dui hit and run
I was ran off the road and my car went into a ditch. I walk home and called 911. Later I was arrested for dui,hit and run and failer to notify of an accident. I said I called the police myself. When I was taking to the station my blood was taken to see if my blood alcohol was over the limit. I was told the result would be in 2 weeks. I could also get a police report in 2 weeks. I believe I was under the limit but I was charged with a dui anyway. Can you tell me what I should do. Are the three charges valid?
