SR-22 and Ignition Interlock Lookup
Do You Need an SR-22 or Ignition Interlock After a DUI?
Most states require proof of insurance, usually an SR-22 filing (an FR-44 in Florida and Virginia), for a set period after a DUI, and many require an ignition interlock. Pick your state to see its filing, how long it lasts and its interlock rules.
How SR-22 and Interlock Requirements Work
The insurance filing and the interlock are usually conditions of getting your license back. Missing either can restart a suspension. Read how SR-22 insurance works and how ignition interlock programs work, or see hardship licenses that may require an interlock.

Frequently Asked Questions
What Is an SR-22?
An SR-22 is a certificate your insurance company files with the state to prove you carry at least the required liability coverage. It isn't a type of insurance itself. Florida and Virginia use an FR-44 after a DUI, which requires higher coverage.
What Happens if Your SR-22 Lapses?
Your insurer must tell the state, and the state can suspend your license again. Keep the policy active for the whole required period.
Who Pays for an Ignition Interlock?
Usually the driver pays installation and monthly fees, and some states have programs that reduce the cost for people with low incomes. Each state page links its program rules.
