How should a sketch be done in a traffic crash incident?

In a traffic crash incident, a sketch is essential for documenting the scene accurately, and the triangulation method is a highly effective approach for achieving this. By measuring from specific points at the area of impact using the triangulation method, investigators can create a precise representation of the scene. This technique involves measuring the distance from two or more fixed points to the locations of vehicles, debris, and other relevant features, allowing for accurate positioning on the sketch. This method increases the reliability of the sketch, as it provides a scale and orientation that can be referenced later in investigations.

Other methods like estimating distances can lead to inaccuracies and potentially jeopardize the integrity of the investigation. Relying solely on photographs may not capture the same spatial relationships needed for a thorough understanding of the incident layout. While computer software can help in creating diagrams or analyzing data, it is important to have accurate measurements to input into these systems for them to be effective. Therefore, the triangulation method stands out as the most reliable way to document a crash scene sketch correctly.
