What Happens When Unbuckled Bodies Collide in a Crash

In this Public Information Film, you learn how unbuckled bodies can collide in a crash, increasing risks of injuries and fatalities. Traveling at 30-mph, an adult passenger riding in the back seat without his seat belt fastened is thrown forward with a force of 3½ tons, the weight of an elephant charging straight through the driver.

There are three collisions in every crash, according to Emergency Medical Paramedic:

  • Vehicle collision: The vehicle begins stopping as it collides with another object
  • Human collision: The occupant continues to move toward the point of impact at the same speed even though the vehicle begins to stop once impact occurs
  • Internal collision: The occupant’s internal organs move toward the point of impact and hit other organs, bones and the skull
