03The process

How a DUI case moves through the system in Washington

The typical sequence, in general terms. Timing and details differ by county and by case.
  1. Arrest and booking

    Police arrest a driver on suspicion of DUI and take the person to the local jail, where booking records the arrest, the charge and the times.

  2. Release

    A person is released after posting bail, on their own recognizance, or after a hold. Amounts and timing differ by county.

  3. License action

    In writing within 7 days after the notice, to the Department of Licensing, with a $375 fee (waivable if you cannot pay). If mailed it must be postmarked within 7 days.

  4. Arraignment

    The first court appearance, where the charge is read and a plea (guilty, not guilty or no contest) is entered.

  5. Pretrial resolution

    A case can end in a plea to a reduced charge, in a diversion or deferred program where the state has one, in a trial, or in a dismissal, depending on the state and the facts.

  6. Sentencing or trial

    For a first offense, Washington's statute provides jail of 24 hours to 364 days, a fine of $350 to $5,000, and a license suspension of 90 days. See the penalties table above.
