MY VEHICLES AIRBAGS DID NOT DEPLOY I WAS HIT BY AN 18 WHEELER AT A HIGH RATE OF SPEED. THE VEHICLE HAD AT LEAST 2 REAR END HITS BY THIS 18 WHEELER ESTIMATED AT A SPEED IN EXCESS OF 25 MILES PER HOUR FASTER THAN MINE (I WAS GOING AT 70MPH NORTHBOUND ON US 75, NINE MILES SOUTH OF TULSA OKLAHOMA ON A SUNNY MONDAY AT 3PM). THE STREET WAS DRY. THE TRUCK INITIALLY HIT ME ON MY REAR AND ON MY LEFT REAR QUARTER. I WAS SPUN IN FRONT OF THE TRUCK AND HE HIT ME AGAIN ON THE REAR QUARTER AND THE BUMPER AND SPUN ME IN THE OPPOSITE DIRECTION AND THEN PUSHED INTO THE GUARDRAIL AT AN ESTIMATED 40+ MPH. THE AIRBAGS DID NOT DEPLOY FOR ANY OF THE THREE COLLISIONS (TWO IN THE REAR AND ONE IN THE FRONT).
