New Hampshire law requires people convicted of driving while intoxicated (DWI) to meet certain conditions. One of them is to maintain a New Hampshire SR-22 Insurance Certificate.
According to the New Hampshire Department of Safety, An SR-22 Insurance Certificate proves that the person holding it has liability insurance in case of a car accident. If you are convicted of DWI, you must maintain your SR-22 for three years. For a second DWI conviction, the SR-22 must be maintained for five years.
When you receive your SR-22, examine it closely. You can get an SR-22 in either one of two forms: an “Owner” certificate or a “Non-Owner” certificate. Under New Hampshire law, an Owner certificate must state that your insurance covers “Any Vehicles Owned by the Insured.” It should not list the vehicles you own. A Non-Owner certificate should state that your insurance covers “Any Vehicles Driven by the Insured.”
