Motorcycle accidents in New Hampshire carry unique legal complexities that set them apart from other motor vehicle claims. NH is the only state without a mandatory adult helmet law, the state's modified comparative fault system under RSA 507:7-d creates additional hurdles for injured riders, and insurance gaps from NH's no-mandatory-insurance policy can leave riders exposed. If you've been injured in a motorcycle accident, understanding these legal issues is essential to protecting your claim. Apis Law provides experienced motorcycle accident representation throughout New Hampshire.
Motorcycle Accident Statistics and Risks in New Hampshire
Motorcycle fatalities in New Hampshire have been rising. According to the National Highway Traffic Safety Administration (NHTSA), motorcyclists are 29 times more likely to die per mile traveled than passenger car occupants.
In 2023, New Hampshire saw a significant increase in motorcycle fatalities, highlighting the ongoing danger riders face on NH roads. The combination of narrow rural highways, harsh weather transitions, and tourist traffic during motorcycle season creates a particularly hazardous environment for riders.

New Hampshire Motorcycle Laws That Affect Your Claim
Helmet Requirements Under RSA 265:144
New Hampshire is the only state in the nation that does not require adult motorcycle riders to wear a helmet. Under RSA 265:144, only riders under 18 are required to wear a helmet. However, not wearing a helmet does not bar a rider from recovering damages after an accident. Insurance companies frequently argue that a helmetless rider's injuries were worsened by the lack of a helmet, but this is a damages argument—it does not eliminate your right to compensation. An experienced attorney can counter this defense by demonstrating that the collision itself, not the absence of a helmet, caused the injuries.
Comparative Fault in Motorcycle Cases (RSA 507:7-d)
New Hampshire's modified comparative fault statute, RSA 507:7-d, allows an injured party to recover damages only if their fault does not exceed 50%. If you are found 51% or more at fault, you are completely barred from recovery. In motorcycle cases, insurers aggressively argue that the rider was at fault—whether for speeding, lane positioning, or failing to take evasive action.

Financial Responsibility and Insurance (RSA 264:1)
New Hampshire does not require motorcycle riders to carry liability insurance, but RSA 264:2 requires all motorists to demonstrate financial responsibility if involved in an accident. This means riders who cause accidents without insurance face personal liability for damages.
More critically for injured riders, RSA 264:15 requires riders to carry uninsured/underinsured motorist (UM/UIM) coverage, which is essential protection if struck by a driver who lacks adequate insurance. Given NH's no-mandatory-insurance environment, UM/UIM coverage is one of the most important protections a motorcyclist can carry.
Common Causes of Motorcycle Accidents in NH
The most common cause of motorcycle accidents is a left-turn collision, where a vehicle turns left in front of an oncoming motorcycle. Other frequent causes include rear-end collisions, unsafe lane changes, road hazards (potholes, debris, gravel), and hit-and-run accidents. In Vachon v. New England Towing, 148 N.H. 429 (2002), the NH Supreme Court addressed the duty of care owed by motor vehicle operators, holding that all drivers must exercise reasonable care to avoid foreseeable harm. Similarly, Bennett v. Lembo, 145 N.H. 276 (2000), reinforced that the standard of care requires drivers to be aware of vulnerable road users—including motorcyclists.

Damages Available in NH Motorcycle Accident Cases

Injured motorcyclists may recover both economic and non-economic damages. Economic damages include medical expenses (emergency care, surgery, rehabilitation, future treatment), lost wages, diminished earning capacity, and property damage. Non-economic damages compensate for pain and suffering, emotional distress, loss of enjoyment of life, and permanent disfigurement or disability. For a detailed explanation, see our guide on non-economic damages in NH personal injury cases.
The NH Supreme Court addressed damages valuation in Marcotte v. Timberlane/Hampstead Sch. Dist., 143 N.H. 331 (1999), establishing that damages must be supported by evidence of actual losses and reasonable future projections. Additionally, under RSA 524:1-b, injured parties are entitled to pre-judgment interest if the case proceeds to trial, creating a financial incentive for defendants to settle rather than litigate.
Steps to Protect Your Claim After a Motorcycle Accident
The actions you take immediately after a motorcycle accident can significantly impact your claim's outcome:
Call 911 and request police response. An official accident report is critical evidence. Learn more about accident reports in NH.
Seek immediate medical attention, even if injuries seem minor. Delayed symptoms are common with TBI and internal injuries. Medical records created on the day of the accident are powerful evidence.
Document the scene: photograph your motorcycle, the other vehicle(s), road conditions, your injuries, and your riding gear.
Preserve your helmet and gear. Damaged equipment is evidence of impact severity.
Do not give recorded statements to insurance companies without speaking to an attorney first. Insurers use these statements to minimize your claim.
Contact an attorney promptly. Under RSA 508:4, you have three years to file a personal injury lawsuit in New Hampshire, but evidence degrades over time.
Insurance Challenges in Motorcycle Claims
Motorcycle accident claims face unique insurance challenges. Health insurers frequently assert a lien on any settlement or verdict, seeking reimbursement for medical expenses they covered. This subrogation right can significantly reduce your net recovery if not properly negotiated. Additionally, because New Hampshire does not mandate auto insurance, many at-fault drivers carry minimal or no coverage. In these situations, your own UM/UIM coverage under RSA 264:15 becomes your primary source of compensation. Understanding your policy limits and coverage stacking options is critical before an accident occurs.

Frequently Asked Questions
Do I have to wear a helmet when riding a motorcycle in New Hampshire?
No. Under RSA 265:122, only riders under 18 are required to wear a helmet in New Hampshire. NH is the only state without a mandatory adult helmet law. However, not wearing a helmet does not bar you from recovering damages after an accident, although insurers may argue it contributed to the severity of the injury under comparative fault (RSA 507:7-d).
Can I recover damages if I was partially at fault for my motorcycle accident?
Yes, as long as your fault does not exceed 50%. Under RSA 507:7-d, New Hampshire's modified comparative fault statute, you are barred from recovery only if you are 51% or more at fault. The NH Supreme Court established the framework for these determinations in Bohan v. Ritzo, 141 N.H. 210 (1996).
What damages can I recover after a motorcycle accident in NH?
You may recover economic damages (medical expenses, lost wages, future care costs) and non-economic damages (pain and suffering, emotional distress, loss of enjoyment of life). The NH Supreme Court addressed damages valuation in Marcotte v. Timberlane/Hampstead Sch. Dist., 143 N.H. 331 (1999). Pre-judgment interest under RSA 524:1-b may also apply.
How long do I have to file a motorcycle accident claim in New Hampshire?
Under RSA 508:4, you have three years from the date of injury to file a personal injury lawsuit in New Hampshire. This is a hard deadline. If you miss it, your claim is permanently barred regardless of its merits.
What should I do immediately after a motorcycle accident?
Call 911, seek immediate medical attention, document the scene with photos, preserve your helmet and gear as evidence, do not give recorded statements to insurance companies, and contact an attorney. Evidence quality degrades over time, so acting quickly strengthens your claim.
