What's the point of honking the horn?

On the surface, honking the horn is a traffic signal, but it has many potential meanings in real life.

1, "DuDu": Two cars meet when driving in opposite directions.

This "beep" is soft and short, which sounds comfortable and won't make people feel disgusted. It is often used to say hello between drivers or between drivers and pedestrians, or as a polite behavior when two cars get on the wrong bus.

2. "DuDu" twice: when overtaking, give three points of courtesy in return. Generally speaking, when overtaking, the car goes first, and the fast car goes first. You can reply to each other with a short beep.

3. "DuDu" three sounds: remind pedestrians or non-motor vehicles to pay attention. In normal driving, in order to remind pedestrians and non-motor vehicles in front, they will use the short and rhythmic language "Didi Di" to let them pass by themselves to avoid traffic accidents.

There is a traffic jam at the intersection, and you keep honking your horn.

At some congested intersections, especially when pedestrians, bicycles and motor vehicles are mixed, it is likely that there will be a green light all the way. However, due to congestion, many drivers habitually use horns to warn the vehicles in front and honk their horns for a long time.

If this happens, we advise drivers to observe the situation first. If the road is really clear and the vehicle in front is not started, you can choose to use the light to prompt, but if it still doesn't work, you can use the horn to prompt the other party once.
