How to check whether the high speed is off?

Inquiries about whether the expressway is closed can be made through the internet, telephone, listening to the radio and paying attention to official news.

1. Online inquiry: Visit China Expressway Network () or some navigation software, such as Gaode Map and Baidu Map, which usually provide real-time information on expressway conditions.

2. Telephone inquiry: Call the expressway service to inquire about the expressway traffic according to the voice prompt or communicate with the customer service staff. The telephone number may be different in different regions, so you can search the telephone number of expressway service in the corresponding region on the Internet.

3. Listen to the radio: Listening to the local traffic radio usually broadcasts the traffic situation of the expressway in time.

4. Pay attention to official news: Pay attention to social media accounts such as Weibo and WeChat official accounts. Usually, they will announce the traffic situation of the expressway in time.

Causes of high-speed shutdown

1. Bad weather: Extreme weather such as snowstorm, hail and rainstorm will lead to slippery roads, low visibility and easy loss of control of vehicles, so the expressway will be closed to ensure driving safety.

2. Poor road conditions: If there is snow or ice on the road surface and it cannot be removed immediately, the expressway must be closed to ensure driving safety.

3. Traffic control: In case of traffic accidents or other emergencies, the high-speed traffic police department will implement traffic control and temporarily close the expressway.

4. Fog influence: Fog has local characteristics. Most foggy weather on the expressway is a mass of fog. In many cases, the visibility of the toll station has improved, but the visibility of the main highway has not met the traffic requirements, or the visibility of the entrance of the toll station has improved. There is still fog at the next toll station and the next road section, which still does not meet the visibility requirements. It is impossible to see the weather from one point to another. Only when the surrounding sections reach the traffic conditions will the expressway be opened.
