The new version of "Safety Technical Conditions for Motor Vehicles" was officially implemented on September 1. It requires that special school buses and sleeper buses must be equipped with an on- and off-camera video surveillance system. An emergency hammer must be provided in the vicinity of the vehicle emergency window. Compared with the old version of the "Safety Technical Conditions for Motor Vehicle Operation" in 2004, the new standard proposes that all school buses, road buses and tourist buses should be equipped with information on the driving status of the vehicle, such as the speed, time and mileage of the vehicle. Driving recorders, special school buses and sleeper buses should also be equipped with on- and off-camera video surveillance systems. In the safety guard project, the new conditions require the vehicle emergency window to be easily and quickly opened from the inside and outside of the vehicle; or to indicate a location that is easily crushed on the tempered glass and provide an emergency in the vicinity of each emergency window. The hammer is used to easily break down the window glass, and the emergency hammer should be able to alarm by sound signal.
