Auto Insurance Claims: subrogation, oncoming vehicles, other vehicles

Question
I was in an auto accident a month ago - I was turning left on a green light when a woman ran a red light and hit me.  No witnesses, but she admits to running a yellow light.  The insurance company took pics of the intersection which helps
my case.  My agent said it's so blatant from the pics that she is at fault. Now it is in subrogation.  My question is,  is it possible that both insurances can come back to us and say we are both responsible for our own damage?  We both have the same insurance company.


Answer
It is possible that you may be found equally at fault or that you may be found 100% at fault.
The reason that I say this is if she had a yellow light and you turned left in front of her, the other driver would not be at fault.  The vehicle turning left has 100% responsibility to yield to oncoming vehicles unless those other vehicles have a red light.  So the big question here is, Yellow or Red?  If it cannot be proven that she had a red light, then you may bear some or all responsibility.
Sorry.

Good luck and I'd appreciate your feedback.
