Uninsured Motorist Coverage in New Hampshire: A Comprehensive Guide

New Hampshire is famously unique: it is the only state in the U.S. that does not mandate auto insurance for most drivers. However, “Live Free or Die” doesn’t mean “Live Free of Responsibility.” Under the state’s Financial Responsibility Laws, if you cause an accident, you are still legally and financially liable for all damages.

Because of this, many New Hampshire drivers choose to purchase insurance voluntarily. In 2026, the state remains a high-risk environment because you are statistically more likely to encounter an uninsured driver here than in almost any other state. If you choose to buy a policy, New Hampshire law requires that it includes Uninsured Motorist (UM) and Medical Payments (MedPay) coverage.

What This Service Includes

In New Hampshire, if you opt for auto insurance, your policy must include several layers of protection to ensure you aren’t left paying for someone else’s lack of coverage.

What is typically included

• Uninsured/Underinsured Bodily Injury (UM/UIMBI): This is mandatory if you buy a policy. It covers your medical bills, lost wages, and pain and suffering if you’re hit by someone with no insurance or insufficient limits.
• Matching Limits: By law (RSA 264:15), your UM limits must equal your liability limits. If you buy $100,000 in liability to protect others, you automatically get $100,000 in UM to protect yourself.
• Medical Payments (MedPay): Every policy must include at least $1,000 in MedPay. This pays for your immediate medical costs regardless of who was at fault.
• Hit-and-Run Protection: UM coverage in New Hampshire specifically includes “phantom” or unidentified drivers who flee the scene.
• Pedestrian Coverage: Your UM and MedPay coverage typically follow you, protecting you and your household members if you are struck while walking or cycling.

What is usually extra or not included

• Uninsured Motorist Property Damage (UMPD): While some states bundle this, in New Hampshire, you generally need Collision coverage to fix your vehicle if an uninsured driver hits you.
• Excess MedPay: While $1,000 is the minimum, it is rarely enough for a modern ER visit. Most drivers opt for $5,000 or $10,000.
• SR-22 Filing: If you have certain convictions (like a DWI), the state will move you from “optional” to “mandatory” insurance status, requiring a special SR-22 filing for three years.

Average Cost Overview

New Hampshire remains one of the most affordable states for auto insurance in 2026, ranking among the top five cheapest states nationally.

What Drives the Range

Prices are highest in urban hubs like Manchester (averaging $102/month for full coverage) and Nashua, while drivers in Concord or rural Lebanon enjoy the lowest rates in the state. In 2026, The Hanover and Progressive have been noted for offering the most competitive “minimum” rates for New Hampshire residents.

Key Cost Factors

• Legislative Update (HB 1568): As of early 2026, the New Hampshire legislature is debating HB 1568, which would end the “optional” insurance era and make liability coverage mandatory for all registered vehicles starting January 1, 2027.
• Stacking (The “Multiple Car” Bonus): New Hampshire allows stacking. If you insure two cars, you may be able to “stack” their UM limits together to double your protection for a single accident—but only if your policy doesn’t explicitly (and clearly) prohibit it.
• Credit Score Influence: New Hampshire allows insurers to use credit-based insurance scores. Drivers with poor credit can pay nearly $150 more per month than those with good credit for the same UM protection.
• Zero-Deductible MedPay: Because MedPay is mandatory and has no deductible, it acts as a “buffer” for your health insurance deductible after a crash.
• Gender and Age: Young male drivers in New Hampshire still face the highest premiums, often paying 2-3 times more than female drivers of the same age.

Ways to Save Money Without Cutting Corners

• Take Advantage of the “Clean Record” Discount: In New Hampshire, a clean driving record can save you over 50% compared to a driver with just one at-fault accident.
• Shop Regional Carriers: Local companies like Farmers Mutual or The Hanover often have more nuanced pricing for New Hampshire’s rural routes than national “big-box” insurers. Use autoinsuranceplans.com to find them.
• Increase Your Collision Deductible: Since New Hampshire doesn’t require insurance, many people skip collision entirely on older cars. If you keep it, moving to a $1,000 deductible can cut your “full coverage” premium by 20%.
• Coordinate MedPay: If you have excellent health insurance, you can keep your MedPay at the $1,000 minimum to save a few dollars.

Common Mistakes and Red Flags

• The “I Don’t Need Insurance” Myth: Not being required to have insurance is not the same as not being liable. If you are uninsured and at fault, the state can suspend your license and registration until you pay for the damages in full or file an SR-22.
• Rejecting Stacking Without Realizing It: Many “budget” policies include anti-stacking language in the fine print. If you have multiple cars, you might be losing out on significant injury protection for a very small monthly saving.
• Underestimating Hit-and-Run Requirements: To use your UM coverage for a hit-and-run, you must report it to the police immediately. Insurers may deny claims for “phantom vehicles” without a formal report.
• Assuming UM Fixes the Car: UM in New Hampshire is for injuries. If an uninsured driver hits your car, you need Collision coverage or you will have to pay for the repairs out of pocket.

Frequently Asked Questions (FAQ)

Is auto insurance mandatory in New Hampshire?

No, for most drivers it is optional. However, if you choose to buy it, certain coverages (Liability, UM, MedPay) become mandatory.

What are the minimum limits if I buy insurance?

The “25/50/25” rule: $25k per person injury, $50k per accident injury, and $25k for property damage.

Does New Hampshire allow stacking?

Yes, but insurers can include anti-stacking language. You should check your specific policy wording.

Will my rates go up for a UM claim?

Generally, no. Since UM claims are caused by an at-fault uninsured driver, New Hampshire insurers typically do not surcharge you for these “not-at-fault” incidents.

What is MedPay?

It is a small, mandatory medical coverage ($1,000 minimum) that pays for yours and your passengers’ injuries regardless of who caused the accident.

What happens if I can’t pay for an accident I caused?

The state can suspend your driving privileges until you provide proof of a settlement or a payment plan, and you will likely be required to carry an SR-22 for several years.
