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.
Who Needs Ignition Interlock Insurance Insurance?
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.
How Much Does Ignition Interlock Insurance Insurance Cost?
- Length of court-ordered IID compliance period — 6-month orders cost less than 24-month mandates due to lower cumulative exposure.
- 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.
