Who is considered the most important person on the scene of a collision?

The at-scene investigator is considered the most important person on the scene of a collision because their primary responsibility is to gather and analyze evidence related to the incident. This role is crucial for establishing the facts surrounding the collision, including identifying the causes, collecting witness statements, and documenting the scene through photographs and diagrams. The investigator's findings are essential for accurate reporting, which can influence insurance claims, legal proceedings, and traffic safety measures. Their expertise helps ensure that the investigation is thorough and that all relevant factors are considered, ultimately aiding in understanding how the collision occurred and preventing future incidents.
