ACTUALLY HAD TWO VERY SIMILAR SITUATIONS ALTHOUGH ONE WAS ON ICE AND THE OTHER DUE TO HYDROPLANING. WAS TRAVELING ON INTERSTATE IN BOTH INSTANCES AT BELOW SPEED LIMIT AND CAR SEEMED TO FLOAT OFF TO THE RIGHT AND THEN GO INTO UNCONTROLLABLE SPINS BOTH INSTANCES WERE NEARLY IDENTICAL WITH THE LAST ONE RESULTING IN CAR CAREENING INTO DITCH AND STRIKING GUARDRAIL I DO NOT FEEL I WAS TRAVELING AT HIGH RATE OF SPEED IN EITHER INSTANCE BUT AM NOT FRIGHTENED TO RIDE IN VEHICLE DURING ANY KIND OF INCLEMENT WEATHER.
