Minimum Coverage Requirements in New Hampshire
New Hampshire is the only state that does not require auto insurance for most drivers — but a DUI conviction eliminates that exemption. After a DUI, you must file SR-22 proof of financial responsibility with the New Hampshire Division of Motor Vehicles for 3 years and maintain continuous coverage meeting at least 25/50/25 liability limits. A lapse triggers immediate license re-suspension and restarts the 3-year SR-22 clock. New Hampshire operates under a fault-based liability system, meaning the at-fault driver's insurance pays injury and damage claims.
How Much Does Car Insurance Cost in New Hampshire?
SR-22 insurance premiums in New Hampshire after a DUI typically increase 80% to 140% over standard rates, with average monthly costs ranging from $120 to $215 depending on age, prior history, and coverage level. Non-owner SR-22 policies cost substantially less — $35 to $70 per month — because they carry no collision or comprehensive exposure. Filing fees add $25 to $50 one-time, and many carriers require 6-month policies paid in full upfront for high-risk drivers.
What Affects Your Rate
- New Hampshire's lack of insurance mandate increases uninsured driver rates to approximately 10%, raising UM claim frequency and insurer risk pricing for all drivers.
- DUI conviction date determines SR-22 clock start — not filing date — meaning delayed filing extends your total compliance period beyond 3 years from conviction.
- Second-offense DUI premiums in New Hampshire often exceed $300 per month due to longer suspension periods and mandatory ignition interlock device requirements.
- Manchester and Nashua zip codes typically see 15% to 25% higher SR-22 premiums than rural areas due to accident frequency and theft rates.
- Carriers underwriting high-risk SR-22 in New Hampshire include Progressive, The General, and National General — standard carriers like GEICO and State Farm often non-renew post-DUI policies.
- Non-owner SR-22 policies cost 60% to 75% less than standard SR-22 because they exclude vehicle damage exposure, but most drivers do not know this option exists.

SR-22 Insurance After DUI
SR-22 is a certificate your insurer files with the New Hampshire DMV proving you carry liability insurance. Required for 3 years after a DUI, it costs $25 to $50 to file but raises premiums 80% to 140%. Continuous coverage is mandatory — a single day lapse triggers immediate re-suspension.
Non-Owner SR-22 for Post-DUI Compliance
Non-owner SR-22 provides liability coverage when you do not own a vehicle but need to meet New Hampshire's post-DUI filing requirement. It covers you when driving borrowed or rented cars and costs far less than standard SR-22 because it excludes vehicle damage coverage.
Conditional Restoration Hardship License
New Hampshire's Conditional Restoration allows restricted driving after serving 30 days for a first DUI or 90 days for a second. You must maintain active SR-22 insurance and drive only for approved purposes: work, school, medical care, and court-ordered treatment. Violations revoke the restoration immediately.
Ignition Interlock Device Insurance
Second-offense DUI convictions in New Hampshire require ignition interlock installation for 12 to 24 months. Your SR-22 insurer must be notified of the device and may adjust rates based on compliance data. Installation costs $75 to $150, with monthly monitoring fees of $60 to $90.
Uninsured Motorist Coverage
Uninsured motorist coverage pays your medical bills and lost wages if a driver with no insurance hits you. New Hampshire does not mandate UM, but approximately 10% of drivers carry no coverage. Without UM, your only recourse is suing an uninsured driver, which rarely recovers meaningful damages.
High-Risk Auto Insurance
High-risk auto insurance is coverage written by carriers specializing in DUI, suspension, and SR-22 drivers. These carriers — Progressive, The General, National General, Bristol West — charge higher premiums but accept drivers standard carriers decline or non-renew. Policies often require 6-month prepayment.
