Experienced doctors know that many patients do not die from the first direct impact, but from the secondary inertial acceleration impact injury that follows, which is especially common and severe in traffic accident patients.
To prevent such secondary impact injuries, traffic regulations repeatedly emphasize that both drivers and passengers must wear seat belts. Seat belts can effectively limit the force of inertia. In this traffic accident, Xiao Yu's situation is clearly a result of not wearing a seat belt.
Without wearing a seat belt, this child's body was thrust forward violently in the first impact, hitting his forehead, followed by his head being thrown back due to inertia, the second impact being even faster, hitting precisely the critical area for life.
