A bicycle visibility question can involve several different subjects: what lighting the law required, which equipment was present, whether it was operating, what the surrounding light and weather were, where each road user was positioned, and what an image or witness actually records. A useful evidence inventory keeps those subjects separate and preserves the source for every observation.

Legal lighting requirements, the physical condition of equipment, and what a particular road user could perceive from a particular position are separate questions that should not be collapsed into one visibility conclusion.

Record the legal time and location context

North Carolina General Statute 20-129 addresses when vehicle lighting is required and, in subsection (e), specifies bicycle equipment for nighttime operation on a public street, public vehicular area, or public greenway. Record the crash time, time source, sunset or lighting context, roadway classification, and exact location before applying the current statutory text.

  • Front lamp, rear lamp, rear reflex mirror, and bright clothing or vest identified separately
  • Make, model, serial number, mount location, orientation, lens or reflector condition, operating mode, charge or battery state, and post-crash damage
  • Photograph or video of the item in place before removal when safely available, followed by packaging and storage details
  • Purchase, manual, specification, charging, maintenance, replacement, application, or device record linked without assuming it proves operation at the crash time

Separate equipment condition from operating status

A lamp may be physically present but switched off, discharged, damaged during the collision, obscured, pointed away from traffic, or operating in a mode not visible in every image frame. Conversely, post-crash damage does not by itself establish the pre-crash condition. Record each observation, test, time, person, method, and limitation. Avoid destructive testing or alteration when the original condition may matter.

Build an environmental visibility record

  • Natural light, street lighting, storefront or vehicle lighting, weather, precipitation, glare, shadow, and contrast
  • Road geometry, grade, curve, lane, bicycle facility, intersection controls, vegetation, work-zone material, parked vehicle, sign, or other obstruction
  • Cyclist path, motor-vehicle path, direction, estimated position, and the source supporting each position
  • Witness location, height, direction of view, movement, obstruction, duration, and lighting at the time of the observation

Keep report fields and source observations distinct

The current NCDMV DMV-349 Instructional Manual defines fields used for lighting, weather, road condition, traffic control, vehicle factors, non-motorist action, and the crash narrative and diagram. A report entry identifies what was recorded in that report. Compare it with the underlying source and do not treat a code as a reconstruction of what every person could see.

Preserve photograph and video provenance

  • Original file, device or system, owner, capture time, timezone, filename, metadata, export method, and full clip or sequence
  • Camera position, direction, lens or zoom, exposure, automatic processing, compression, frame rate, and any missing interval
  • Working copy, crop, still frame, enhancement, annotation, and conversion saved separately from the original
  • Request, response, download, share link, retention notice, and chain of possession documented for third-party material

North Carolina Rule of Evidence 901 addresses authentication or identification as a condition of admissibility. Preserving source and process information does not guarantee admissibility, but it avoids losing basic facts about what a file or item is claimed to be.

Connect visibility to location evidence

The related guide to documenting a Charlotte bicycle-crash location before conditions change explains how to preserve lane layout, controls, surface conditions, sight lines, and temporary features. Use that location record to test viewpoints; do not replace it with a general statement that someone was or was not visible.
