In Washington, DC, if you have been charged with a DUI, DWI, or OUI, and it is your first offense, you have no criminal record, there was no accident, you did not do anything really offensive such as yelling and cursing at the police, and had a blood alcohol concentration (BAC) of less than 0.1%, you may be entitled to a Deferred Sentencing Agreement (DSA).  With a DSA you will plead guilty to the DUI and go to probation for a certain period of time.  If you successfully complete the probation, the charges will be dismissed, and you will have the conviction removed from your record.
