Snow and ice have appeared on roads in various places, making the roads slippery and easily causing traffic accidents. Traffic police remind drivers to drive carefully, reduce speed, and control the distance between the front and rear cars.
If you encounter an emergency, you must "drive the car onto the hard shoulder, move people out of the guardrail, and stay away from the parking spot" and dial "12122" to call the police for help. Since the Spring Festival travel rush, the average daily traffic flow at the expressway has increased by more than 20% compared with usual times.
