I was travelling southbound on a main urban street. I was approaching an interesting with a feeder road to a major freeway. I was in a line of cars making a right hand turn onto this feeder. Just before I was about to start turning right, the Tucson Hybrid suddenly and unexpectedly smalled on the brakes and I came to a full stop. I was HIT FROM BEHIND. There was minimal damage to the car that hit me. My car had damage to some plastic components on the bottom of my rear bumper. Total cost to repair this damage was $785. No insurance claim was filed.
