An Alcohol-Related
Crash
This is a slow-motion, split-second
reconstruction of what happens when a car, traveling 55mph, crashes into a
solid, immovable tree:
• One-Tenth of a Second
The front bumper and chrome ‘frosting’ of the grill work collapse. Slivers of
steel penetrate the tree to a depth of one and one-half inches or more.
• Two-Tenths of a Second
The hood crumbles as it rises, smashing into the windshield. Spinning rear
wheels leave the ground. The front fenders come into contact with the tree,
forcing the rear parts out over the front door. The heavy structural members of
the car begin to act as a brake on the terrific forward momentum of the
two-and-a-half ton car. But the drivers body continues to move forward at the
vehicle’s original speed (20 times normal force of gravity, his body weight is
3,200 pounds). His legs, ramrod straight, snap at the knee joints.
• Three-Tenths of a Second
The driver’s body is now off the seat, torso upright, broken knees pressing
against the dashboard. The plastic and steel frame of the steering wheel begins
to bend under the drivers grip. His head is now near the sun visor, his chest
above the steering column.
• Four-Tenths of a Second
The car’s front 24” have been demolished, but the rear end is still traveling at
an estimated speed of 35 mph. The body of the driver is still traveling at 55
mph. The rear end of the car, like a bucking horse, rises high enough to scrape
bark off the low branches.
• Five-Tenths of a Second
The driver’s fear-frozen hands bend the steering column into an almost vertical
position. The force of gravity impales him on the steering shaft. Jagged steel
punctures lung and intercostals arteries. Blood pours into his lungs.
• Six-Tenths of a Second
The driver’s feet are literally ripped from his tightly laced shoes. The brake
pedal shears off the floor boards. The chasis bends in the middle, shearing body
bolts. The driver’s head smashes into the windshield. The rear of the car begins
it’s downward fall, spinning wheels digging into the ground.
• Seven-Tenths of a Second
The entire body of the car is twisted out of shape. Hinges tear, doors springs
open. In one last convulsion, the seat rams forward, pinning the driver against
the steel of the steering shaft. The impact kills the driver instantly. |
