WHILE DRIVING SOUTH IN THE FAST LANE, THE FRONT LEFT TIRE BLEW OUT (NO APPARENT REASON). THE DRIVER STRUGGLED TO MAINTAIN CONTROL OF THE SUV BUT HIT THE GUARD RAIL WITH THE LEFT FRONT BUMPER TRAVELING APPROXIMATELY 75 MPH. THE BACK LEFT TIRE THEN BLEW AND THE DRIVER HIT THE GUARD RAIL AGAIN, AT WHICH POINT THE A-FRAME AND FRONT AXLE WERE DESTROYED, ELIMINATING STEERING AND BRAKING FUNCTIONS. THE SUV CAREENED ON THE TWO LEFT TIRES, THEN SEVERAL MOMENTS LATER THE CAR FELL BACK DOWN TO ALL FOUR WHEELS, AND THE VEHICLE SLID ACROSS FIVE LANES OF TRAFFIC TO A STOP IN THE FAR RIGHT LANE. AT NO POINT IN TIME DID THE AIRBAGS DEPLOY. *TR
