The documentation and recording of evidence at a collision scene primarily assist in determining the cause of the collision. This process involves gathering detailed information about the circumstances surrounding the incident, including the positions of vehicles, road conditions, weather, and any contributing factors such as traffic signals or sign visibility.

By meticulously documenting these elements, investigators can analyze how the collision occurred and which factors led to it. This can involve physical evidence such as skid marks, debris patterns, or vehicle damage patterns, which all provide insights into the dynamics of the collision. Establishing the cause is crucial for understanding liability, improving road safety, and preventing future accidents.

While information about the number of vehicles involved, damage costs, and the location of the incident may also be documented during this process, they do not directly contribute to understanding why the collision happened as comprehensively as the evidence surrounding the cause does.
