What is the no parking sign?

The red circle with a blue background and a red cross means that parking is prohibited on the whole line, which means that temporary parking is not acceptable. There is only a blue background or a red diagonal line in the red circle, which allows temporary parking, but it is forbidden to park for a long time.

There are two kinds of no parking. One is a no parking sign, which means you must never stop, no matter how long it takes. There is also a sign prohibiting long-term parking, which means that temporary parking is allowed, but long-term parking is not allowed.

Extended information:

There is a solid yellow line on the pavement. It must be noted that this is a no-parking line on the ground. If you park in this place, you will be fined.

there is a yellow dotted line on the road tooth, that is, there is a marking line consisting of a yellow line and a black line on the road tooth. This kind of marking is a temporary parking marking. There is nothing wrong with short-term and temporary parking, but the parking time should not be too long. If you park for a long time and there is a traffic police next to you, you will usually be persuaded to leave, and you will be punished when the persuasion is invalid.
