The height limit device can be used in different restricted areas. When the driver fails to observe the restricted sign ahead due to special reasons, the vehicle will collide with the height limit pole and will first collide with the height limit pole. The rising plate on the height limit pole will first contact the vehicle. After being squeezed, the rising plate will compress the first spring for buffering and reduce the risk of collision. Since the height limit pole is circular in shape, the height limit pole will rotate to slow down the vehicle after the vehicle collides. When the vehicle speed is too high, the height limit pole will be squeezed upward to lift the height limit pole. Due to the action of the adjusting component, the height limit pole will rise, and the action of the limit block will block the height limit pole, so that the height limit pole cannot fall, thereby reducing the degree of danger caused by the fall to the driver.
