What Is Ignition Interlock Insurance Insurance?
Ignition interlock insurance is a non-standard endorsement designed to offset the financial burden of court-mandated IID installation and monitoring after DUI convictions or restricted license approvals. The device prevents the vehicle from starting unless the driver provides a clean breath sample, and the court typically orders it for 6 to 24 months depending on state law and conviction history. Standard carriers rarely offer this coverage, so drivers usually access it through non-standard insurers like Bristol West, Direct Auto, GAINSCO, or Safe Auto, often bundled with SR-22 filing.
- You are convicted of DUI in Ohio and receive a 12-month IID order as part of your hardship license approval. Installation costs $120, monthly monitoring is $90, and removal is $75. Over 12 months, total out-of-pocket IID expense is $1,395. If you carry ignition interlock insurance with a $250 deductible, the policy covers $1,145 of that total, reducing your burden to $250 plus monthly premiums.
- After a second DUI in Illinois, the court mandates a 24-month IID period and you apply for an occupational license. Device installation is $100, monthly calibration runs $80, and removal is $100. Total cost without coverage is $2,120. With ignition interlock insurance carrying a $500 deductible, you pay $500 upfront and the policy covers the remaining $1,620 across the full compliance period.
- Your California restricted license requires 6 months of IID compliance before full reinstatement. Installation costs $85, monthly fees are $75, and removal is $60. Without coverage, the 6-month total is $655. Your non-standard carrier bundles ignition interlock coverage into your SR-22 policy with no separate deductible, reducing your out-of-pocket cost to zero for device fees and absorbing the $655 total into your premium.
How Much Does Ignition Interlock Insurance Insurance Cost?
Ignition interlock insurance adds $15–$40/month to SR-22 or non-standard auto premiums, translating to $180–$480 annually depending on state, carrier, and device compliance period.
- Length of court-ordered IID compliance period — 6-month orders cost less than 24-month mandates due to lower cumulative exposure.
- Deductible structure — policies with $250 deductibles run $10–$15/month cheaper than zero-deductible endorsements.
- State-mandated IID fee caps — some states regulate monthly calibration fees, which lowers carrier risk and premium.
- Number of vehicles requiring devices — multi-vehicle households face higher premiums if each car needs IID installation.
- Prior IID violations — missed calibrations or failed breath tests raise premiums 20–35% on renewal.

Who Needs Ignition Interlock Insurance Insurance?
Drivers under court-ordered IID mandates as a condition of hardship license, restricted license, or occupational license approval should carry this coverage if they cannot afford $1,000–$2,500 in upfront and monthly device costs. Those with extended compliance periods of 18 months or longer see the clearest return, as premium costs stay flat while out-of-pocket IID fees compound monthly. Drivers transitioning from suspended to restricted licenses who need immediate employment access benefit from bundling this coverage with SR-22 filing to reduce cash-flow strain.
Compare total out-of-pocket IID cost over your compliance period against total premium cost for the same period. If device fees exceed premium plus deductible by $300 or more, the coverage pays off. If your court order is under 6 months and device costs fall below $600, paying cash avoids the administrative burden of filing claims and dealing with non-standard carrier endorsement paperwork.
