Washington doesn't impose a hard suspension waiting period before Ignition Interlock License (IIL) eligibility for second-offense DUI within 7 years, but installation timing, prior IIL violations, and concurrent administrative revocations control whether you can apply immediately or face a longer mandatory wait.
When Can You Apply for an Ignition Interlock License After a Second Washington DUI Within 7 Years?
Washington Department of Licensing (DOL) administrative revocations and court-ordered suspensions for a second DUI within 7 years run concurrently in most cases, not consecutively. You can apply for an Ignition Interlock License (IIL) immediately upon administrative revocation or court-imposed suspension unless prior IIL violations, other disqualifying suspensions, or refusal-based revocations extend your mandatory hard period.
RCW 46.20.385 governs IIL eligibility. For second-offense DUI within 7 years, DOL typically issues a 2-year administrative revocation for test failure (BAC .08 or higher) or 2-year revocation for refusal. Court-imposed suspensions vary by BAC level and prior history. If your prior DUI occurred within the past 7 years, the court suspension minimum is 90 days for BAC .08–.14, 120 days for BAC .15 or higher, or 150 days if the prior offense involved BAC .15 or higher. These periods overlap—your IIL application timing is controlled by whichever suspension takes effect first.
If you violated IIL terms during a prior suspension—driving without the device, tampering, failing rolling retests, or accumulating lockouts—DOL may impose a mandatory hard suspension period before new IIL eligibility. This hard period is not codified at a fixed day count statewide; it varies by violation severity and prior history. Contact DOL Driver Services at 360-902-3900 to verify your specific eligibility date if prior IIL violations appear on your driving record.
How DOL Administrative Revocations and Court Suspensions Stack for Second-Offense DUI
Washington separates administrative (DOL-imposed) and judicial (court-ordered) license actions. Both can apply to the same DUI arrest. DOL issues an administrative revocation under RCW 46.20.308 Implied Consent law based on BAC test results or refusal at the time of arrest. The court issues a separate suspension as part of criminal sentencing under RCW 46.61.5055.
For second DUI within 7 years, DOL administrative revocation is 2 years for test failure or refusal. Court suspension is 90 days minimum for BAC .08–.14, 120 days for BAC .15 or higher, or 150 days if your prior DUI involved BAC .15 or higher. These suspensions begin on different dates—administrative revocation starts when DOL processes the arrest report (typically 7–14 days after arrest), court suspension starts on sentencing date.
Because the suspensions run concurrently, your total restricted driving period under IIL is controlled by the longer of the two—typically the 2-year DOL revocation. IIL eligibility begins the day the first suspension takes effect, provided you have no disqualifying prior violations. You do not serve the DOL revocation fully, then start the court suspension. Install the ignition interlock device, file SR-22, pay the $100 IIL application fee, and you can drive under IIL terms immediately while both suspensions run in parallel.

Ignition Interlock Device Installation Requirements and Timing for Second DUI
Washington requires ignition interlock device (IID) installation by a DOL-approved provider before IIL issuance. The provider list is published at dol.wa.gov under Ignition Interlock Devices. Installation must occur before you submit the IIL application—the provider certificate is required documentation.
Installation cost is typically $100–$150. Monthly monitoring and calibration fees range $75–$100. For a second DUI within 7 years, RCW 46.20.720 mandates IID for the entire period of suspension or revocation, which is 2 years under DOL administrative revocation. If court-imposed suspension extends beyond 2 years due to aggravating factors, IID remains required for the full duration.
You cannot drive any vehicle without an installed IID during the IIL period. This includes employer vehicles, rental cars, or vehicles owned by family members. Driving a non-IID-equipped vehicle while holding an IIL results in immediate IIL revocation, extension of your mandatory IID period, and potential criminal charges under RCW 46.20.740 (driving while license suspended or revoked in the first degree). DOL does not grant IID exemptions for work vehicles or employer hardship—the device travels with you, not the vehicle registration.
SR-22 Insurance Filing Duration and Cost Stack After Second Washington DUI
Washington requires SR-22 insurance filing for 3 years following a second DUI within 7 years. The 3-year period begins on the date your driving privilege is reinstated or the IIL is issued, whichever comes first. SR-22 filing fee is typically $25–$50 one-time. Premium increases vary by carrier, age, and county but typically range $140–$240/month during the filing period.
