Special Crash Investigations On-Site Guardrail End Treatment Impact Investigation; Vehicle: 2008 Mercury Mariner Location: Pennsylvania Crash Date: November 2016

The interest in this on-site investigation was the impact to an ET-Plus guardrail end treatment by a 2008 Mercury Mariner. The crash occurred when the eastbound Mercury traveling the limited-access interstate highway departed the right side of the road and struck the guardrail end treatment during early morning hours. The Mercury was occupied by a 19-year-old female driver and a 20-year-old female in the front row right occupant terminal was displaced along a portion of the guardrail and deformed the W-beam. A section of the W-beam guardrail penetrated the left toe pan of the vehicle and breached the occupant compartment to the rear seats. The two occupants in the vehicle were transported by ambulance from the scene with police-reported C-level “possible” injuries. The crash was identified by the Pennsylvania Turnpike Commission (PTC), which in turn submitted notification to the Federal Highway Administration (FHWA). The FHWA determined that the crash type and guardrail end treatment met the criteria for further research and subsequently forwarded the notification to the Crash Investigation Division (CID) of the National Highway Traffic Safety Administration in November 2016. The CID assigned an on-site investigation of the crash to the Special Crash Investigations (SCI) team at Crash Research & Analysis, Inc., the same day. In turn the SCI team initiated contact with the PTC for the on-site investigation.
