Traffic collision reconstruction

Reconstruction applies physics, vehicle dynamics, and scene evidence to explain how a crash likely occurred — speed ranges, impact angles, visibility, timing, and consistency with damage and rest positions.

Questions reconstruction can help answer

  • Impact sequence and approximate speeds or delta‑V ranges
  • Lane use, turning paths, and line‑of‑sight constraints
  • Braking, steering, and avoidance timing relative to hazards
  • Whether reported movements match tire marks, gouges, and debris patterns
  • Lighting, weather, and road‑surface effects on perception and control

Common applications

  • Intersection and left‑turn conflicts
  • Rear‑end and lane‑change impacts
  • Pedestrian and bicycle collisions
  • Run‑off‑road and roadside interactions
  • Commercial vehicle and multi‑vehicle chains

Typical materials reviewed

  • Police reports, photos, and scene diagrams
  • Dashcam, surveillance, or discovery video
  • ECM / EDR downloads and infotainment data when available
  • Vehicle inspections and repair estimates
  • Medical summaries and witness statements

Scope and opinions depend on the quality and completeness of case materials. Early preservation of scene documentation and vehicle evidence often makes the strongest foundation for analysis.
