Comparative Negligence (51% Rule)

In New Hampshire, the victim in a car accident can sue the negligent driver for compensation. The victim’s liability in causing the accident, their comparative negligence, affects the amount of compensation the victim receives.

If the victim contributed less than 51% of the negligence that caused the accident, then their compensation is reduced by the amount they contributed to the accident. If the victim contributed 51% or more of the negligence that caused the accident, then the victim is barred from receiving any compensation.

NH Code § LII-507-7-d

Example of Comparative Negligence (51% Rule)

One morning, Jackson was driving north on his way to work. At an intersection, he pulled into the left turn lane. At the same time, Melanie approached the intersection from the opposite direction. Suddenly, Jackson turned left into Melanie’s lane and their cars collided.

Melanie sustained serious brain injuries and damage to her car, totalling in $100,000 dollars worth of damages.

After their investigation, the police determined that Jackson had failed to yield according to traffic laws. A pedestrian witness told police he saw Melanie texting at the time Jackson’s car crashed into Melanie’s. As a result, the police issued Melanie a citation for using a mobile device while driving.

Melanie sued Jackson for $100,000 and claimed he was 100% at fault for the accident because he did not yield to her right-of-way. At trial, the jury found Jackson liable for failing to yield the right-of-way. However, the jury also found Melissa liable for using a mobile device while driving and partially responsible for the accident.

The verdict stated Jackson’s negligence equaled 70% of the accident, and Melanie’s equaled 30%. The jury awarded Melanie only $70,000 dollars.

In the event the jury had found Jackson’s negligence equaled 49% of the accident, and Melanie’s equaled 51%, the jury would be barred by law from awarding Melanie any compensation for the damages.

New Hampshire’s Fault-based Car Insurance

In New Hampshire, the law does not require car owners to purchase auto insurance, but they must be able to demonstrate that they can provide sufficient funds to meet New Hampshire Motor Vehicle Financial Responsibility Requirements in the event of an at-fault accident.

If a driver is unable to meet these requirements, their driving privileges in New Hampshire may be suspended. Victims can file a claim with either their own insurance company or the insurance company of the at-fault driver.

Statute of Limitations

New Hampshire has a three (3) year statute of limitations for personal injury claims. If the victim fails to file their claim within the three (3) year period following an accident, then the victim is barred from pursuing the negligent driver in court.

NH Code § LII-508-4

New Hampshire Government Tort Claims – Sovereign Immunity

In New Hampshire, it is possible to submit a claim against a governmental agency or its employees for personal injury or property damage as a result of negligence on the part of the governmental agency or its employees.

The claim must refer to an lawful action on the part of the governmental agency or employee performed in the scope of their duties. If the injury or property damage occurred as a result of an unlawful action, then the claimant can sue only the person(s) who caused injury or property damage individually. The governmental agency would not be liable.

New Hampshire places caps of $475,000 per claimant and $3.75 million per incident as the maximum amount of damages that can be claimed against a government agency or its employees.

A government tort claim must be filed against the governmental agency responsible for the car accident within 180 days following the accident.

NH Code § LV-541-B-14

Example: Government Employee Causes Car Accident

If Melissa, an engineer with the Manchester Planning Department, ran a red light on her way to a worksite and caused an accident, then the City of Manchester would be liable for the property damage and personal injuries caused by her.

If Melissa stopped for a few drinks and became intoxicated before heading to a worksite and causing an accident, then the City of Manchester can claim sovereign immunity. Melissa performed an unlawful act and was not acting in the scope of her duties when she became intoxicated on her way to the worksite.

To seek compensation for damages, injured parties would have to sue Melissa personally. The determination of whether or not Melissa was acting within the scope of her duties would have to be decided during a trial.
