In a motor vehicle collision, what are the three collisions that occur?

In a crash, injuries arise from a sequence known as the three collisions: first, the vehicle hits an external obstacle; second, the occupant collides with the interior of the vehicle; third, the occupant’s internal organs collide with solid structures inside the body due to the sudden deceleration. The option that matches this sequence lists the vehicle colliding with an obstacle, the occupant colliding with the vehicle, and the occupant’s internal organs colliding with internal body structures. The other options involve airbags, seats, clothing, dashboards, or tires, which are not part of this standard three-collision sequence. Understanding this helps explain why restraints and airbags reduce injury by limiting the second and third collisions.
