Learn how to park safely: You should follow the vehicle in front and park behind it in order. If you are the last vehicle, you should place a triangular warning sign 150 meters behind your car, turn on all the vehicle's lights, and ensure all passengers quickly move outside the guardrail. Highway traffic control under severe weather conditions is divided into the following three levels: 1. Level 3 Control: When heavy rain, snowstorms, or thick fog reduce visibility to between 100 and 200 meters, Level 3 control is implemented, involving partial road closures and traffic interruptions lasting less than 3 hours. 2. Level 2 Control: When heavy rain, snowstorms, or thick fog reduce visibility to between 50 and 100 meters, making it unsafe for vehicles to proceed, Level 2 control is implemented, involving regional road closures and traffic interruptions lasting 3 to 6 hours. 3. Level 1 Control: When heavy rain, snowstorms, or thick fog reduce visibility to less than 50 meters, or when road surfaces become icy, making it unsafe for vehicles to proceed, Level 1 control is implemented, involving full highway closures and traffic interruptions lasting more than 6 hours.
