SR-22 + Ignition Interlock: Real Monthly Costs to Expect

The combined monthly cost of SR-22 insurance with an ignition interlock device typically runs $250–$450 for most drivers with a DUI conviction. That breaks down to $150–$300 for high-risk auto insurance premiums, $70–$100 for ignition interlock device rental and monitoring, and $15–$50 for SR-22 filing fees amortized monthly. Most drivers expect the SR-22 filing to be expensive — it's not, typically $15–$50 one-time or annual. The sticker shock comes from the insurance premium increase after a DUI, which averages 70–130% above your previous rate. The ignition interlock device is a fixed monthly rental on top of that, billed separately by the device provider, not your insurer. Carriers write SR-22 policies differently than standard auto insurance. Many national brands route high-risk business to specialty subsidiaries or non-standard divisions that price and underwrite separately. Your quote from the same carrier you had before your DUI may be declined or routed to a different entity entirely.

SR-22 filing periods range from 1–5 years depending on your state and conviction, with 3 years being most common for first-offense DUI. Ignition interlock requirements are set by court order or DMV administrative action, typically 6 months to 3 years. The two timelines do not always align. In many states, you can petition to remove the ignition interlock after meeting minimum compliance thresholds — typically 6–12 months of violation-free monitoring. Your SR-22 requirement continues independently. You're still paying the elevated insurance premium after the device is removed, but you eliminate the $70–$100 monthly device cost. Letting your SR-22 lapse even one day during the required filing period resets your clock to zero in most states. Your insurer is required to notify the DMV immediately when coverage lapses. Your license is suspended again, often without additional notice, and you start the filing period over from the beginning.

Ignition interlock providers charge installation fees upfront, typically $70–$150, then bill monthly rental and monitoring separately. Calibration appointments are required every 30–60 days at $50–$80 per visit, and some providers bundle calibration into the monthly rate while others bill it separately. If you fail a breath test or miss a rolling retest while driving, most devices trigger a lockout countdown and require an unscheduled service appointment to reset. Service call fees run $50–$100 and are not covered by your monthly rental. Some court orders require you to submit printed violation reports at each hearing — providers charge $10–$25 per printed log. SR-22 insurance policies often require higher liability limits than your state's minimum, not because SR-22 raises the legal floor, but because non-standard carriers price high-risk policies with built-in coverage floors. You may be quoted $100,000/$300,000 bodily injury liability when your state only mandates $25,000/$50,000. The carrier is managing their own risk exposure by refusing to write state-minimum policies for DUI violators.

Not all carriers that write SR-22 will insure a driver with an active ignition interlock requirement. Progressive, The General, and National General are among the most consistent writers for this profile. GEICO routes most SR-22 business through their non-standard division or declines it outright in some states. Some regional and specialty carriers — Bristol West, Dairyland, Acceptance — focus exclusively on high-risk drivers and price competitively for DUI violations with device requirements. They typically offer monthly payment plans with no down payment financing, which spreads the cost but adds interest charges of 15–25% APR. Your previous carrier may quote you, but the policy will be underwritten and priced by a different entity. State Farm routes high-risk to their non-standard affiliate in most states. Allstate may decline you entirely or offer coverage at 2–3x your previous premium. The brand name you recognize is not always the entity writing the policy.

Your premium drops most significantly at the 3-year mark post-conviction, when the DUI moves from recent major violation status to older incident in most carrier underwriting models. If your SR-22 filing period is 3 years, you'll see rate decreases starting the policy term after your filing obligation ends. Once the ignition interlock is removed, you eliminate $70–$100 in monthly device costs immediately. Your insurance premium does not drop when the device is removed — the premium is tied to your conviction and filing requirement, not the device. Some drivers assume removing the interlock triggers a rate reduction. It does not. Maintaining continuous coverage without lapses during your filing period signals compliance to future underwriters. Drivers who complete their SR-22 period with no lapses, no additional violations, and no claims often see premium reductions of 30–50% when they transition back to standard-market carriers. One lapse resets that timeline and extends the high-risk pricing window by years.

Get quotes from at least three carriers that write SR-22 for drivers with ignition interlock requirements. Rates vary by 40–70% between carriers for the same profile. Use a high-risk specialist or aggregator that works with non-standard writers — most comparison tools route you to standard-market brands that will decline you. Confirm your state-specific SR-22 filing period and ignition interlock compliance window before you start shopping. Court orders and DMV actions vary, and some states allow early removal of the device with proof of compliance. Knowing your timeline lets you budget the total cost accurately. Pay your policy in full every term if possible. Monthly payment plans on non-standard policies carry APR charges of 15–25%, adding $30–$60 to your annual cost. If you cannot pay in full, confirm the financing terms in writing before binding coverage. Some carriers bury the interest rate in the payment schedule.
