Minimum Coverage Requirements in New Hampshire
Your current insurance carrier will not cancel your policy immediately after a DUI or serious violation in New Hampshire — but they will almost certainly non-renew it when your current term expires, giving you 30 to 90 days to find replacement coverage. The New Hampshire Department of Safety typically requires drivers convicted of DUI, driving after suspension, or reckless driving to file an SR-22 certificate proving continuous liability coverage for 3 years. You must secure non-standard auto insurance that offers SR-22 filing before your current policy ends, or you will face an extended license suspension and additional reinstatement fees.
How Much Does Car Insurance Cost in New Hampshire?
After a DUI or serious violation in New Hampshire, expect your premium to increase 50–200% depending on the severity of the offense, your age, and your prior driving record. A senior driver with a clean record before a first-time DUI typically sees monthly premiums rise from $80–$120 to $150–$300 for minimum liability coverage. Full coverage for a financed vehicle can exceed $400/month in the first year after a violation.
What Affects Your Rate
- Violation type: DUI convictions carry the highest rate increases (100–200%), while reckless driving or suspended license violations increase rates 50–100%
- Age and prior record: senior drivers with no prior violations typically see smaller increases than younger drivers with multiple offenses
- Time since violation: rates begin to decrease 3–5 years after the conviction date, with the steepest declines after SR-22 filing ends
- Carrier availability: New Hampshire has fewer non-standard carriers than neighboring Massachusetts, limiting competition and keeping rates higher
- Credit-based insurance score: New Hampshire allows insurers to use credit in underwriting, and a violation combined with poor credit compounds rate increases
- Vehicle value and coverage level: switching from full coverage to liability-only on an older paid-off vehicle can cut premiums by 40–60%
