Can I sit out the the Ignition Interlock Device (IID) period on a DUI?

Yes, you can sit out – all but four (4) months. If the Ignition Interlock Device is required because of a DUI, Physical Control, 2nd or subsequent Reckless or Negligent Driving (within/7) conviction it does apply. A 4-month certification is required from the ignition interlock device installer/vendor showing compliance with RCW 46.20.720 before the interlock requirement can be removed. See Form: 4 Month IID Compliance Form

The ignition interlock restriction will remain in effect until the Department of Licensing (DOL) receives a declaration from the person’s ignition interlock installer/vendor certifying that there have been none of the following incidents in the four consecutive months prior to the date scheduled for removing the interlock:

(a) An attempt to start the vehicle with a breath alcohol concentration of 0.04 or more;

(b) Failure to take or pass any required retest; or

(c) Failure of the person to appear at the ignition interlock device vendor when required for maintenance, repair, calibration, monitoring, inspection, or replacement of the device.
