I was driving down the road in the outside lane (3 lanes heading west on Cache Rd, in Lawton Ok.) when this female driver decided that she wanted my lane. As she began to pull into my lane (NO TURN SIGNAL) I began to move toward the curb and Honked my horn while beginning to brake. She jerked the wheel back to the left to return to her lane in which the vehicle to her left had begun to move into. the sudden jerk of the wheel and failure to look at traffic caused her to hit the other vehicle. All 3 of us pulled off into a parking lot, the Female stated that it was my fault (I was in her blind spot and that I startled her when I Honked my Horn at her...) I think she would have noticed me if the phone was not glued to her ear. I got back on my trike and left. She told me that I could not leave as I was a witness. I explained to her that I would not make a very good witness for her (Failed to clear the lane she was entering, Failed to Signal intent to change lanes, Careless Driving and on the Phone. I did however give my contact info to the driver she hit. I still don't see how she could miss me , I am lite up like a Christmas Tree.:Shrug:
