On March 2, 2022, at about 0/5 o'clock in Kloc-0, the police and auxiliary police of the 17th Brigade of the Traffic Management Bureau of Ningxia Public Security Department were on duty in the sub-control center of the brigade. Through video patrol, it was found that a light ordinary truck turned on the vehicle safety warning light and stopped in the emergency lane, and there was no triangular warning sign, which was a big safety hazard.

The personnel on duty in the sub-control center of the brigade immediately inquired about the driver's contact information through the vehicle license plate, contacted the driver by telephone, and informed the driver to place a triangle warning sign at the rear of the vehicle150m, and evacuated the personnel outside the guardrail. Another policeman informed the driver by broadcasting to remind the passing drivers to slow down. Later, the brigade quickly sent police to drive the vehicle to the scene and learned that the destination of the vehicle was Suining. When the Wuma Expressway has been driving for 220 kilometers from south to north, the vehicle broke down and could not move. I didn't contact the high-speed rescue because I was afraid of towing. The attendant of the sub-control center told the driver that Ningxia Expressway rescue was free, and then helped him contact the expressway rescue team. The police also pushed the vehicle to a safe place, waiting for the rescue team to safely drag the vehicle away from the high speed.