You must maintain continuous SR-22 coverage for the full 3-year period. If your policy lapses or cancels, the carrier notifies DOL electronically within 10 days under RCW 46.29. DOL suspends your IIL or reinstated license immediately upon receiving the lapse notice. Reinstatement after an SR-22 lapse requires new SR-22 filing, payment of the $75 administrative reinstatement fee, and the 3-year clock resets from the new filing date.
If you do not own a vehicle, non-owner SR-22 insurance meets the filing requirement. Non-owner policies provide liability coverage when you drive a vehicle you do not own—rental cars, employer vehicles equipped with IID, or borrowed vehicles. Non-owner SR-22 premiums are typically lower than owner policies, ranging $50–$100/month depending on driving history and carrier. Dairyland, The General, Progressive, and Bristol West write non-owner SR-22 policies in Washington.
Total Cost of IIL Compliance for Second DUI Within 7 Years
Washington IIL compliance for a second DUI within 7 years requires five cost categories: IIL application fee, IID installation and monitoring, SR-22 filing and premiums, DUI alcohol/drug information school or treatment, and final reinstatement fee. Total cost over the 2-year IIL period plus 1 year of remaining SR-22 filing is approximately $7,500–$12,000.
IIL application fee is $100. IID installation is $100–$150 one-time, plus $75–$100/month monitoring for 24 months ($1,800–$2,400 total). SR-22 filing fee is $25–$50 one-time, plus premium increases of $140–$240/month for 36 months ($5,040–$8,640 total). DOL-approved Alcohol/Drug Information School (DIS) costs $150–$300, or substance abuse treatment ranges $500–$3,000 depending on program length and provider. Final reinstatement fee after the 2-year IIL period ends is $170 (DUI-specific reinstatement fee under RCW 46.20.311).
These costs are not optional. Failure to install IID, maintain SR-22, or complete court-ordered DIS/treatment extends your suspension period indefinitely. DOL will not issue final unrestricted license reinstatement until all program completion certificates, proof of SR-22 filing start date, and fees are submitted and verified.
What Happens If You Violate IIL Terms During Second-Offense DUI Suspension
Driving without an installed IID while holding an IIL is a gross misdemeanor under RCW 46.20.740. First violation typically results in IIL revocation, extension of mandatory IID period by 6 months to 1 year, and potential jail time up to 364 days. Second violation during the same IIL period converts to a felony driving while license suspended charge in some counties.
IID device violations—tampering, failing rolling retests, accumulating lockouts, or circumventing the device—trigger automatic DOL review. Three failed rolling retests within a calibration period, five lockouts within 30 days, or any evidence of bypass attempt results in IIL suspension and mandatory hearing. DOL extends your IID requirement by the length of time the violation period lasted, plus additional mandatory hard suspension before new IIL eligibility.
Missing two consecutive DUI court program classes or treatment sessions triggers program non-compliance notification to the court and DOL. The court may issue a bench warrant. DOL suspends IIL until proof of re-enrollment and makeup completion is submitted. The 2-year IIL clock does not advance while you are out of compliance—time freezes until you cure the deficiency and pay reinstatement fees.
Path to Full License Reinstatement After Second Washington DUI Within 7 Years
Full unrestricted license reinstatement after a second DUI within 7 years requires completion of the 2-year IIL period, proof of continuous SR-22 filing for at least 2 years (with 1 additional year remaining), completion of all court-ordered DUI programs and treatment, payment of the $170 reinstatement fee, and retest (written knowledge and driving skills test).
RCW 46.20.311 requires both written knowledge retest and driving skills retest for second DUI within 7 years. You must schedule the retest at a DOL licensing office after your IIL period ends. Bring proof of DIS or treatment completion, SR-22 certificate showing continuous coverage start date, final court disposition showing all fines and conditions satisfied, and IID removal certificate from your provider. DOL processes reinstatement applications in 5–10 business days after all documentation is verified.
Your SR-22 filing requirement continues for 1 additional year after full license reinstatement. If you cancel SR-22 before the full 3-year period ends, DOL suspends your license again immediately. The 3-year SR-22 clock runs from IIL issuance date, not reinstatement date. Track your filing start date carefully—most carriers send anniversary reminders, but responsibility to maintain coverage rests with you.
