle to travel along the Sichuan-Tibet Line

The reason why off-road vehicles are used for self-driving tours on the Sichuan-Tibet Line is that the off-road vehicles have high chassis and good passing performance. The Sichuan-Tibet Line is one of the most dangerous lines in my country. The line has a total length of 2,000 kilometers. It passes through many places with rugged roads, high slopes and steep roads, and some sections are accompanied by natural disasters such as heavy rains, mudslides, and landslides. The chassis of ordinary family cars is too low and it is easy to break down on the road, so self-driving tours on the Sichuan-Tibet Line require an off-road vehicle with a high chassis.

When the Sichuan-Tibet Highway was built, it was restricted by historical conditions, economic and technical levels and other factors. The construction time of the highway was short, the engineering level was low, and the construction was rough. It was basically an emergency highway. In addition, the hydrology and meteorology along the route , The terrain and geological conditions are very complex, and various mountain disasters occur frequently, so traffic jams and disconnections often occur.

The Sichuan-Tibet Highway passes through 14 mountains including Erlang Mountain, Zheduo Mountain, Queer Mountain, and Sejila Mountain in the entire Hengduan Mountains; it crosses the Minjiang River, Dadu River, Jinsha River, Nujiang River, Lhasa River, etc. Many rivers; crossing 8 major fault zones including Longmen Mountain, Qingni Cave, Lancang River, and Tongmai.
