The rules

What Washington requires

Washington issues a separate license class for this — the Ignition Interlock Driver License. You may apply at any time, including straight after arrest and before the revocation begins, and it lets you drive normally as long as every vehicle you drive has a device. Work vehicles count too if your employer owns, leases or maintains them.

  • First offense: For the remainder of the suspension, revocation or denial — you may apply at any point, including immediately after arrest
  • Lockout threshold: Set by the device standard adopted by the Department of Licensing
  • Program run by: Washington State Department of Licensing

Why Washington asks for the device

Federal crash records are the backdrop to the rules on this page. Read the share with care though: it depends heavily on how often police obtain an alcohol test, and that varies enormously between states.

Questions

Interlock questions in Washington

Is an ignition interlock mandatory in Washington?

Washington issues a separate license class for this — the Ignition Interlock Driver License. You may apply at any time, including straight after arrest and before the revocation begins, and it lets you drive normally as long as every vehicle you drive has a device. Work vehicles count too if your employer owns, leases or maintains them. As for how long: for the remainder of the suspension, revocation or denial — you may apply at any point, including immediately after arrest.

How much is an interlock device per month in Washington?

Washington publishes its own figures rather than leaving it all to vendors: up to $250 to fit the device and $150 to $191 a month while it stays on the car. Removal is billed separately at the end of the term.

What are the consequences of an interlock violation in Washington?

A recorded event is not automatically a violation, and that distinction decides most cases. Programs differ in what they count and how they count it: some add time per event, others ignore single events and act on a pattern, and several give you a written escape where a retest within five or ten minutes comes back clean. What is uniform is that the decision is made by Washington State Department of Licensing from the vendor's report, not at the roadside. The mechanics, state by state and with the statute on each, are on our page about violations and lockouts.

How do I get the interlock restriction off my license in Washington?

Not at the workshop, and not on the date in your paperwork. The state releases you first and the device comes out last: you finish the term including anything added to it, sit a final data download at the service center, let Washington State Department of Licensing review the record, take what it issues to a licensing office to lift the restriction, and only then book the removal. Most programs also require a clean window before any of that starts — 180 days in Washington, the last 30 in New Jersey, three months in Maryland.

What blood alcohol level will fail an interlock in Washington?

Washington does not fix the number in the statute itself — it is set by the certifying agency in the device standard, and in practice sits between 0.02% and 0.025% BAC. Either way it is far below the 0.08% driving limit, which is why one drink shortly before a test is enough to fail it: the device is testing whether you drank, not whether you are impaired.

Is there an alternative to an ignition interlock device in Washington?

Sometimes, and it is usually stricter rather than easier. The common substitute is continuous alcohol monitoring — a transdermal ankle bracelet that watches the person instead of the car, all day rather than at the ignition. North Carolina writes the trade directly into sentencing: 120 days of monitored abstinence can cut a 30-day minimum to ten, and 90 days can replace a seven-day term. The other alternative is not driving at all, which some states allow you to serve out instead, and which costs you the license for the whole period rather than the device.

Where can I get an ignition interlock device installed in Washington?

We index 152 certified installation points across 71 Washington cities, run by 5 approved providers, with the densest coverage in Tacoma, Vancouver, Yakima. Install with a provider the state approves rather than the nearest pin on the map: time on an unapproved device does not count toward the term.
