What Is Liability Insurance Insurance?
Liability insurance pays for damage and injuries you cause to other people in an at-fault accident. It has two components: bodily injury liability covers medical bills, lost wages, and legal defense if the other driver sues you; property damage liability covers repairs to their vehicle, fence, building, or other property you hit. Your own injuries and vehicle damage are not covered — liability only pays out to third parties you harm.
- You're texting and rear-end the car in front of you at a red light. The other driver has $18,000 in medical bills and $6,500 in vehicle damage. Your bodily injury liability pays the $18,000 medical claim. Your property damage liability pays the $6,500 repair bill. Your own vehicle damage is not covered — you need collision coverage for that.
- You lose control on ice and hit two vehicles. Driver one has $32,000 in injuries; driver two has $15,000. Your per-person limit is $25,000, so driver one receives $25,000 and the remaining $7,000 comes from your own assets unless you carry higher limits. Your per-accident limit is $50,000, which covers both drivers' combined $47,000 in medical costs, but you're personally liable for the $7,000 gap on driver one's claim.
- You back into a parked car in a grocery store lot, causing $3,200 in damage to their bumper and taillight. Your property damage liability pays the $3,200 repair bill in full. If you also damaged your own vehicle backing up, that repair cost is your responsibility unless you carry collision coverage.
Who Needs Liability Insurance Insurance?
You should carry liability insurance if you cannot afford to pay $50,000 or more out of pocket after an at-fault accident, if you finance or lease your vehicle (lenders require it), or if you've been convicted of certain violations and are required to file proof of financial responsibility. Even though New Hampshire doesn't mandate it for most drivers, one serious accident can result in wage garnishment, asset seizure, and license suspension if you can't cover the other party's costs.
Calculate what you could pay tomorrow if you caused $60,000 in injuries and property damage. If that amount would force you to liquidate retirement accounts, take loans, or face wage garnishment, carry liability coverage. If you have accessible assets well above $100,000 and no lender requiring coverage, you can legally skip it in New Hampshire — but one lawsuit will cost more than a decade of premiums.
How Much Does Liability Insurance Insurance Cost?
New Hampshire liability-only policies typically cost $45–$85 per month, or $540–$1,020 annually, for state minimum limits. Higher limits — such as $100,000/$300,000/$100,000 — add $15–$35 per month.
- Your violation history — a DUI or at-fault accident in the past three years can double liability premiums.
- Your age and driving experience — drivers under 25 and over 70 pay 20–40% more due to higher claim frequency.
- The limits you choose — doubling your bodily injury limit from $25,000 to $50,000 per person typically adds $8–$15 per month.
- Your location within New Hampshire — urban areas like Manchester and Nashua have higher rates due to accident density; rural towns cost 10–25% less.
- Your credit-based insurance score — New Hampshire allows insurers to use credit history, and poor credit can increase liability premiums by 30–60%.
- Whether you're required to carry coverage post-violation — drivers filing SR-22 or similar proof after a suspension pay 40–80% more than voluntary buyers.
