If you are arrested in the District of Columbia on suspicion of drunk driving, you will most likely be taken to an MPD District station where you will be booked and placed in a holding cell until you are sober.  You will probably be released from there and given a summons to appear in traffic court.  Unless there is was an accident or something else involved, you will probably not be taken to the Central Cell Block on Indiana Avenue. If you are convicted of a DWI or DUI and blew less than 0.20% on a breath score, and this was your first offense, you most likely not go to jail.  You may get a suspended sentence with probation. Your DUI defense attorney should explain this to you.
