Special Crash Investigations: On-Site Guardrail End Terminal Crash Investigation; Vehicle: 2004 Jeep Grand Cherokee; Location: Missouri; Crash Date: November 2017

This report documents the on-site investigation of an SUV impact to an ET-Plus 10 cm (4 in.) model guardrail end terminal that is of interest to the Federal Highway Administration. This crash occurred in the median on the north side of the eastbound lanes of a five-lane, divided interstate highway. The Jeep was a 4-door SUV equipped with dual-stage frontal air bags. The vehicle was not equipped with an event data recorder (EDR) supported by the Bosch Crash Data Retrieval tool. An unbelted 23-year-old male drove the vehicle. The Jeep was traveling in a right curve in an undetermined eastbound lane. Witnesses reported to police that the vehicle passed them at a high rate of speed several miles prior to the crash site and the vehicle was “swerving all over the road.” The Jeep departed the left side of the roadway into the median and the front plane struck the end terminal. The impact displaced the guardrail system and the Jeep rolled over, right-side-leading. The unbelted driver was ejected during the rollover and came to rest on the westbound roadway and was subsequently run over and possibly dragged by another vehicle. The Jeep came to final rest on its wheels in the median facing north. The driver sustained fatal injuries and was pronounced deceased at the crash scene. The Jeep was towed from the crash scene due to damage.
