Why Your Premium Changed After the Accident
Your carrier raised your premium because the accident changed your risk profile in their actuarial model. In New Hampshire, where most drivers choose coverage voluntarily rather than under mandate, the rate increase depends on three factors: whether you were determined at fault, the size of the claim your carrier paid, and whether the accident triggered a violation that now requires you to carry coverage. An at-fault accident with a bodily-injury claim typically produces a larger surcharge than a property-damage-only claim, and the surcharge persists for three to five years depending on the carrier.
The confusion comes from New Hampshire's financial-responsibility framework. If you were carrying coverage voluntarily before the accident, the rate increase is a standard underwriting adjustment. If the accident produced a conviction that now requires you to prove financial responsibility, you face both the surcharge and a mandatory coverage period with SR-22 filing. The two paths produce different cost structures, and most households don't know which one applies until the renewal notice arrives.

$25,000 / $50,000 / $25,000
New Hampshire does not require all drivers to carry liability insurance, but drivers who choose or are required to carry coverage must meet these minimum limits: $25,000 bodily injury per person, $50,000 bodily injury per accident, $25,000 property damage. An at-fault accident claim that exceeds these limits can trigger personal liability for the difference.

How Fault Determination Controls the Rate Change
New Hampshire carriers assign surcharges based on fault as determined by the claim investigation, not the police report alone. If you were found at fault and your carrier paid a claim, the surcharge applies at your next renewal and remains on your policy for the carrier's lookback period, typically three to five years. If you were not at fault and filed a claim under your own collision or uninsured-motorist coverage, some carriers apply a smaller surcharge or none at all, but this varies by carrier underwriting rules.
The size of the claim matters. Carriers model future risk based on claim severity, and a bodily-injury payout signals higher expected future costs. If the accident involved injuries and your carrier paid medical claims, expect the surcharge to reflect that exposure.
If the accident produced a conviction for leaving the scene, reckless operation, or DWI, New Hampshire law requires you to file an SR-22 certificate and maintain continuous coverage for three years. The SR-22 filing itself does not increase your premium, but the violation does, and the mandatory coverage period means you cannot drop coverage to avoid the surcharge. The violation surcharge stacks on top of the at-fault accident surcharge, and both persist through the three-year filing period.
An at-fault accident with a bodily-injury claim typically triggers a surcharge that lasts three to five years, and if the accident produced a conviction requiring SR-22 filing, you cannot drop coverage to escape the increase.
What Happens at Renewal After an At-Fault Claim
The surcharge is not a flat dollar amount. It is a multiplier applied to your base rate, so if your base premium was already high due to vehicle type, location, or coverage limits, the percentage increase produces a larger dollar change. Carriers in New Hampshire apply surcharges according to their filed rating plans, and the percentage varies by carrier and claim severity.
The surcharge persists for the carrier's lookback period regardless of whether you file another claim. Most carriers use a three-year or five-year window, meaning the accident affects your rate at every renewal until it ages out of the lookback. If you switch carriers during that period, the new carrier will see the accident on your claims history report and apply their own surcharge. Shopping carriers after an at-fault accident rarely eliminates the increase, but it can reduce the total premium if another carrier's base rate is lower or their surcharge percentage is smaller.

How Long the Surcharge Lasts and When It Drops Off
The surcharge remains on your policy for the carrier's lookback period, which is stated in the carrier's underwriting guidelines and typically ranges from three to five years from the accident date. After the lookback period expires, the accident no longer appears in the carrier's rating calculation, and your premium drops to reflect the removal of the surcharge. The lookback period is not the same as the SR-22 filing period; if the accident required SR-22 filing, the three-year filing requirement and the surcharge lookback period run independently.
If you were found at fault for an accident that did not produce a violation, the surcharge expires when the lookback period ends, and you are not required to maintain coverage after that point unless you choose to. If the accident produced a conviction requiring SR-22 filing, you must maintain continuous coverage for the full three-year filing period, and the surcharge persists for the carrier's lookback period, which may extend beyond the filing requirement. Dropping coverage during the SR-22 period triggers a filing lapse, which restarts the three-year clock and produces an additional suspension.
Some carriers offer accident-forgiveness programs that waive the first at-fault accident surcharge if you meet eligibility criteria, typically a clean driving record for a specified period before the accident. If your policy included accident forgiveness and the accident was your first chargeable claim, confirm with your carrier whether the forgiveness applied. If it did, the surcharge may not appear at renewal. If your policy did not include forgiveness, the surcharge applies according to the carrier's standard rating plan.
NH SR-22 Filing Period After Conviction
3 years
New Hampshire requires SR-22 filing for three years after convictions for DWI, leaving the scene of an accident, or a second reckless-operation offense. The filing period begins on the conviction date, not the accident date, and a lapse in coverage during the period restarts the three-year requirement.

Whether Switching Carriers Reduces the Increase
Switching carriers after an at-fault accident does not erase the surcharge, but it can reduce your total premium if another carrier's base rate or surcharge percentage is lower. Every carrier in New Hampshire pulls your claims history from the same industry databases, so the accident appears on every quote you request during the lookback period. The difference is how each carrier weights the accident in their rating algorithm. A carrier that specializes in non-standard or post-accident coverage may apply a smaller surcharge than a preferred-tier carrier, and their base rate may be structured to absorb higher-risk drivers more efficiently.
If the accident required SR-22 filing, your carrier options narrow to those that write SR-22 policies in New Hampshire. Fifteen carriers in the state write SR-22 coverage, including Geico, Progressive, State Farm, Farmers, National General, The General, Bristol West, and USAA. Not all carriers write SR-22 for all violation types, so confirm SR-22 availability before switching. If you were carrying coverage voluntarily and the accident did not produce a filing requirement, you have access to the full carrier roster, and shopping multiple carriers is the most reliable way to find the lowest post-accident premium.
Compare Carriers That Write Post-Accident Coverage in New Hampshire
The rate increase after an at-fault accident is not uniform across carriers. Base rates, surcharge percentages, and lookback periods vary, and the only way to identify the lowest total premium is to compare quotes from multiple carriers that write your risk profile. If the accident did not require SR-22 filing, request quotes from standard and non-standard carriers. If the accident triggered an SR-22 requirement, request quotes only from carriers confirmed to write SR-22 in New Hampshire, and verify that each quote includes the SR-22 filing fee and the three-year continuous-coverage requirement.
Use the comparison tool to request quotes from carriers writing in New Hampshire. Enter the accident details, the conviction if applicable, and your current coverage limits. The tool routes your request to carriers that write post-accident and SR-22 policies, and you receive quotes that reflect the surcharge and any filing requirements. Compare the total premium, the surcharge amount, and the lookback period each carrier applies, and confirm that the policy meets New Hampshire's minimum liability limits and any court-ordered coverage requirements tied to the conviction.
