You were at a stop light waiting to turn right and you were looking left and waiting for the car in fron of you to turn you think you just bumped the curb but once turned the other car honked at me?

If you hit the other car they would have followed you and gotten your information to file a claim. But you must remember that you were at a stop light. It could have been clear and you just were not looking and the car behind honked their horn to tell you that it was clear and that they were in a hurry. Good luck and God Bless:)
