Almost every state (except New Hampshire and Virginia) requires its licensed drivers to have a minimum amount of insurance coverage. The required insurance generally includes bodily injury liability coverage and property damage liability coverage in certain minimum amounts.

You are required to show proof of the minimum insurance coverage to a police officer when you are stopped for a moving traffic violation or involved in a traffic accident—and you may receive a citation if you are not able to show proof of insurance—also known as failure to maintain financial responsibility (FMFR) or no proof of insurance. And in some states, you are required to show proof of insurance to register your car. In those states, the failure to register your car may result in an additional citation.

But a ticket or citation for no proof of insurance may be correctable—a fix-it ticket of sorts—if the driver did have the required insurance but was unable to provide proof of it when requested by the law enforcement officer. Laws vary from state to state but in that situation the driver may be able to have the ticket dismissed upon showing proof of insurance and possible payment of a smaller fine.

If you have been convicted of DUI/DWI (or a similar offense) or of driving without insurance (failure to maintain financial responsibility) or of reckless or negligent driving, you may be required to get a Financial Responsibility Insurance Certificate (SR-22). An SR-22 is proof or verification the holder is maintaining vehicle liability insurance in the required amounts. It is not a type of insurance—it is a form filed with the state’s department of public safety (DPS), department of transportation (DOT), or department of motor vehicles (DMV) and may also be referred to as an SR-22 Bond or SR-22 Form.

An SR-22 can be issued by most insurance providers, who will notify the state’s department of public safety or department of motor vehicles when an SR-22 is cancelled, terminated, or lapses. There are usually significant additional costs for an insured (driver) to get an SR-22.

The state will often require a driver whose license has been suspended following an arrest for DUI/DWI to provide an SR-22 to get their occupational or restricted license or to have their driver’s license reinstated.

In New Hampshire, unlike most states, drivers are not legally required to carry auto insurance. However, if a driver in New Hampshire chooses not to carry insurance, they must be able to demonstrate financial responsibility in the event of an at-fault accident. If a driver is unable to show proof of financial responsibility, they may face penalties. New Hampshire does require drivers who have been convicted of certain offenses, such as DUI/DWI or driving without insurance, to file an SR-22 form. An SR-22 is not insurance but a certification of financial responsibility that must be maintained for a set period and is filed with the state's Department of Motor Vehicles (DMV). Drivers required to file an SR-22 will often face higher insurance premiums and additional fees from their insurance provider.
