What is the role of a traffic investigator in a hit-and-run case?

In a hit-and-run case, the primary role of a traffic investigator is to gather evidence and identify the fleeing vehicle and driver. This involves meticulously examining the crash scene, collecting physical evidence, interviewing witnesses, and reviewing any available surveillance footage or photographs that could provide clues about the incident.

The investigator must document all relevant details related to the crash, such as the time, location, and any contributing factors like road conditions or vehicle speed. They will also look for distinctive characteristics of the fleeing vehicle, such as color, make, model, or license plate numbers, if identifiable. This crucial evidence helps to build a case, with the ultimate aim of locating the driver responsible for leaving the scene of the accident.

The other options provided serve different purposes. Imposing fines would be outside the scope of a traffic investigator's responsibilities, as law enforcement officers typically handle enforcement actions. Mediation between involved parties usually falls under the purview of insurance adjusters or legal representatives, not investigators focused on collecting evidence. Collecting insurance information from victims is also not aligned with the investigative role, which is centered on clarifying the circumstances of the crash and identifying violations of law.
