Should I just plead guilty to my DUI?

No. Although at first you may be tempted to go this direction, you must keep in mind that the ramifications of a Washington State DUI conviction are long term and severe, and should not be entered into lightly. (i.e. driving license and insurance consequences, ignition interlock requirements and exclusion from Canada among many others) The DUI mandatory minimums provide the sentencing Judge with very little flexibility. It is always best to obtain an experienced Washington State DUI attorney before entering any plea.
