 NTSB Opens Docket for Fatal 2015 Tennessee Work Zone Crash Investigation

​WASHINGTON — The National Transportation Safety Board opened the docket Monday for its ongoing investigation of a fatal 2015, Tennessee highway work zone crash, involving a semitractor-trailer and eight passengers vehicles.

The public docket contains only factual information collected by NTSB investigators, and does not provide analysis, findings, recommendations or probable cause determinations. No conclusions about how or why an accident occurred should be drawn from the docket. The docket opening marks a transition in the investigative process where the majority of facts needed for the investigation have been gathered and the NTSB can move ahead with analysis of those facts. Opening the docket affords those with a need and desire for its contents the opportunity review what factual information has been gathered about the accident. Any analysis, findings, recommendations, or probable cause determinations related to the accident will be issued by the Board at a later date.

The docket for this crash investigation contains interview summaries, investigative group factual reports, relevant photos, maintenance records, and a video study from a surveillance camera that captured traffic flow and the final accident sequence. Six people died in the crash. The NTSB also released the preliminary report for this accident on July 31, 2015.
