Detailed Answer

Overview of Negligence in New Hampshire
In New Hampshire, to succeed in a negligence claim you must prove: duty of care, breach of that duty, causation and damages. In a collision at a traffic signal or highway exit, the key is showing the other driver violated a traffic law or standard of care and that this breach caused the crash.

1. Establish the Duty and Breach

All motorists owe a duty of care to others on the road under RSA 265:14 and RSA 266:1. For example:

2. Causation and Damages

You must show the breach directly caused your injuries or property damage. Documented medical records, repair estimates and expert opinions (e.g., accident reconstruction) help link the driver’s action to your losses.

Key Evidence to Gather

  • Police Crash Report: Contains officer findings, diagram, witness statements and any traffic citations.
  • Photographs and Video: Images of vehicle damage, skid marks, traffic signal status and road conditions. Dashboard cameras or nearby surveillance add detail.
  • Witness Statements: Contact information and written or recorded accounts from bystanders or passengers.
  • Accident Reconstruction: Expert analysis on vehicle speeds, impact angles and traffic signal timing.
  • Traffic Signal Logs: Many municipalities retain signal phase data confirming whether the light was red, yellow or green.
  • Vehicle Data: Electronic Event Data Recorder (“black box”) can record speed, braking or steering inputs seconds before the crash.
  • Medical Records and Repair Bills: Proof of your injuries and property damage, which establish damages.
