I was driving on a two lane highway, fm 185. I was driving northeast while the other driver was somewhat stopped heading west, trying to turn south onto cattle drive. The other driver was stopped at an intersection awaiting to turn left. The other driver turned left in front of me as I was headed straight. The initial impact was driver's front side and then down the drivers side door. We hit, and then my vehicle did a 180 degree turn which turned my vehichle around facing my intial path of direction. My airbags did not deploy. I had curtain side airbags, driver, and passenger air bags as well. The airbags of the car causing the accident did deploy.
