During a traffic crash investigation, what is the recommended action regarding witnesses?

The recommended action during a traffic crash investigation regarding witnesses is to keep them separate. This approach helps to ensure that each witness provides their independent account of the events without being influenced or swayed by the statements of others. When witnesses are allowed to discuss the incident with each other, there is a risk that their memories may become intertwined or altered, which can compromise the integrity of the individual testimonies.

By keeping witnesses separate, investigators can obtain more reliable and accurate information about the crash, allowing for a clearer understanding of what occurred. This method aids in building a comprehensive and factual narrative of the event, which is crucial for determining liability, understanding the circumstances of the crash, and supporting any legal proceedings that may follow.
