What is the primary goal of an investigator at a collision scene?

The primary goal of an investigator at a collision scene is to ensure that the scene remains safe and to prevent any further damage or injury. This involves taking immediate actions like securing the area, directing traffic, and ensuring that any hazards are mitigated. By keeping the scene from getting worse, the investigator can preserve vital evidence and ensure the safety of everyone involved, including other drivers, pedestrians, and emergency responders.

The other roles such as gathering witness testimonies, enforcing traffic laws, and documenting vehicle damages are indeed important, but they come after the initial concern of scene safety. Once the investigator has secured the area and ensured it is safe, they can then focus on these other activities to gather information and assess the incident thoroughly.
