Do I have a chance of winning an accident case when a revised report makes the other driver look not at fault?

I have liability only and a woman broadsided my son damaging my fender behind the front wheel to my back door. Her damage was from the front bumper and side panel. My son was in the far right lane getting ready to make a right turn at a traffic light when a woman made a right turn from the center lane of the highway to turn into a shopping plaza when she struck my son. the highway goes from two lane into three where the right lane becomes the center lane and far right is for turns.
