Mastering Forensic Crash Investigation: The IBF Protocol

Practice close, wide-angle photography at a standard focal length to preserve depth; avoid excessive zoom and portrait framing, and shoot in landscape format for evidence, while securing equipment with straps.

Identify volatile evidence at crash scenes first, including weather, final resting positions, bodily fluids and deposits inside vehicles, and extrication damage, since these elements can change with time.

Identify and document temporary evidence at crash scenes, such as tire marks, license plates, license discs, driving licenses, and lighting conditions, while noting their volatility and tampering risks.

Identify long term evidence in crash scenes, such as road design and markings, damage to bridges, wheel marks, and tree contact, while distinguishing from volatile evidence to collect promptly.

Learn how to interview subjects at crash scenes, including drivers, witnesses, independent witnesses, and victims, and how to minimize bias using narrative versus deposition style interviews and targeted questions.

the ibf protocol divides the scene investigation into four focus areas, prioritizing volatile evidence first and balancing short-term versus long-term evidence while using color-coded tasks for primary and secondary investigators.

Capture the first arrival image by photographing what you saw when you arrived, where you stopped, and the direction of the crash scene to provide a reliable, court-ready record.
