Your SR-22 filing and ignition interlock device both have required periods — but they rarely end on the same date. Here's how to track both timelines, what happens when one requirement expires before the other, and what you'll pay while both run concurrently.
Do SR-22 and ignition interlock requirements run on the same timeline?
No. SR-22 filing requirements are set by your state DMV or Department of Insurance, typically lasting 3 years from the date your license is reinstated. Ignition interlock device installation periods are ordered by the court or administrative hearing officer, often tied to your conviction date, sentencing date, or the date the device is installed — not your reinstatement date.
In most DUI cases, the ignition interlock period starts when the device is installed and calibrated, which may be weeks or months before your license is reinstated and your SR-22 filing begins. A court may order 12 months of ignition interlock starting from installation, but your DMV requires 3 years of SR-22 starting from reinstatement. You'll finish the ignition interlock requirement 2 years before your SR-22 filing obligation ends.
The two clocks do not sync automatically. You owe both until each clock runs out independently. This means overlapping monthly costs for the duration of the shorter requirement, then solo SR-22 filing costs after the ignition interlock period ends.
What do you pay each month while both requirements are active?
Ignition interlock devices cost $70 to $150 per month for lease, calibration, and monitoring — paid directly to the device provider. SR-22 insurance carries the underlying liability policy premium plus a one-time filing fee of $25 to $50 submitted by your carrier to the state. The monthly premium itself is elevated because SR-22 signals high-risk status to insurers.
A driver with a DUI and SR-22 requirement typically pays $150 to $300 per month for liability insurance alone, compared to $85 to $140 for a clean-record driver in the same state. Add the ignition interlock lease, and total monthly compliance costs run $220 to $450 while both requirements are active. Estimates based on available industry data; individual rates vary by driving history, vehicle, coverage selections, and location.
Once the ignition interlock period ends, you stop paying the device lease but continue paying the elevated SR-22 insurance premium until your filing obligation expires. The SR-22 premium may drop slightly after 12 to 24 months if you maintain continuous coverage and avoid new violations, but most carriers hold high-risk pricing for the full 3-year filing period.

Which requirement typically ends first?
The ignition interlock requirement almost always ends first. Courts typically order 6 to 12 months of ignition interlock for a first DUI, 1 to 2 years for a second offense, and 2 to 3 years for repeat offenders or aggravated circumstances. SR-22 filing periods are set by statute at 3 years in most states, measured from the date your license is reinstated, not from your conviction or sentencing date.
If you installed an ignition interlock device 60 days after your DUI arrest and your license was reinstated 90 days after that, your ignition interlock clock started 30 days before your SR-22 clock. A 12-month ignition interlock order expires 11 months into your SR-22 filing period. You'll owe SR-22 insurance premiums and the associated filing for another 25 months after the device is removed.
The gap between the two expiration dates creates a window where you're still paying high-risk insurance rates but no longer leasing the device. This is the period where most drivers see slight rate reductions if they've maintained continuous coverage and avoided lapses or new violations.
What happens if you remove the ignition interlock device early?
Removing the ignition interlock device before your court-ordered period expires triggers an immediate violation report to the DMV and the court. Most ignition interlock providers are required to notify the state within 48 hours of early removal or tampering. The DMV will suspend your license again, often immediately, and the court may extend your ignition interlock requirement or add jail time for non-compliance.
Your SR-22 insurance does not end when the ignition interlock requirement expires — it continues for the full 3-year filing period regardless of device status. But if your license is suspended for early device removal, your SR-22 filing lapses because you cannot maintain continuous insurance without a valid license. That lapse resets your SR-22 clock to zero in most states. You'll owe the full 3-year filing period again starting from your next reinstatement date.
Never assume the ignition interlock requirement is complete until you receive written confirmation from the court or DMV. Some states require a final calibration report or compliance certificate before officially closing the requirement. Missing that final step can extend your requirement by months.
Can you reduce the cost of either requirement?
You cannot negotiate the ignition interlock lease cost — state-certified providers set fixed monthly fees for installation, calibration, and monitoring. But you can reduce SR-22 insurance premiums by shopping among carriers that write high-risk policies in your state. Not all carriers write SR-22, and those that do price risk differently. Some specialize in DUI cases and offer more competitive rates than general-market carriers.
Carriers writing SR-22 in most states include Progressive, The General, Bristol West, National General, and Acceptance Insurance. Regional carriers and state-assigned risk pools also write SR-22 but typically at higher premiums. Request quotes from at least three carriers before binding coverage. Rate differences for the same SR-22 driver can exceed 40% between the highest and lowest bidder.
Once both requirements are active, maintain continuous coverage and avoid new violations. Most carriers reduce rates slightly after 12 months of claims-free, lapse-free SR-22 filing. The reduction is modest — typically 10 to 15% — but it compounds over the remaining filing period. One lapse or new violation resets your risk profile and eliminates any rate reduction you've earned.
How do you track both timelines accurately?
Request written documentation of both start dates and required durations from the agencies that issued them. Your ignition interlock order comes from the court or administrative hearing officer — the order will state the installation date or the date the clock begins and the total number of months required. Your SR-22 filing period is set by the DMV and documented in your reinstatement letter or compliance notice.
Mark both expiration dates on a calendar you check monthly. Calculate the ignition interlock end date by adding the required months to the installation or start date stated in your court order. Calculate the SR-22 end date by adding 3 years to your license reinstatement date. These dates rarely align.
Two weeks before either requirement expires, contact the issuing agency to confirm you've met all obligations and request written confirmation of completion. Some states require a final compliance report before officially closing the requirement. Missing that final step can extend your requirement by months without notice.
