I entered my car and put the key in the ignition when I started the car the drivers air bag activated. I was back in my seat so it never touched me. . . . . Updated 07/23/14.
I was traveling south on highway 385 when a deer flew out in front of me. We hit head on destroying the whole front end of my car. I would like to know why the air bags did not go off if that deer would have flown up on the hood and came through the windshield it could have killed me. The air bag could have saved my life. Why did it not deploy.
