Washington requires both SR-22 and an ignition interlock device for most DUI convictions. Here's how the combined requirement affects your insurance, what carriers write this coverage, and what you'll pay after your IIL period ends.
What Washington's Combined SR-22 and IIL Requirement Actually Means
Washington requires SR-22 filing for three years after license reinstatement following a DUI, while the Ignition Interlock License (IIL) period runs separately — typically one year minimum for first offenses, longer for repeat violations. You carry both requirements simultaneously during the IIL period, then continue SR-22 filing alone after device removal.
The IIL allows you to drive during what would otherwise be a suspension period, but only in vehicles equipped with an approved ignition interlock device. Your SR-22 filing proves continuous liability coverage to the Washington Department of Licensing throughout both periods. Letting either requirement lapse resets both timelines to zero and triggers immediate license suspension.
Most carriers writing post-DUI coverage in Washington charge $15–$35 monthly for SR-22 filing on top of elevated DUI rates. The device itself costs $75–$150 for installation and $60–$90 monthly for monitoring — your insurance premium and device fees are separate line items. Drivers exiting IIL after one year still face two more years of SR-22 filing and elevated insurance rates before reaching standard-risk pricing.
How the IIL Period Affects Your Insurance Rate Recovery Timeline
Your insurance rate starts dropping immediately after conviction, but recovery happens in stages tied to time elapsed, not IIL completion. A first-offense DUI in Washington typically triggers a 70–110% rate increase at filing. After 12 months conviction-free, most carriers reduce that surcharge to 50–75%. After 24 months, it drops to 30–50%. Full standard-risk pricing returns 36–60 months post-conviction, depending on carrier underwriting rules.
Completing your IIL requirement after one year does not reset this timeline or trigger an immediate rate drop. The rate reduction is anchored to your conviction date, not your device removal date. Drivers often expect their premium to fall sharply once the device is removed — it doesn't. What changes is you stop paying $60–$90 monthly for device monitoring, which feels like a rate decrease but isn't reflected in your insurance bill.
Your best rate improvement opportunity happens at your first policy renewal after exiting IIL. That's when you can shop carriers who view 12+ months of clean driving with an interlock device as a strong risk signal. Progressive, GEICO, and The General actively write post-IIL drivers in Washington and offer competitive renewal rates to drivers with one year violation-free. Staying with your current carrier instead of shopping at this milestone typically costs $40–$80 monthly — $480–$960 annually — compared to the lowest available rate for your profile.

Which Washington Carriers Write SR-22 During Active IIL Periods
Not all carriers writing SR-22 in Washington will write policies for drivers on active Ignition Interlock Licenses. Progressive, The General, and Bristol West (a Farmers subsidiary) all write combined SR-22 and IIL coverage. GEICO writes SR-22 in Washington but typically declines new applications during active IIL periods — they'll consider you after device removal. State Farm and Allstate route most DUI and IIL business to non-standard subsidiaries or decline entirely.
Carriers writing IIL coverage in Washington charge $110–$190 monthly for state minimum liability ($25,000/$50,000/$10,000) with SR-22 filing included. Full coverage on a financed vehicle adds $70–$140 monthly depending on vehicle value and your specific violation details. These are post-DUI rates — your premium before the violation was likely $60–$95 monthly for the same liability-only coverage.
The carrier you're assigned during IIL is not necessarily the carrier offering you the best rate after device removal. Most drivers stay with their IIL-period carrier out of inertia, unaware that their rate could drop $50–$90 monthly by shopping at the 12-month mark. The General and Progressive both offer renewal discounts to drivers completing IIL without incident, but you only benefit if you actively request a re-quote and compare it against competitors.
What Happens to Your SR-22 Filing After IIL Ends
Your SR-22 requirement continues for three years from your license reinstatement date, which is typically the day your IIL was issued. If you received a one-year IIL, you still carry SR-22 for two more years after device removal. If your IIL was extended to 18 months due to violation or non-compliance, your SR-22 continues 18 months beyond that. The filing clock does not pause during suspension periods or restart when the device is removed.
Washington does not send a notification when your SR-22 period ends. You're responsible for tracking your reinstatement date and calculating three years forward. Dropping SR-22 filing even one day early is treated as a lapse and triggers license suspension, a new three-year filing requirement, and potential carrier cancellation. Most carriers will notify you 30–45 days before your filing end date, but you should track it independently.
Once your three-year period ends, contact your carrier and request SR-22 removal. Your rate typically drops $15–$35 monthly immediately — that's the filing fee disappearing. The larger rate reduction happens over the following 12–24 months as the DUI conviction ages out of your carrier's surcharge window. Full standard-risk pricing usually returns 5–6 years post-conviction, though some carriers hold DUI surcharges for up to seven years.
How to Shop for Post-IIL Coverage Without Breaking SR-22 Continuity
Shopping carriers while maintaining SR-22 filing requires coordinating your new policy effective date with your old policy cancellation date. A gap of even one day between policies is reported as an SR-22 lapse to Washington DOL and triggers suspension. Request your new carrier file SR-22 on the same day your new policy starts, and confirm your old carrier cancels SR-22 filing the same day your old policy ends.
Most carriers process SR-22 filing electronically in Washington — it reaches DOL within 24–48 hours. When you bind a new policy, confirm your agent submitted SR-22 filing immediately and request a filing confirmation number. Do not cancel your old policy until you've verified the new SR-22 is on file with DOL. Washington's online driver portal shows active SR-22 filings, usually updated within 2–3 business days.
The best time to shop is 30–45 days before a policy renewal, when you can lock a new rate and coordinate the transition without time pressure. Drivers who wait until their current policy expires or cancels often face lapses because they're rushing the SR-22 transfer. Progressive, GEICO, and The General all offer same-day SR-22 filing in Washington for drivers with one year post-IIL. Comparing quotes from all three at your 12-month mark typically surfaces a $40–$70 monthly rate difference between the highest and lowest offers.
