Ignition Interlock Driver’s License (IIL) for DUI Convictions in Washington State

Ignition Interlock Licenses in Tacoma, WA: How to Keep Driving After a DUI Suspension

A DUI conviction or administrative suspension in Washington often triggers an immediate and frightening consequence: the loss of your driver’s license. For many people in Tacoma and Pierce County, that loss threatens employment, childcare, medical appointments, and basic daily life.

What many drivers do not realize is that a license suspension does not always mean you must stop driving altogether. Washington law allows certain drivers to apply for an Ignition Interlock Driver License, commonly called an IIL. This restricted license can allow you to drive legally during a suspension—but only if you follow the rules precisely.

At Smith & White, PLLC, we regularly help clients navigate the ignition interlock process after a DUI arrest or conviction. This guide explains how the IIL works, where people make costly mistakes, and how to protect yourself from additional charges while your case or suspension is pending.

What Is an Ignition Interlock Driver License in Washington?

An Ignition Interlock Driver License is a restricted license issued by the Washington Department of Licensing. It allows eligible drivers to operate a vehicle during a DUI-related suspension or revocation, provided that an ignition interlock device is installed in every vehicle they drive.

The ignition interlock device requires the driver to provide a breath sample before the vehicle will start and at periodic intervals while driving. If alcohol is detected above a preset threshold, the vehicle will not operate.

The key point is this: the IIL does not restore your regular license. It is a limited, conditional privilege that only applies if you strictly comply with Department of Licensing and court requirements.

Common Mistakes That Lead to New Charges

We routinely see people charged again—not because they intended to violate the law, but because they misunderstood it.

Common mistakes include:

Driving before the IIL is officially issued
Driving a vehicle without an IID, even briefly
Assuming an IID installation alone authorizes driving
Missing calibration or maintenance appointments
Using alcohol-containing products before testing
Failing to document device malfunctions

Law enforcement often treats ignition interlock violations seriously. What starts as a compliance issue can quickly become a new criminal case.

Who Qualifies for an Ignition Interlock License?

You may be eligible for an Ignition Interlock Driver License if:

You are a Washington resident, and
You hold either a valid Washington driver’s license or a valid out-of-state license, and
Your license is suspended or revoked due to a drug- or alcohol-related offense.

Common qualifying offenses include:

Driving Under the Influence (DUI)
Physical Control of a Vehicle While Under the Influence
Reckless Driving involving alcohol or drugs
Vehicular Assault involving alcohol or drugs
Vehicular Homicide involving alcohol or drugs

Suspensions for unrelated reasons—such as unpaid tickets, medical conditions, or failure to appear—require different remedies and are not covered by an IIL.

When Should You Apply for an IIL?

Timing matters more than most people expect.

In many cases, we recommend applying for the IIL approximately one week before the suspension takes effect. This often allows enough processing time to avoid a gap where you are legally unable to drive.

Applying too early can also cause problems. If the Department of Licensing has not yet processed the suspension, your application may be rejected as premature.

Because every case is different—especially when there is both a court case and an administrative DOL action—this is one area where legal guidance can prevent unnecessary delays.

How to Apply for an Ignition Interlock Driver License

The application process involves several steps. Missing any one of them can result in delays or unintentional violations.

Installing an Ignition Interlock Device

You must install a state-approved ignition interlock device in every vehicle you intend to drive. The installer provides proof of installation to the Department of Licensing.

Not all devices or providers perform equally. Over the years, we have seen fewer compliance issues when clients use established providers with consistent reporting practices and responsive customer service. While Washington approves multiple vendors, reliability and documentation matter more than price alone.

Your attorney can help you understand what the court and DOL expect so that installation records are properly transmitted and preserved.

Proof of Financial Responsibility (SR-22)

You must file proof of financial responsibility, commonly known as an SR-22. This is an insurance certificate showing that you meet Washington’s minimum liability requirements.

Many standard insurers offer SR-22 filings, though some drivers use specialty providers. The important issue is accuracy and continuity. Any lapse can trigger additional suspension issues.

Submitting the IIL Application

You must submit the restricted license application to the Department of Licensing along with the required fee. Errors on the application can slow approval and leave you unable to drive legally.

What the IIL Allows—and Does Not Allow—You to Do

Once approved, the IIL allows you to drive vehicles equipped with a compliant ignition interlock device. You must carry the IIL with you whenever you drive.

The IIL does not override:

Court-ordered restrictions
Commercial driver’s license suspensions
Other non-DUI-related license limitations

Driving outside the scope of your IIL can result in new criminal charges.

Employer Vehicle Exemptions

If your job requires driving an employer-owned vehicle, your employer may complete an Employer Declaration for Ignition Interlock Exemption. This can allow you to drive employer vehicles without an IID during work hours.

This exemption is narrow. It does not apply to vehicles you own or lease, and it only applies while performing job-related duties.

Court-Ordered IID vs. Ignition Interlock License

This is one of the most common sources of confusion.

A court may order you to install an ignition interlock device as a condition of release or sentencing. That order does not automatically authorize you to drive.

Separately, the Department of Licensing controls whether you are legally permitted to drive during a suspension. Without an IIL or a valid license, driving—even with an IID installed—can still be illegal.

In some cases, these timelines overlap in ways that extend how long you must maintain the device. Understanding how court orders and DOL actions interact is critical.

Cost and Financial Assistance

The cost of an ignition interlock license and device is often the biggest concern.

Typical expenses include:

Installation and monthly IID fees
SR-22 insurance premiums
Department of Licensing fees

Washington offers limited financial assistance programs for qualifying individuals. Eligibility depends on income and documentation, and assistance must be requested properly.

A Realistic Example

A Tacoma-area trades worker loses his license after a DUI conviction. His job requires daily driving. By installing an ignition interlock device, applying for an IIL at the correct time, and following all reporting requirements, he avoids additional charges and keeps working during the suspension period.

That outcome depends on doing everything correctly the first time.
