Is it necessary to honk the horn when overtaking?

[LeBryce]

When overtaking a vehicle, it is necessary to honk the horn to signal the vehicle ahead. Before overtaking, increase your speed, approach the left side of the vehicle being overtaken, reduce the following distance, turn on the left turn signal, and honk the horn (except in areas or sections where honking is prohibited; at night, use the high-low beam switch to signal the vehicle ahead). After confirming that the vehicle ahead has yielded or signaled to yield, slightly steer to the left, maintain a certain lateral distance from the vehicle being overtaken, and accelerate past it from the left. Precautions for overtaking: Before overtaking, check the overtaking lane for any following vehicles using the interior rearview mirror and the side mirrors; always be aware of whether the vehicle ahead has any intention to overtake—if so, abandon the idea of overtaking; do not overtake if the vehicle being overtaken signals a left turn or U-turn; also, do not overtake if there is a possibility of encountering oncoming traffic during the overtaking process.
