I am trying to determine who is at fault in the following accident. I was approaching a 4-way stop, and was going to turn left. There was a left turn lane available. A motorcyle behind me was also going to turn left. The motorcylce behind me got into the left turn lane before me. With my turn signal on, I turned into the left turn lane. The motorcycle behind me had to lay the bike on its side to avoid hitting me in the rear. The vehicles did not ever come into contact with each other.
Am I liable for the damage to the motorcycle or injuries to the biker?
