When might eyewitness accounts be particularly useful?

Eyewitness accounts can be particularly valuable in traffic crash investigations when it comes to estimating speeds and describing maneuvers during the incident. Eyewitnesses may provide first-hand perspectives on how fast vehicles were traveling, the actions of the drivers leading up to the crash, and the overall dynamics of the situation. This information can be crucial for reconstructing the event and understanding the contributing factors to the crash.

While other evidence like physical damage, skid marks, and such can help establish facts, eyewitness descriptions can complement this data by providing insights into the sequence of events that may not be captured by physical evidence alone. They might report on the behavior of drivers or how the vehicles interacted just before and during the collision, which can lead to a more comprehensive understanding of the circumstances surrounding the crash.

In contrast, other options might imply situations where eyewitness accounts could be considered less useful. For example, relying solely on them or deeming them rarely useful ignores their potential impact in situations where they fill in gaps that physical evidence may not fully explain.
