In 1956, the famous competitor William Snell died tragically in a motorcycle race held in California, USA. Later, the relevant scientific research institutions in the United States listed the design of safety helmets as a key research project.

After repeated experiments, experts have proved that the head is hit violently when an accident occurs, and the helmet can effectively protect the head.

Because the helmet is smooth and hemispherical, it can disperse the impact force and absorb the impact force, while the deformation or cracks of the helmet and the cushion play a buffer role and can also absorb part of the energy.

It is estimated that a person's head can generally withstand an impact force of 450 kg. These functions of the safety helmet can reduce the impact force by about 1850kg, so the actual impact force on the head is only about 400kg. In addition, the bright and eye-catching color of the safety helmet can also attract the attention of the driver of the other side when meeting or overtaking. This shows how important the role of safety helmets is!

Therefore, all countries in the world have stipulated that helmets must be worn when riding motorcycles, and some countries even have to wear helmets when riding bicycles. China's Road Traffic Safety Law also clearly stipulates that helmets must be worn when driving and riding motorcycles.

Some people do not understand the role of safety helmets, and blindly believe that the purpose of public security traffic police's inspection and correction of not wearing helmets is to punish. However, the public security and traffic police do not find such people "trouble", and they will have more "trouble" after the accident!
