If I was charged with a DWI 9 years ago but never went to court, what are my options now?

Well you need to clear up the bench warrant.  Yes, it is odd that it took them 9 years to catch up with you but sometimes the wheels of justice grind slowly.  Eventually they do catch up with you.  What you need to do is surrender yourself voluntarily and it may be a very good idea for you to hire an attorney to run interference for you. I am still trying to figure out how you could have thought that the matter was "taken care of" with out paying a fine or going to court.  But be that as it may you need to address it now.  Depending on what evidence they still have on the matter and in the court file, you could be in a better position that the warrant implies.  Get legal help.  Good luck.
