The first thing to understand about an SR-22 is that you cannot buy one. It is not a coverage, not a policy, not a product on a rate sheet. It is a certificate your insurer files with a state agency saying that a qualifying policy is in force, and it exists so the state can be told the moment that stops being true.
Texas makes the point plainly. The statute there never uses the term at all — Transportation Code chapter 601 requires “evidence of financial responsibility,” and the SR-22 is simply the administrative form the Department of Public Safety accepts for it. The form is the state’s plumbing. The insurance is separate, and you pay for it separately.
The second thing to understand is that the plumbing is not standard.
Where it exists, and for how long
| State | Form | Time on file |
|---|---|---|
| Ohio | SR-22 | 1 year |
| Texas | SR-22 | 2 years |
| California | SR 22 | 3 years |
| Florida | SR-22 | 3 years |
| Georgia | SR-22 / SR-22A | 3 years |
| Illinois | SR-22 | 3 years |
| New York | None | — |
| Pennsylvania | None | — |
| North Carolina | DL-123 | 3 years |
| Michigan | Insurer’s certificate (not an SR-22) | 3 years |
Ohio sits alone at one year, and only recently. Until 9 April 2025 the term ran five years for a class A, B or C suspension and three years for a class D, E or F suspension. ORC 4509.45(D) now reads one year from the date the registrar imposes the suspension, for every suspension class — though a non-compliance added to the record before that date keeps the older term. See Ohio’s SR-22 page.
Georgia runs two forms rather than one. The plain SR-22 backs a probationary licence; the SR-22A, used after a second or subsequent no-insurance conviction, requires six months of premium paid in full up front and has to be maintained for three years from the date of conviction. That prepayment is the part people do not expect. See Georgia’s SR-22 page.
Florida’s clock depends on what put you there. A DUI conviction or plea after 1 October 2007 does not merely require a filing — it requires much higher limits, $100,000 per person, $300,000 per crash and $50,000 property damage, carried for a minimum of three years under § 324.023. Proof filed to clear an ordinary no-insurance suspension is maintained for two.
The four states with no SR-22
New York abolished the filing in 1957. Vehicle & Traffic Law § 346 states that on and after 1 February 1957 no person shall be required to file or maintain proof of financial responsibility under the Motor Vehicle Safety Responsibility Act. What replaced it is continuous monitoring: insurers report every policy and every termination electronically to DMV, and DMV acts on the lapse itself — suspending the registration and the licence without any certificate ever changing hands. Guides that list an SR-22 requirement for New York are describing a filing the state ended almost seventy years ago. See New York’s page.
Pennsylvania has none either. PennDOT works from the insurance I.D. card and from the cancellation notices insurers are required to send it. Its regulations list what it accepts as proof: the I.D. card, the policy declaration page, a valid binder, or a signed Pennsylvania Automobile Insurance Plan application. Restoration after a lapse is proof of current insurance plus the fee — $119 to restore the registration, $94 for the licence. See Pennsylvania’s page.
North Carolina uses its own paperwork. Form DL-123 is a certificate of insurance issued by a North Carolina-licensed insurer, and it comes with rules the SR-22 does not have: it must be printed, since a digital image on a phone is not accepted, and it is valid only 30 days from the date it is issued. A driver who owns no registered vehicle signs a DL-123A certification of exemption instead. Separately, insurers file Form FS-1 with NCDMV to clear a registration lapse. The three-year duty comes from G.S. 20-19(k), and letting it drop is grounds for suspending the restored licence for 30 days. See North Carolina’s page.
Michigan does require a certified filing, but it is not an SR-22 and it is not triggered by what triggers one elsewhere. Proof is furnished by the insurance carrier filing a written certificate with the Secretary of State’s Driver Record Activity Unit, or by a bond or a deposit of money or securities; an application for insurance is not accepted. And the trigger is a single item — an unsatisfied court judgment for damages caused while driving uninsured. Alcohol and drug convictions, which put a driver under an SR-22 in most states, do not produce a filing in Michigan at all. See Michigan’s page.
What a lapse does while the filing is live
This is where the certificate earns its keep, because the insurer’s duty runs to the state rather than to you.
In Ohio and Michigan an insurer cannot cancel a certified policy until ten days after it files notice with the state. In Illinois, when an SR-22 lapses the insurer files an SR-26 Cancellation Certificate with the Secretary of State’s Safety and Financial Responsibility Section, and the driving record is suspended on receipt — which is why the state’s advice is to renew at least 45 days before expiry. In Georgia the insurer reports an SR-22A cancellation straight to DDS and the licence is cancelled, with the three-year clock not carrying over.
California states the consequence without softening it: once filed proof stops covering you, DMV must demand new proof and suspend the driving privilege until it is filed. Texas re-suspends the licence and charges $100 to reinstate — a single fee that covers every licence and registration reinstated in connection with the payment.
The practical shape of it
An SR-22 does not make insurance more expensive by itself. It makes it harder to leave, because the state now finds out on the day you stop paying rather than on the day you are stopped.
Where the filing exists, the questions worth answering are how long it runs in that particular state, what the reinstatement fee schedule looks like if it lapses, and whether a repeat triggers a different form. Where it does not exist — New York, Pennsylvania, North Carolina, Michigan — the monitoring has not gone away. It has just moved somewhere you cannot see it.
