What Is an SR-22 and Who Needs One?

Key takeaways

An SR-22 is a certificate your insurer files with the state. It is a filing, not a type of insurance.
States generally require it after certain violations or when you could not show proof of insurance.
How long it stays on file depends on the state and the reason, from 180 days to three years in our examples.
Ask your state's agency exactly which form it requires and for how long.

What an SR-22 is

An SR-22 is a certificate that your insurer files with the state to prove you carry at least the minimum required liability coverage. It is a filing, not a separate kind of insurance.

The Wyoming Department of Transportation, for example, describes it as a filing from an insurer authorized in Wyoming that tells the Department you have a policy meeting the minimum limits.

When a state may ask for one

States generally require it after certain violations or after you could not show proof of insurance. These examples come from the official sources in our state summaries:

Nebraska: if you could not produce proof of insurance when asked and were not insured on the date of the citation, you must file proof of financial responsibility, normally an SR-22.
Indiana: after a suspension for failing to provide proof, the BMV requires your insurer to file an SR22 and keep it in place for 180 days, according to its driver manual.
North Dakota: certain violations, including driving without insurance, can lead to suspension or revocation, followed by a requirement to show proof of future financial responsibility for one year.
Vermont: people required to file financial responsibility insurance must keep it on file for a minimum of three years, and the DMV accepts only an SR-22 certificate from an insurer.
Wyoming: after an accident without proof of insurance, the Department asks for an SR-21 verifying coverage, or security, or a conditional release of liability, and may require an SR-22.

How long it can stay on file

The length is set by the state and by the reason it was required. The examples above range from 180 days in Indiana to three years in Nebraska and Vermont. Your state's agency can tell you the exact period for your case.

If you are told you need one

Ask the agency, usually the DMV, exactly which form it requires and for how long.
Ask your insurer whether it files SR-22 forms in your state.
Keep your policy active for the whole required period, and ask the agency what happens if it lapses.
Keep copies of everything the agency and your insurer send you.

Common mistakes

Treating an SR-22 as a replacement for car insurance. You still need a liability policy.
Letting your policy lapse during the required period.
Assuming your old state's requirement applies unchanged after you move.

Questions

Is an SR-22 the same as car insurance?

No. It is a certificate filed by your insurer to prove you carry the required coverage. You still need an auto liability policy.

Do all states use SR-22 forms?

Not every state uses this form, and some use a different form or name. Ask your state's motor vehicle agency which proof it requires.

Does an SR-22 follow me if I move to another state?

Requirements are set state by state. If you move, ask both your old and your new state's agencies what proof is needed.
