Will highways be closed during heavy rainstorms?

[MacOlive]

Whether highways will be closed during heavy rainstorms depends on the situation. Under severe weather conditions, highway traffic control is divided into three levels: 1. When heavy rain, snowstorms, or dense fog occur on highways with visibility between 100 and 200 meters, Level 3 control is implemented (partial road closures, traffic interruptions for less than 3 hours). 2. When heavy rain, snowstorms, or dense fog occur on highways with visibility between 50 and 100 meters, making it unsafe for vehicles to pass, Level 2 control is implemented (regional road closures, traffic interruptions for 3 to 6 hours). 3. When heavy rain, snowstorms, or dense fog occur on highways with visibility below 50 meters, or when road surfaces become icy, making it unsafe for vehicles to pass, Level 1 control is implemented (full road closures, traffic interruptions for more than 6 hours).
