What Is Ignition Interlock Insurance Insurance?

Ignition interlock insurance isn't a separate coverage type—it's standard auto liability insurance paired with an SR-22 certificate of financial responsibility filing. The SR-22 proves to your state that you carry continuous coverage while your occupational license restricts you to vehicles equipped with an ignition interlock device. If your policy lapses for even one day, your insurer notifies the state immediately, triggering occupational license suspension and forcing you to restart your SR-22 filing period from day one in most cases.

Who Needs Ignition Interlock Insurance Insurance?

You need ignition interlock insurance if you're applying for or currently hold an occupational license in Pennsylvania, Texas, or Wisconsin after a DUI/DWI/OWI conviction. All three states mandate continuous SR-22 coverage for the entire period your occupational license is active—typically 2-3 years—and require proof of filing before your license is issued. If you drive for work, school, medical appointments, or household duties under occupational license restrictions, this coverage is legally mandatory, not optional.

Check your court order or DMV notice for the exact SR-22 duration—it's printed as a specific end date or a filing period measured from conviction date, not license issuance date. If your occupational license is active, SR-22 coverage is mandatory.
