Washington DUI Laws

Driving under the influence (DUI) of alcohol or other intoxicants, including marijuana and even prescription drugs, is a serious offense in Washington. Even a first offense can result in a one-year jail sentence and a fine of up to $5,000. However, the most severe sentences are reserved for those whose actions result in the death or bodily injury of another. And regardless of the severity, those convicted of a DUI in the state will almost always have their driver license suspended for at least 90 days, on up to three years and a possible revocation for repeat offenders.

Ignition Interlock Driver License (IIL)

As in most states, Washington offers those convicted of a DUI the limited opportunity to drive using an ignition interlock device (IID), which requires the driver to submit a valid (i.e. sober) breath sample before starting the car. To be eligible for the program in Washington, you must meet the following requirements:

  1. An arrest or conviction on charges of DUI, physical control involving drugs or alcohol, reckless driving, vehicular assault/homicide involving drugs or alcohol
  2. Washington State residence and valid Washington driver license
  3. Current suspension doesn't include minor in possession or habitual traffic offender charges

To apply, first get an IID installed on your vehicle (the Department of Licensing will provide proof of installation), get proof of financial responsibility, and send in your restricted driver license application along with payment.
