Why is it important to conduct interviews during traffic crash investigations?

Conducting interviews during traffic crash investigations is crucial because they gather firsthand accounts that can clarify the circumstances surrounding the incident. Eyewitnesses, including the drivers, passengers, and pedestrians, can provide insights into how the crash occurred, the behaviors of those involved, and any contributing factors, such as road conditions or visibility. These details allow investigators to reconstruct the events with greater accuracy, leading to a more thorough understanding of the crash dynamics.

Furthermore, interviews help to fill in gaps that physical evidence alone may not reveal. For example, skid marks, vehicle damage, and debris can suggest certain actions, but the motives and decisions of the drivers involved can only be understood through personal accounts. This qualitative information is vital for determining liability and can influence legal proceedings and insurance claims.

While other options mention aspects that relate to traffic incidents, they do not directly address the primary investigative value of interviews in obtaining detailed and personal narratives that clarify what occurred during the crash.
