With its solid body, it guards the smooth flow of roads and escorts the development of cities. The existence of height limit poles is of great significance. They are specially used to intercept those super-high and super-large vehicles to prevent them from putting pressure on busy roads or vulnerable roads, and even causing serious traffic safety hazards. For example, preventing vehicles from "over-driving" serves to warn drivers that there are obstacles ahead and protect structures such as bridges and culverts. The setting of height limit poles is based on specific circumstances and imposes certain restrictions on the types and loads of passing vehicles, thereby maintaining traffic order and protecting the safety of roads and bridges. With the development of society, height limit poles are used when large vehicles need to pass through roads or bridges.
