as per my norm I've been in an accident like this

Basically its a 50/50 the person who hit her is suppose to be paying attention a little more to whats in front of them and most likely trying to beat the light.
Your GF however is making a turn instead of going straight ahead and "cutting off" traffic (your not but you understand I am sure) and your right its the wording thats going to get her. Cuase they will say she "should have saw her coming" and your GF did try to beat her to some extent but misjudged. The other car didnt come outa no where, your Girl saw it and said " I can make it" obv she couldn't.

When the guy t-boned me I was making the left and was found 100% fault, some guy said " I tried to beat the light and cut her off" yet the girl was flying and creamed me.
