DUIs throughout the State of Washington are not prosecuted similarly. Where you were arrested and by which law enforcement agency makes a difference, not only in the outcome of your case but in terms of what consequences you could be facing within the first 24 to 72 hours. This particularly applies to DUI arrests made within the city of Seattle but in many other jurisdictions as well.
