What type of evidence should be collected to establish vehicle collision dynamics?

Collecting physical markings on the road is crucial for establishing vehicle collision dynamics because these markings provide tangible, objective evidence of how vehicles interacted during the incident. Factors such as skid marks, gouge marks, and points of impact can offer insights into the speed of the vehicles, the direction they were traveling, and the forces involved in the collision.

For instance, the length and location of skid marks can help accident reconstructionists determine whether a vehicle was attempting to brake before the impact, while gouge marks can indicate how deep a vehicle struck the road surface. All of this information is vital for reconstructing the sequence of events leading to the collision.

Other types of evidence, such as witness statements, vehicle speedometer readings, and driver’s statements, can provide additional context, but they are often subjective or reliant on individual recollections that may not be as reliable as the physical evidence found at the scene. Therefore, physical markings on the road serve as a foundational component in understanding the dynamics of a vehicle collision.
