A yellow-light intersection crash may involve signal phase, distance, speed, turning movement, lane position, visibility, traffic queues, and the timing of more than one road user. The color observed by one person is important, but it does not by itself reconstruct the event.

The evidence file should connect each vehicle’s movement to a time source, viewpoint, signal phase, roadway feature, and physical record while preserving uncertainty.

Map movements and time sources

  • Intersection, approach, lane, direction, intended movement, stop line, crosswalk, signal heads, signs, and sight obstructions
  • First observation of each vehicle or road user and the signal indication from that viewpoint
  • Photograph or video timestamp, device clock accuracy, frame sequence, witness location, and traffic-controller record if available
  • Vehicle damage, debris, tire marks, rest positions, report narrative, and later citation disposition

Request changing evidence promptly

Identify whether video may be held by the city, state, transit agency, business, residence, or private vehicle. Record the owner, exact camera, requested time window, request date, preservation language, and response. Do not assume that a traffic-management camera records or retains video.

Separate seeing yellow from the vehicle’s position

A witness might see yellow at impact without seeing the signal when a vehicle entered the intersection. Preserve those as separate observations. Identify the signal head facing each lane, whether the movement was straight or turning, and which part of the sequence a witness or recording actually captures.

For example, a recording that shows the collision but leaves the signal outside the frame may help establish vehicle movement while leaving the controlling indication unresolved. A timing plan can describe programmed operation; whether it establishes the phase during this particular event depends on the record, system, and conditions. Do not treat either source as proof of an unseen signal without a supported connection.

Gather existing records from a safe location. Do not stand in traffic, recreate the approach, or handle signal equipment to test an account. Keep the original video and any missing intervals or clock differences noted for review.

Use official records for the questions they can answer

Under G.S. 20-158, a steady yellow circular signal or steady yellow arrow at an intersection warns that the corresponding green phase is ending or red is about to follow. A flashing yellow signal has a different rule: proceed cautiously while yielding to traffic in or approaching the intersection. Record which indication was present rather than writing only “yellow.” See North Carolina General Statute 20-158.

The Department of Insurance checklist identifies basic driver, vehicle, insurer, policy, witness, and scene information. See North Carolina Department of Insurance: After an Accident.

Connect the file to the next decision

Build competing timelines when the evidence supports more than one sequence, then identify the single record most likely to resolve the difference. The traffic-camera preservation guide explains how to identify a recording’s custodian and distinguish a preservation request from obtaining a copy.

When the signal sequence remains disputed, our car accident team can review the available accounts and records with you. A signal-color label alone does not establish responsibility for the crash.
