Detailed Answer

Under New Jersey law, every driver must obey traffic-control signals and yield the right-of-way. Key statutes include N.J.S.A. 39:4-96 (traffic-control signal compliance) and N.J.S.A. 39:4-81 (right-of-way at intersections). To prove negligence in a crash at a traffic signal or exit, you must establish:

  1. Duty: The other motorist had a legal obligation to follow traffic signals and yield rules.
  2. Breach: The motorist violated a statute or failed to act as a reasonably careful driver.
  3. Causation: Their breach directly caused the collision.
  4. Damages: You suffered measurable losses (medical bills, repairs).

Gathering the right evidence is crucial. Below are common proof sources:

  • Accident scene documentation: Take photographs of vehicle positions, skid marks, traffic lights, road signs and road surface conditions immediately after the crash.
  • Traffic signal timing and maintenance records: Request logs from the municipality under OPRA to confirm signal phases or malfunctions.
  • Police crash report: Obtain a certified copy. It often includes diagrams, witness statements, officer findings and any citations (e.g., red-light violation).
  • Witness statements: Collect full names, contact details and written or recorded accounts describing what each person saw.
  • Video and camera footage: Retrieve dashcam, intersection camera or nearby business surveillance videos showing the sequence of events.
  • Accident reconstruction analysis: Hire a reconstruction expert to examine physical evidence, measure skid marks, analyze vehicle crush and calculate impact speeds.
  • Electronic data recorder (EDR) information: Many vehicles record pre-crash speed and brake use. Secure a download of that data.
  • Cell phone and distraction evidence: Subpoena phone records to show texting or calls at the time of the collision.
  • Vehicle damage assessments: Use repair shop estimates and photographs to demonstrate the collision’s force and point of impact.

Helpful Hints

  • Photograph and video the scene before vehicles are moved.
  • Get a copy of the full police report promptly.
  • Note down all witness names and contact info at the scene.
  • Preserve any available camera footage quickly—some sources overwrite after days.
  • Submit an OPRA request for signal timing and maintenance logs early.
  • Consult an accident reconstructionist to strengthen causation proof.
  • Keep all medical and repair bills organized to document damages.
