Moreover, the sleeper bus has only one door. In any emergency, the single door design is not convenient for passengers to escape effectively.
During the driving process, most passengers are asleep, sometimes unaware of the accident and unable to avoid it in time. The death rate of sleeper buses is relatively high every year, so many security risks require the state to ban the use of sleeper buses.
Document No.632 issued by the Ministry of Industry and Information Technology and the Ministry of Public Security on 20 12 stipulates that related enterprises shall not produce and sell sleeper buses, and sleeper buses shall not be registered for use. The service life of a sleeper bus is five years. Five years later, sleeper buses will be eliminated with history, and there will be no sleeper buses in future transportation.
Extended data:
In the 1980s, after the reform and opening up, the economic situation developed rapidly. At that time, a large number of individual traders urgently needed to transport small commodities from southeast to northwest. At the same time, a large number of migrant workers flow from the west to the east, and the travel characteristics of this group require low fares and more carry-on luggage.
At that time, it was hard to get a berth ticket for the train, expressway had just started construction, and high-speed long-distance passenger transport had not yet appeared. At the same time, buses with seats in expressway cannot meet the demand of long-distance passenger transport because of their slow speed, long running time and easy fatigue.
At the end of 1980s, at the request of Yunnan customers (Zhejiang customers) who run long-distance passenger transport, Yangzhou Bus Factory at that time began to trial-produce sleeper buses, which were listed in 1989.
