The truck horn is an important acoustic signaling device for ensuring safe driving, with the main function of conveying warning and signaling information through a piercing honking sound. Its high-pitched and loud tone far surpasses that of ordinary car horns, enabling it to quickly catch the attention of other vehicles and pedestrians in complex road conditions, making it particularly suitable for scenarios such as overtaking on highways, passing vehicles at curves, and adverse weather conditions, thereby effectively reducing the risk of collisions.
Moreover, it can convey specific meanings through different beeping rhythms, such as a short beep indicating a request to overtake, a long beep warning of danger, and a sequence of short beeps reminding those around to be cautious. Some models are also equipped with multi-frequency whistle designs to adapt to various environments like urban and mountainous areas, thereby meeting regulatory requirements while enhancing communication efficiency during driving.
