Air Bag Not Deploy problems of the 2005 Dodge Stratus

I was driving down dundee rd in illinois and it was rain/snow mix and as I was coming to an intersection the car failed to stop and when the impact happend the airbags failed to deploy and the car was in motion on a city street.

I was driving my 2005 Dodge Stratus sxt along on a gravel road on oct 12 2008 and had a deer run out in front of me. When I swerved to avoid the deer my left front tire blew and caused my car to end up in a ditch. I was traveling approx 35 to 40 mph, neither air bag deployed and the entire front end of my car was destroyed to include the front bumper cover, both front fenders, the hood. The insurance company totaled the vehicle due to $5900 worth of damage. Now I would like to know why the air bags never deployed.
