Courtroom Exhibits

A single photograph or digital video can be crucial in the identification of evidence and ultimate reconstruction of a collision by our experts. Likewise, a properly prepared 3D animation can be an influential factor in accurately relating a scientific opinion. Our reconstructionists take pride in their investigative efforts and expert exhibits they produce.

3D Illustrations

3D illustrations can be produced by our experts to exhibit the dynamic interaction between vehicles when they collided and moved off to final rest. 

Accident Scene Photographs

Accident scene photographs can serve as a basis for many expert opinions, including the positioning of vehicles on the roadway before a crash, or their orientation when they collided.

Computer Generated Diagram

Pictured above is a computer generated scale diagram set over an actual aerial photo. Effective visual aids are often crucial in explaining the actions of the vehicles prior-to, during, and immediately after an accident.

Diagrams can be provided in printed form or on CD, with or without an animated effect. Scale diagrams are offered as part of our accident reconstruction service.


Based on scientifically reliable methods, traffic crashes can be animated, placing a person in the position of a driver, witness, or other participant. When properly applied, an animated view is an impressive resource.  

In the above animation, the Semi-truck driver has crossed left of center and is on a collision course with the pickup truck ahead of him.  A witness approaches in the opposite direction. 


Our accident investigation and reconstruction services may include, but are not limited to, at-scene investigation, photography, scale diagramming, crash data retrieval, mathematical analysis, and preparation of court trial materials. Regardless of the case, our professional services are tailored to meet the needs of our clients.

Thousands of accidents occur throughout the United States every day. Effective accident reconstruction techniques help our experts determine if the actions of drivers, failures of equipment, or environmental factors played a role in a collision. Crash Data Services, LLC prides itself on developing informative conclusions based on scientifically validated methodologies.
