What is recommended to photograph before any marks are placed at the scene?

Photographing the overall area of the crash scene before any marks are placed is crucial for capturing the original conditions and layout of the scene. This allows investigators to maintain a complete and accurate record of where the vehicles were positioned, the context of the location, and any other relevant features that could affect the investigation. This initial documentation serves as a vital reference point for understanding the dynamics of the crash and for reconstructing events later on.

Having a clear visual representation of the scene before any alterations or markings are made ensures that all details, including skid marks, debris, and vehicle positions, can be assessed in their original state. This can provide significant insight into factors such as vehicle speed, direction of travel, and the impact points that would be essential for a thorough analysis of the incident. Therefore, capturing an unaltered view of the overall area is a critical step in the traffic crash investigation process.
