OUR VIEW With so many people taking to the roads for summer vacation, remember to buckle your seatbelts when hitting the road. Here's what the National Highway Safety Administration has to say about how a crash works. Maybe those of you who don't buckle up will think about this the next time you get in your car or truck. The Car's Collision The first collision is known as the car's collision, which causes the car to buckle and bend as it hits something and comes to an abrupt stop. This occurs in approximately one-tenth of a second. The crushing of the front end absorbs some of the force of the crash and cushions the rest of the car. As a result, the passenger compartment comes to a more gradual stop than the front of the car. The Human Collision The second collision occurs as the car's occupants hit some part of the vehicle. At the moment of impact, unbelted occupants are still travelling at the vehicle's original speed. Just after the vehicle comes to a complete stop, these unbelted occupants will slam into the steering wheel, the windshield, or some other part of the vehicle interior. This is the human collision. Another form of human collision is the personto person impact. Many serious injuries are caused by unbelted occupants colliding with each other. In a crash, occupants tend to move toward the point of impact, not away from it. People in the front seat are often struck by unbelted rearseat passengers who have become high-speed projectiles.
The Internal Collision Even after the occupant's body comes to a complete stop, the internal organs are still moving forward. Suddenly, these organs hit other organs or the skeletal system. This third collision is the internal collision and often causes serious or fatal injuries.
