You were at a stop sign with a car in front of you and they started to go and then slammed on their brake and you hit them who is at fault?
Well in occured at a low speed, do you know how much damages will cost. There was no damage to my car, but his cars bumper paint peeled off and it kind of crushed very little. We exchanged some information, but no insurance information yet. Is this going to cost a lot of money you think? The person behind has the right to be annoyed that the lead driver stopped abruptly, but the simple fact is, you're responsible for hitting the car in front of you in the situation you described.
