I DROVE FROM THE STATE OF VIRGINIA, HEADING TO RENO, NV TO VISIT FAMILY. I WAS DRIVING A 2003 PONTIAC GRAND AM SE1 3.4L. THE CONDITIONS OF THE ROAD WERE WET, AS IT WAS RAINING. THE POSTED SPEED LIMIT WAS 75MPH - I WAS TRAVELLING AT 68MPH. I WAS INVOLVED IN A SINGLE CAR ACCIDENT, IN FORT BRIDGER, WYOMING. A SEMI-TRUCK CUT IN FRONT OF ME, IN THE LEFT LANE, FROM THE RIGHT LANE - SPLASHING ALOT OF WATER OVER MY VEHICLE. I HYDROPLANED AND MY CAR SPUN OUT OF CONTROL TO THE RIGHT. I HIT THE RIGHT SIDE OF THE ROAD GUARD RAIL WITH THE LEFT/FRONT OF THE VEHICLE, AND THEN THE CAR SLID ACROSS THE ROAD RAMMING THE LEFT SIDE OF THE ROAD GUARD RAIL, DEAD CENTER IN THE REAR END. I WAS WEARING MY SEAT BELT, BUT I WAS STILL SLAMMED AND JOLTED FORWARD AND SIDEWAYS. NEITHER OF MY DUAL FRONT AIR BAGS DEPLOYED. THE SPEED THAT WAS CALCULATED BY THE HIGHWAY PATROL AT THE TIME THAT I HIT THE GUARD RAIL WAS AT A MINIMUM OF 60-65MPH. THE AIR BAGS SHOULD HAVE DEPLOYED WITH EITHER IMPACT OF THE FRONT AND REAR, AT A MINIMUM SPEED OF 35MPH, AND THEY DID NOT. I HAVE PICTURES OF THE VEHICLE FROM THE INCIDENT.
