My question involves an injury that occurred in the state of: South Dakota

I was riding my motorcycle when a man in a truck traveling the opposite direction as me turned left in front of me and I impacted the passenger side of his truck. I am bruised and sore and my bike is surely totaled. The man claims I had my turn signal on to turn onto the same road which he was turning. Even if my signal was on and I turned we still would have collided.

My question is, even if my signal was on shouldn't he have been cited for failure to yield or something along those lines?
