Minimum Coverage Requirements in New Hampshire
New Hampshire operates under a tort-based liability system and requires all drivers to carry proof of financial responsibility after a DUI conviction or license suspension. The New Hampshire Department of Safety mandates SR-22 filing, which is a certificate your insurer files directly with the state to verify continuous coverage. New Hampshire also enforces strict reinstatement timelines — miss a payment and your insurer cancels the SR-22 immediately, restarting your filing period.
How Much Does Car Insurance Cost in New Hampshire?
New Hampshire SR-22 rates after DUI conviction run significantly higher than standard auto insurance because most mainstream carriers non-renew DUI policies at term, forcing drivers into the non-standard market. Rate increases depend on conviction class — first-offense standard DUI, aggravated DUI with high BAC or injury, and repeat-offense DUI each trigger different underwriting tiers and filing-period lengths.
What Affects Your Rate
- Conviction class drives filing period and premium — first-offense standard DUI typically requires 3-year SR-22 with rates 80–120% above pre-conviction premiums, while aggravated DUI or repeat-offense conviction can double that increase.
- Non-standard carrier availability in New Hampshire varies by county — rural areas outside Manchester and Nashua may have fewer carriers willing to write new SR-22 policies, limiting rate competition.
- Interlock device requirement for aggravated DUI or high BAC adds $70–$100/mo installation and monitoring cost, which insurers treat as a premium modifier for the first 12–18 months of the policy.
- Age and experience interact with DUI conviction — drivers under 25 with first-offense DUI pay $220–$280/mo even at state minimums, as they combine two high-risk underwriting categories.
- Credit score directly impacts non-standard SR-22 rates in New Hampshire — poor credit combined with DUI conviction can raise premiums 40–60% above good-credit rates at the same coverage level.
- Multi-policy bundling is rarely available in the non-standard market — most carriers that write SR-22 after DUI do not offer homeowners or renters policies, eliminating the discount most standard-market drivers receive.

Coverage Types
SR-22 Insurance
SR-22 is a certificate your insurer files with the New Hampshire Department of Safety proving you carry continuous liability coverage. The filing itself costs $25–$50, but the underlying insurance premium increases 80–150% after DUI conviction.
Non-Owner SR-22
Non-owner SR-22 policies provide liability coverage and SR-22 filing for drivers who do not own a vehicle but need to meet New Hampshire's post-DUI filing requirement. This applies to drivers using public transit, rideshare, or borrowing vehicles.
Liability Insurance
Liability insurance pays damage you cause to others in an at-fault accident. New Hampshire requires 25/50/25 minimums, but these limits are exhausted quickly in serious accidents — raising limits to 100/300/50 costs $20–$40/mo more and protects your wages and assets.
Uninsured Motorist Coverage
Uninsured motorist coverage pays your medical bills and vehicle damage when an at-fault driver has no insurance or insufficient coverage. New Hampshire insurers must offer this at policy inception — if you do not reject it in writing, it is added automatically.
Full Coverage
Full coverage combines liability, collision, and comprehensive insurance with SR-22 filing. Required if you finance or lease your vehicle, and protects your own car after an at-fault accident, theft, weather damage, or vandalism.
