ON, MARCH 7, 2010 AROUND 6:30PM, GOING ON THE HIGHWAY, WITHOUT ANY WARNING. THE 2009 TOYOTA COROLLA MODEL LE, WENT TOTALLY OUT OF CONTROL. I WAS ON THE FAR RIGHT LANE, HEADING FROM TOA BAJA TO MAYAGUEZ ON PR-22. REACHING ARECIBO, BY HIGHWAY MARK (KM 74.2) THE CAR STEERING WENT TOTALLY TO THE LEFT AND IN FRACTIONS OF SECONDS MY CAR INVADED THE LEFT LANE DOING A 180 DEGREE TURN, HAD CARS COMING MY WAY AND JUST WHEN I TOUGH THE OTHER CAR WAS GOING TO HIT ME. THE STEERING ON THE CAR WENT COMPLETELY THE OPPOSITE DIRECTION AND THE CAR ROLLED AGAIN AND I WAS GOING OVER THE GREEN AREA CRAZY FAST. NO CONTROL, SPINNING AGAIN OVER THE GRASS AREA ON THE MIDDLE OF THE HIGHWAY, HEADING RIGHT INTO THE OPPOSITE SIDE OF THE HIGHWAY, CARS COMING AT 65 MPH OR MORE. THEN THE CAR HIT A STREET SIGN THAT CHANGED THE CAR TRAJECTORY AND THEN CAME TO A STOP ON THE GREEN AREA ON THE MIDDLE OF THE HIGHWAY. THE CAR ENDED ALL COVERED ON GRASS, MUD AND IMPACTED BY THE STREET SIGN THAT POSSIBLY PREVENTED MY CAR FROM INVADING THE LANES ON THE OPPOSITE DIRECTION ON THE HIGHWAY AFTER THE TOYOTA COROLLA STEERED VIOLENTLY AND UNCONTROLLABLE SECONDS BEFORE. I HAVE TO SAY, THIS WAS AN EXTREME SITUATION THAT FOR WHO KNOWS REASON, ALL HAPPENED IN A SPLIT SECOND WITHOUT WARNING AND ALL THE VIOLENT EXTREME MOVEMENTS HAPPENED WITHOUT MY CAR IMPACTING OTHER CARS ON THE HIGHWAY, BUT CLEARLY I WAS VERY LUCKY. AT THE MOMENT OF THE INCIDENT, A PASSENGER WAS WITH ME IN THE CAR AND THEN CAN CONFIRM HAS WITNESS OF THE EXTREM
