    CONSEQUENCES OF A COLLISION WITH A HIGHER UNDERRIDE GUARD

    THIS PHOTO SHOWS THE TERRIBLE CONSEQUENCES OF A COLLISION WITH AN UNDERRIDE GUARD PLACED ABOVE THE FRONTAL BUMPER OF A GM BLAZER STATION WAGON.

    AS IS CLEAR, THE BLAZER BUMPER WAS NOT DAMAGED BY THE COLLISION! BUT THE TRUCK GUARD PUSHED THE MOTOR BLOCK BACKWARDS, CAUSING CONSIDERABLE DEFORMATION. AS A CONSEQUENCE, THE TRUCK CARGO TRAY HIT THE WINDSHIELD OF THE STATION WAGON, CAUSING HEAD INJURIES TO THE DRIVER.

    THE STEERING WHEEL, PUSHED BACK BY THE COLUMN, BROKE THE DRIVERS LEG. FORTUNATELY THERE WAS NO OTHER OCCUPANT ON THE FRONT SEAT. OTHERWISE INJURIES TO BOTH OF HIS LEGS WOULD HAVE BEEN SEVERE. THE WINDSHIELD WAS BROKEN BY THE CARGO TRAY, AND PASSENGER COMPARTMENT INTRUSION WAS LIMITED BY INSUFFICIENT COLLISION SPEED AND/OR BY SOME VALUE OF GUARD STRENGTH. CONCLUSION: TYPICAL CASE OF HALF SAFETY.
