Is it not allowed to honk the horn at all in no-honking zones?

[DeKaden]

In no-honking zones, you are not allowed to honk the horn at all, otherwise you will be fined. When you need to alert others, you can alternately use the high and low beams. This is commonly referred to as "flashing the lights," which is also a method encouraged by traffic police for everyone to use. Function of the horn: The horn is the audio signaling device of a car. During driving, the driver can emit necessary audio signals as needed and in accordance with regulations to warn pedestrians and alert other vehicles, ensuring traffic safety. It is also used to urge movement and convey signals. How the horn works: A car's electric horn produces sound through the vibration of a metal diaphragm. When the horn button is pressed, current flows through the contacts to the coil, generating a magnetic force that pulls down the armature, forcing the diaphragm to move. The movement of the armature causes the contacts to open, interrupting the current and making the coil's magnetic force disappear. The diaphragm, along with the armature, returns to its original position due to its own elasticity and the spring plate, closing the contacts again and reconnecting the circuit. Current then flows through the contacts to the coil, generating magnetic force and repeating the above process. This cycle repeats continuously, causing the diaphragm to vibrate and produce sound.
