Driving home after several beers over several hours, I was t-boned by a drunk driver that ran a stop sign. I was very forth coming with the officers as I did not believe I could be over the limit. At the hospital the nurses took blood and gave it to the officers. No one asked me for consent. Turns out I was a little over the limit. I was not charged or arrested. I believe that they could still come back to me on this. How long do they have to charge me and is it likely that I will be charged even though I'm a victim.
