Why are timelines utilized in traffic crash investigations?

Timelines are an essential tool in traffic crash investigations because they establish a clear sequence of events leading up to the crash. By organizing events chronologically, investigators can better understand how various factors contributed to the incident. This includes actions taken by the drivers, changes in speed, road conditions, and any other relevant occurrences that preceded the collision. A well-constructed timeline helps paint a comprehensive picture of the crash dynamics, assisting in determining fault, understanding causation, and identifying any potential safety issues that may need to be addressed.

While timelines have relevance for legal documentation and may indirectly affect the interests of insurance companies, their primary function in an investigation is to clarify the order of events rather than serve purely administrative purposes.
