If you're running both an SR-22 filing and an ignition interlock requirement after a DUI, they rarely end on the same date — and most drivers pay for the wrong one longer than they legally have to.
SR-22 and Ignition Interlock Run on Separate Clocks
Your SR-22 filing requirement and ignition interlock device requirement stem from the same DUI conviction, but they're administered by different agencies with separate start dates, durations, and completion criteria. The SR-22 is a financial responsibility filing mandated by your state DMV, typically lasting 3 years from your license reinstatement date. The ignition interlock requirement is a court-ordered or DMV-ordered condition tied to your driving privileges, often lasting 6 months to 2 years depending on your state and offense severity.
These clocks don't start simultaneously. Your interlock period usually begins the day the device is installed and calibrated, which might be weeks or months before you reinstate your license and file SR-22. Your SR-22 clock starts the day your insurer files the certificate with the DMV, which happens only after you've purchased a policy that meets state minimums. If you delay reinstatement, your interlock clock runs while your SR-22 clock hasn't started.
Most drivers assume both requirements end together because they originated from the same conviction. They don't. The interlock typically ends first — you'll receive a court or DMV notice authorizing removal once you've completed your monitored period with no violations. Your SR-22 obligation continues until your full filing period elapses, regardless of interlock completion. Mixing these timelines costs you money: either you're paying interlock lease fees after the legal requirement ended, or you're maintaining SR-22 coverage after your filing obligation expired because no one told you to stop.
What You Pay Each Month While Both Requirements Are Active
When both SR-22 and ignition interlock are running concurrently, you're paying three separate monthly costs. First, your SR-22 non-standard auto insurance premium, which typically runs $150–$280 per month depending on your state, violation severity, and coverage limits. Second, your ignition interlock device lease fee, which averages $70–$150 per month including installation, calibration appointments, and monitoring. Third, any restricted license or reinstatement fees your state assesses, though these are usually one-time payments rather than monthly recurring charges.
Your insurance premium doesn't drop just because you have an interlock device installed. Some carriers offer a modest discount — 5% to 10% — if you voluntarily install an interlock as a risk mitigation signal, but this discount is rare among non-standard carriers writing post-DUI policies, and it doesn't offset the device lease cost. The SR-22 filing itself adds $15–$50 to your total premium annually, but the real cost driver is the DUI conviction on your record, which elevates you into high-risk tier pricing regardless of the interlock.
Carriers writing SR-22 with active interlock requirements include Progressive, The General, Bristol West, and Gainsco in most states. National carriers like State Farm and Allstate rarely write new policies for drivers with both an active SR-22 requirement and a mandated interlock device — they'll keep existing customers in some states but route new business to non-standard subsidiaries. This means you're shopping a smaller carrier pool, and competition for your business is limited, which keeps monthly premiums elevated even after your interlock period ends.

Which Requirement Ends First and How You Know
In most DUI cases, your ignition interlock requirement ends 12 to 18 months before your SR-22 filing obligation expires. A first-offense DUI typically triggers a 6-month to 1-year interlock requirement and a 3-year SR-22 filing period. A second offense often mandates 1 to 2 years of interlock and 3 to 5 years of SR-22, depending on your state. The interlock clock runs from device installation; the SR-22 clock runs from your license reinstatement date, which is often months later.
You'll know your interlock requirement is ending when you receive written notice from your DMV or the court that issued the order. This notice authorizes you to have the device removed by a certified installer — do not remove it yourself or have an uncertified shop do it, as that can trigger a violation and restart your monitoring period. Once removed, you must return to the DMV with proof of completion — usually a certificate from the interlock provider showing you completed your full term with no failed tests or tampering incidents.
Your SR-22 filing ends only when your state-mandated period elapses with no lapses in coverage. Your insurer does not automatically notify you when this happens. You must track the end date yourself — it's three years from your reinstatement date in most states, or the specific period stated in your reinstatement letter. After that date passes, contact your insurer and request SR-22 removal from your policy. If you've moved to a standard carrier by then, confirm with your new carrier that no SR-22 is on file. Some DMVs send a closure notice; most don't. The absence of a notice doesn't mean the requirement is still active.
