Modern helmets have different structures and styles due to different requirements for various activities. For example, helmets used by people in traffic are used to prevent head injuries caused by collisions and falls during traffic. Even in a mode of transportation at lower speeds such as cycling, there are also safety issues that cannot be ignored, so the role of wearing a helmet is very important.
