If im making a turn at a yellow light and im almost through with my turn and someone hits me in the back passenger side of my vehicle who is at fault?
Probably you, based on what you posted, but an accurate answer would require more details. You NEVER have the right of way to make such a turn unless you can make it safely, so the fact you were hit pretty much answers that.
Chris is correct
Need much more details
Who was ticketed
Did light turn red while you were in the intersection etc etc
