One of the more controversial areas in Washington DUI law is the deferred prosecution. Under RCW Chapter 10.05, a person who truly believes they suffer from either alcohol or drug addiction or mental illness can petition the court for a dismissal of his or her DUI charge. In exchange, that person must undergo an intensive alcohol, drug or mental health treatment program, complete the program successfully and follow all conditions of the court for a period of five years. Successful completion likely means a dismissal. Failure almost certainly means a conviction.
