Minimum Coverage Requirements in New Hampshire
New Hampshire does not mandate auto insurance for all drivers, making it one of only two states without a universal coverage requirement. However, drivers who cause accidents, receive DUI convictions, commit serious violations, or fail financial responsibility tests must obtain liability coverage and typically file SR-22 proof with the New Hampshire Division of Motor Vehicles. Minimum liability when required is 25/50/25: $25,000 bodily injury per person, $50,000 bodily injury per accident, and $25,000 property damage. High-risk drivers often need coverage above these minimums to avoid gaps if sued beyond policy limits.
How Much Does Car Insurance Cost in New Hampshire?
High-risk insurance premiums in New Hampshire depend heavily on violation type, prior coverage history, and whether you're reinstating from a suspension. A first-offense DUI typically increases rates by 80–120%, while multiple violations or lapses exceeding 6 months can triple premiums. Rates decrease 10–20% per year if you maintain violation-free coverage, with most drivers returning to standard pricing within 3–5 years.
What Affects Your Rate
- Violation type: DUI convictions increase rates 80–150%, while at-fault accidents add 40–80%
- Coverage lapse duration: gaps exceeding 90 days add 20–40% to premiums
- SR-22 filing duration remaining: rates drop 10–15% annually as filing period nears completion
- Non-standard carrier competition: New Hampshire has fewer high-risk insurers than neighboring states, limiting price competition
- Credit score impact: high-risk drivers with poor credit pay 30–60% more than those with good credit in New Hampshire
- Vehicle age and value: older vehicles eligible for liability-only coverage cost 40–60% less to insure than financed newer models requiring full coverage
