What is a crash investigation site?

Crash investigation sites are locations where trained investigators examine the circumstances surrounding a vehicular collision. These sites are often the location of serious or fatal accidents and are staffed by a team of experts who are trained in accident investigation. The purpose of these investigations is to determine the cause of the accident, identify contributing factors, and recommend ways to prevent similar accidents in the future. The site may be closed to the public during the investigation, and motorists may be asked to avoid the area. The team will typically document the scene through photographs and diagrams, collect physical evidence, and conduct interviews with witnesses and those involved in the accident. The investigation may take several hours or days, depending on the complexity of the case. After the investigation is complete, a report will be written detailing the findings and recommendations for improvement, if applicable.
