What does a DUI really cost? If you are arrested for DUI in Washington and look up the fine, you may find that the statutory base fine for a first offense is $350. But that number is almost meaningless on its own. By the time mandatory assessments, device requirements, insurance surcharges, license fees, and treatment costs are added in, a first-offense conviction may total well over $12,000 to $15,000. That figure doesn’t include what could happen to your career.
At DUIHeroes, we’ve handled DUI cases throughout Snohomish County for over 20 years. We’ve watched clients absorb costs they never anticipated because they didn’t have the full picture before they made decisions.
This is that picture, updated for 2026 Washington law.
The Mandatory Fines Are Just the Starting Point
Under RCW 46.61.5055, Washington’s DUI penalty statute, the true mandatory minimum for a first offense isn’t $350. It’s $990.50, reflecting what happens after the base fine is stacked with four mandatory additions: the Public Safety and Education Assessment, the Washington State Toxicology Lab fee, the Title 46 penalty, and the court funding fee. Courts don’t itemize these separately in most sentencing orders; they appear as a single number that looks like a fine.
That floor rises quickly depending on the circumstances. If your blood alcohol content was at or above 0.15%, or if you refused a breath or blood test, the mandatory minimum jumps to a higher tier under the same statute, along with increased mandatory jail minimums. Whether your case is heard in Snohomish County District Court (Everett Division), which handles arrests made by the Snohomish County Sheriff or Washington State Patrol, or in Everett Municipal Court, which handles arrests made within Everett city limits by Everett Police, the judge, your BAC, and your case history all influence the final number above the statutory floor.
The Ignition Interlock Device Costs More Than Most People Expect
Washington requires a minimum one-year ignition interlock device installation for a first-offense DUI. An ignition interlock device (IID) is a breath-testing unit wired into your vehicle’s ignition that requires a clean breath sample before the car will start. A Washington Joint Legislative Audit and Review Committee report approved April 8, 2026 found that IID costs run approximately $2,700 per year for the average driver, covering installation, monthly lease, required calibration appointments, and removal.
Breaking it down: installation runs roughly $70 to $150, monthly lease fees range from $60 to $90, and calibration is required every 30 to 60 days at an additional cost. A failed test or a missed calibration appointment isn’t just inconvenient. It can extend the mandatory IID period and trigger penalty fees on top of the extension.
Washington’s Department of Licensing offers a financial assistance program for income-qualified drivers that reimburses the IID provider up to $80 per month, but many drivers don’t meet the eligibility threshold.
Insurance Costs Follow You for at Least Three Years
A DUI conviction triggers a mandatory SR-22 filing requirement. An SR-22 is a certificate of financial responsibility filed by your insurer directly with Washington’s Department of Licensing, confirming you carry the state-required minimum coverage. Washington requires this filing for three years from the date of reinstatement eligibility, and a single coverage lapse restarts the clock with no grace period.
The SR-22 filing fee itself is modest, typically $15 to $50. The real cost is the high-risk premium classification your insurer assigns the moment the conviction appears. Based on 2026 rate data from MoneyGeek using Quadrant Information Services figures, Washington drivers with a DUI pay an average of $178 per month for full coverage. That’s roughly $106 per month above the clean-record baseline, or about $3,816 in additional premium costs over the mandatory three-year window. Some carriers won’t renew your policy at all, which means shopping for coverage in a high-risk pool where rates are worse.
License Reinstatement, Treatment Programs & Lost Income
License reinstatement carries a $170 DUI-specific reissue fee payable to the Department of Licensing, separate from the SR-22 filing. But how quickly you reach reinstatement depends on a deadline most people miss. After a DUI arrest in Washington, you have seven days to request a Department of Licensing administrative hearing to contest the license action. Miss that window, and the suspension or revocation becomes automatic: 90 days on a positive breath test above the legal limit, or one year on a first test refusal. A refusal suspension isn’t a minor inconvenience. One year without a license means one year of rideshare, transit, or borrowed transportation costs layered on top of everything else.
Courts also mandate several completed programs at the defendant’s expense:
- Alcohol and drug assessment: Required before sentencing and paid by the defendant, typically $100 to $200
- Substance abuse information school: Mandatory attendance, fees paid by the defendant
- Victim impact panel (VIP): A one-session program typically run by a local county-based provider, with a separate registration fee (commonly $35-50)
A DUI conviction in Washington stays on your record permanently and can’t be vacated. Every background check, every professional license renewal, every job application that asks about criminal history carries it forward. The employment and licensing consequences, particularly in fields like healthcare, education, commercial driving, and financial services, represent the longest-lasting financial impact of the conviction. That impact is impossible to quantify at sentencing and nearly certain to exceed the court-imposed costs over time.
What the 2026 Law Changes Add to the Cost Picture
Effective January 1, 2026, Washington extended the felony DUI lookback period from 10 to 15 years. The lookback period is the window within which prior DUI offenses count toward the felony threshold. Before this change, a prior offense from 11 years ago wouldn’t count. Now it does. If you have prior DUI history from within the past 15 years, what would have been charged as a gross misdemeanor under prior law may now be filed as a Class B felony, carrying fines up to $20,000 and up to 10 years in prison. Felony DUI cases in Snohomish County are heard in Snohomish County Superior Court.
The same 2026 legislative changes introduced a new sentencing alternative for certain felony DUI convictions under RCW 9.94A.661, oriented toward treatment rather than incarceration. Whether a defendant qualifies depends on case-specific factors, but it can meaningfully affect the overall cost structure for those who do. On the IID side, 2026 rules now allow defendants to raise an employer exemption as an affirmative defense to operating a vehicle without a functioning IID. The exemption applies when driving an employer-owned vehicle as a condition of employment, but doesn’t apply to self-employed individuals unless the vehicle is used exclusively for work purposes. If you drive for work, whether this exemption applies to your situation is worth discussing with a defense attorney before assuming you’re covered.
Why Working with an Attorney Can Change the Math
The costs outlined above are consequences of conviction, and a skilled defense is the one factor that can reduce or eliminate them, whether through a dismissal, a reduction to a lesser charge, or a negotiated outcome that avoids the highest-tier penalties entirely.
At DUIHeroes, we’ve achieved an average 95% reduction or dismissal rate for first-offense DUI charges since 2009.* We practice DUI law exclusively, and our team includes two former prosecutors who understand how the state builds its case from the inside. Jonathan Dichter, our founding attorney, is a Qualified Instructor for the NHTSA Standardized Field Sobriety Testing course, the same training Washington law enforcement officers receive, which means we can evaluate the technical foundation of the state’s case: whether the officer administered the field sobriety tests correctly, whether the breath test device was properly calibrated, and whether the stop itself was lawful. Those aren’t abstract legal arguments; they’re the kinds of technical challenges that produce dismissals and reductions. Jonathan also authored Innovative DUI Trial Tools (7th ed., James Publishing), a national strategy guide used by DUI attorneys across the country, and serves as Washington State Delegate for the National College for DUI Defense.
When you add up mandatory fines, IID costs, insurance surcharges, license fees, and treatment program fees, a first-offense DUI conviction in Washington may reach $12,000 to $15,000 or more over five years, and that's before factoring in the harder-to-quantify cost of a permanent record on employment and professional licensing, which can outlast every other item on this page. A conviction that's reduced or dismissed doesn't just lower a single number; it can eliminate the IID requirement, shorten or avoid the insurance surcharge period, and keep a permanent record off your background check altogether. That's the kind of outcome an experienced Snohomish County DUI attorney is positioned to pursue from the moment you're arrested.
