Washington DUI Causing Injury: Vehicular Assault and IIL Eligibility

Washington charges DUI causing serious bodily injury as vehicular assault under RCW 46.61.522, a felony separate from standard DUI. Your DOL administrative suspension runs independently from the criminal case. Most defendants assume they must wait for trial resolution before applying for an Ignition Interlock License, but Washington allows IIL applications during pending felony cases if the underlying triggering event was alcohol or drug-related driving. The criminal conviction timeline stretches months or years. The administrative suspension starts within 60 days of arrest if you failed or refused the breath test. DOL does not wait for your criminal case to close before processing your IIL application. The two systems operate in parallel. Vehicular assault convictions carry mandatory minimum IID periods longer than standard DUI. First-offense vehicular assault requires ignition interlock for 5 years minimum compared to 1 year for standard DUI. Second or subsequent offense pushes the period to 10 years. The IIL you receive during the suspension period transitions directly into this post-conviction mandatory period without interruption.

DOL begins accepting IIL applications the day your administrative suspension takes effect, regardless of pending criminal charges. If you refused the breath test, your administrative revocation lasts 1 year with immediate IIL eligibility. If you failed the test (BAC .08 or higher), the revocation is 90 days for first offense, with IIL available from day one. Vehicular assault charges do not create additional administrative waiting periods beyond the standard DUI refusal or failure consequences. The $100 IIL application fee is identical. The required documentation is identical: SR-22 filing, proof of DOL-approved IID installation, completed application form, payment. DOL approval does not depend on criminal case resolution. You can hold an active IIL while facing pending vehicular assault charges. The restriction: you must drive only IID-equipped vehicles, and any new alcohol-related arrest while on IIL triggers immediate revocation.

The IIL you receive during administrative suspension becomes part of your mandatory post-conviction ignition interlock compliance period. Washington does not give credit for IIL time served before conviction. A vehicular assault conviction resets the clock. First-offense vehicular assault under RCW 46.61.522 requires 5 years of ignition interlock from the date of conviction, not the date of arrest. If you held an IIL for 18 months during the pretrial period, you still owe the full 5-year post-conviction period. Second offense or vehicular homicide cases extend the mandatory period to 10 years or longer. Your IIL converts automatically into the post-conviction restricted license once DOL receives notice of the conviction and the court's ignition interlock order. The device stays installed. The SR-22 filing continues for the full conviction-based period, typically 3 years minimum from conviction date per RCW 46.29.090.

Prosecutors frequently reduce vehicular assault charges to standard DUI or reckless driving as part of plea agreements. The reduction changes your mandatory IID period dramatically. Standard DUI carries 1 year IID for first offense, 5 years for second, 10 years for third. Reckless driving alone does not require ignition interlock unless the court specifically orders it as a condition of probation. DOL honors the conviction entered, not the original charge. If your plea agreement results in first-offense DUI instead of vehicular assault, your post-conviction IID requirement drops to 1 year. If you've already held an IIL for 14 months during pretrial suspension, DOL gives no retroactive credit, but the remaining compliance period shrinks to the lesser conviction's requirement. Negligent driving in the first degree (a common reduction from DUI causing injury) does not trigger ignition interlock at all unless the court specifically imposes it. Your IIL issued during the administrative suspension period would expire at the end of the administrative revocation, with full reinstatement available once you satisfy DOL's requirements and pay the $75 base reinstatement fee plus any conviction-related fees.

Washington requires SR-22 filing for 3 years following any alcohol-related license action, measured from the date DOL processes your reinstatement or issues your IIL. Vehicular assault does not extend the standard 3-year SR-22 period unless your conviction includes additional violations (hit and run, driving while suspended, uninsured driving) that stack separate filing requirements. Your SR-22 filing must remain active and continuous throughout the entire period. A lapse triggers automatic suspension under Washington's electronic insurance verification system. Carriers report cancellations to DOL in real time. Most drivers receive suspension notice within 10 days of SR-22 lapse. SR-22 premium impact varies by carrier and your specific conviction details. Vehicular assault appears on your driving record as a felony DUI-related offense. Expect annual premiums in the range of $2,400–$4,800 during the filing period for minimum liability coverage. Non-owner SR-22 policies (if you do not own a vehicle) typically cost $400–$900 annually but do not satisfy the ignition interlock requirement — IID requires a vehicle you own or have regular access to.

Installation fees run $100–$200 depending on provider. Monthly monitoring and calibration fees average $70–$100. Over a 5-year vehicular assault IID compliance period, total device costs reach $4,200–$6,000 before insurance. Add SR-22 filing fees ($25–$50 one-time per carrier) and elevated premiums. Total cost over the 5-year post-conviction period frequently exceeds $15,000 when you combine IID monitoring, SR-22 premiums, reinstatement fees, and court-ordered restitution or treatment program costs. DOL does not waive IID requirements for financial hardship. Washington law treats ignition interlock as a mandatory safety condition, not a discretionary penalty. Payment plans for device costs exist through most DOL-approved providers, but skipped payments trigger compliance violations reportable to DOL and the court.

Driving any vehicle without an installed IID while holding an IIL constitutes driving while license suspended in the first degree under RCW 46.20.342, a gross misdemeanor. Conviction adds a new mandatory 1-year suspension on top of your existing vehicular assault consequences. Tampering with the device, attempting to bypass it, or allowing another person to provide a breath sample triggers IIL revocation and extends your total compliance period. DOL receives violation reports directly from the IID provider whenever the device logs a failed start attempt (BAC above the programmed threshold, typically .025), a missed rolling retest, or physical tampering. Three failed start attempts within 6 months or one tampering event results in IIL revocation. You return to hard suspension status for the remainder of your original revocation period plus any additional time DOL imposes for the violation. Reinstatement after IIL revocation requires a new application, new fees, proof of continuous sobriety, and completion of additional treatment if ordered.
