The correct answer is: 3

Measuring debris fields in a traffic crash from three points is a standard practice in accident reconstruction and investigation. By collecting measurements from three distinct locations, investigators can create a comprehensive understanding of the crash dynamics and the trajectory involved. This triangulation method helps to form a clear picture of how the vehicles interacted and the aftermath of the collision, allowing for more precise conclusions about the event. Using three points is particularly effective because it reduces the potential for error and provides a reliable framework for evaluating the physical evidence left at the scene. It creates a more robust data set that can assist in reconstructing the event, determining the positions of the vehicles after the crash, and supporting various analyses related to speed, direction, and impact forces. In contrast, measuring from fewer than three points may not capture the necessary detail and dimensional accuracy needed for thorough investigation and legal purposes, while measuring from more than three points may offer diminishing returns as it could complicate the reconstruction unnecessarily. Thus, the choice of measuring from three points strikes an appropriate balance between accuracy and practicality in the context of traffic crash investigations.
