Under what circumstances will roads be closed in expressway? Specific point

Closed in bad weather (rain, snow, fog), major traffic accidents, traffic control, etc. Most roads are closed because the visibility is less than 100 meters due to heavy fog, and it will only be closed on holidays. At this time, the traffic volume is large and traffic accidents cause congestion.

There are two forms of expressway closure. One is that the toll station is closed, that is, all entrances are closed and vehicles are not allowed to enter. But cars on the main line can still leave expressway, and they are allowed to leave. The other is the main line closure, that is, the main line in expressway is closed in one direction, and vehicles are prohibited from moving forward. In this case, we should obey the arrangement of traffic police and road administration and leave the main line of expressway under the guidance.

In these cases, you can only park in the emergency lane; in other cases, you are not allowed to park in the emergency lane of expressway.

Some food will be prepared before going out, which can be eaten on the way. But it also produces a lot of garbage, and car owners with bad moral conduct will throw these garbage out of the window conveniently. This action is not only wrong, but also fatal if the circumstances are serious. Littering in expressway not only causes environmental pollution, but also may lead to traffic accidents.
