Turn Off the Engine First or Unbuckle the Seat Belt First?

[VonDaniela]

Turn off the engine before unbuckling the seat belt. Here is an introduction to seat belt-related content: 1. Function: The seat belt functions to restrain movement and provide cushioning, absorbing impact energy and mitigating inertial forces to prevent or reduce the severity of injuries to drivers and passengers. Car accident investigations show that wearing a seat belt can reduce fatalities by 57% in frontal collisions, 44% in side collisions, and 80% in rollovers. 2. Principle: When a strong frontal collision occurs, the driver and passengers' bodies move forward rapidly due to inertia. At this point, the seat belt will exert force to "hold back" the bodies, absorbing part of the impact energy while the airbags inflate and fully deploy.
