Not wearing a seat belt while driving will greatly increase the risk of serious injury or death, and there is no way to truly replace the role of seat belts. According to global traffic safety research, the correct use of seat belts can reduce the death rate in accidents by 40%-50%. The following are a few points that must be emphasized from a safety perspective： **1. No alternative: safety designs such as airbags and body structures are premised on “passengers fasten their seat belts”. ** -The impact force of the airbag when it is deployed is as high as 300km/h. Failure to wear a seat belt may cause the head to directly hit the airbag, causing fatal injuries such as cervical spine fractures. -Experimental data show that even in a low-speed collision at 40km/h, the probability of an occupant who is not wearing a seat belt hitting the windshield with his head is more than 90%. **2. Analysis of common misunderstandings：** -*"Safety belts are not required for short-distance driving”*: 70% of fatal accidents occur within 15 kilometers of home. -*"No need to fasten the rear seat"*: Rear passengers who are not wearing seat belts will hit the front seats like cannonballs in a collision, resulting in a 3-fold increase in the mortality rate of the front-row personnel. **3. Law and Biomechanical Reality：** -More than 160 countries around the world have legislated to enforce the use of seat belts, and violators may face high fines or even imprisonment. -The inertial force of the human body in a 50km/h collision is equivalent to falling from an altitude of 10 meters, and it cannot be resisted by the strength of the arm alone. **The only scientific advice：** -The first action after getting in the car is always to fasten your seat belt (including the rear seat). -If it cannot be used for medical reasons, you need to obtain a doctor's certificate and use a specially modified safety device (such as pelvic pads, etc.). - Children must use a compatible safety seat. The seat belt can cause fatal damage to their internal organs. Please remember: all traffic safety studies have proved that **"Survival strategy when not wearing a seat belt” itself is a false proposition**. There is only one choice to protect life: the correct use of seat belts.