What Happens If You Stop Paying for One Before the Requirement Ends
If you stop paying your interlock lease before your court-ordered or DMV-ordered period ends, the device provider reports the deactivation to the DMV within 24 to 48 hours. Your state treats this as a violation of your restricted license terms and immediately suspends your driving privileges. You'll receive a suspension notice requiring you to reinstall the device, complete the remaining term, and often restart your monitoring period from zero. Some states add 6 months to your original requirement as a penalty for early removal.
If you let your SR-22 insurance lapse — even for one day — your carrier is legally required to notify the DMV electronically, usually within 24 hours. Your license is suspended automatically, and your SR-22 filing clock resets to zero in most states. Reinstatement requires you to purchase a new SR-22 policy, pay reinstatement fees, and restart your full 3-year filing period from the new reinstatement date. This is the most expensive mistake post-DUI drivers make: a single missed payment can add $5,000 to $8,000 in additional premiums and fees over the extended filing period.
Some drivers assume that once the interlock is removed, they can drop to liability-only coverage or switch to a cheaper carrier without SR-22 capability. If your SR-22 requirement is still active, switching to a carrier that doesn't file SR-22 triggers an immediate lapse notice to the DMV. Before you shop for new coverage, confirm your SR-22 end date in writing from the DMV. If the requirement is still active, your new carrier must file SR-22 before your old policy cancels, with zero gap in coverage.
How to Transition Out of Both Requirements Without Triggering a Violation
When your interlock requirement ends, schedule your removal appointment with a certified installer and request a completion certificate the same day. Take that certificate to your DMV within 10 business days — some states require this step before they lift your restricted license status, even if you've completed your monitored period. Do not assume the interlock provider notifies the DMV of your successful completion; in most states, you must close the loop yourself.
Once your interlock is removed and your restricted license status is lifted, your SR-22 requirement continues unchanged. Your insurance rate won't drop immediately just because the device is gone — your carrier prices your policy based on your violation history and filing requirement, not the presence of the interlock. However, this is the right time to request a policy review and confirm whether your carrier offers any post-interlock discount or whether you now qualify for a lower-tier product within their non-standard lineup.
When your SR-22 filing period ends, contact your insurer and request removal of the SR-22 filing from your policy. Some carriers automatically remove it; most don't. If you're still with a non-standard carrier at this point, shop for standard coverage — your violation is aging off, and you're now eligible for competitive quotes from carriers that wouldn't write you during your filing period. Gather your completion certificate from your interlock provider, your SR-22 removal confirmation from your insurer, and a copy of your current driving record showing no active suspensions. These documents prove to new carriers that your high-risk period is over.
Which Carriers Write Coverage During Overlapping Requirements
Carriers willing to write SR-22 policies for drivers with active ignition interlock requirements are a smaller subset of the already-limited non-standard market. Progressive writes this coverage in most states through its non-standard division, but rates are significantly higher than their standard-tier products. The General actively writes interlock-required policies and often provides the most competitive quote for drivers in this situation, particularly in states with high DUI volumes like Arizona, California, and Florida.
Bristol West and Gainsco write overlapping SR-22 and interlock coverage in select states, typically where state law mandates interlock for all DUI offenses. National carriers like State Farm, Allstate, and Farmers rarely write new policies for drivers with both requirements active — if you held a policy with them before your DUI, they may allow you to add SR-22 and continue coverage, but new applicants are routed to non-standard markets. GEICO writes some interlock-required policies but declines coverage in states where interlock violations carry additional penalties.
Comparing quotes from at least three carriers during this period is essential. Rate variation for SR-22 with active interlock can exceed 40% between carriers writing the same driver profile. Some carriers price the interlock as an additional risk signal and load your premium accordingly; others view it as a mitigating factor showing compliance and price it neutrally. Your state's fault system, your age, and your vehicle type also influence which carrier offers the lowest rate, so filtering by brand reputation or national presence won't reliably get you the best price.
