I was driving down a main road near the Piedmont triad international airport having a casual conversation with my passenger. I went to make a left turn into a Sheetz gas station when all of a sudden the passenger airbag deployed, without warning or wreck. The passenger hand flew up into windshield and cracked the windshield. The Immediately after the passenger airbag deployed without warning the airbag in the steering wheel deployed and my arm was slung into the driver side window and went completely through.
