Special Crash Investigations, On-Site Small Overlap/Oblique Impact Investigation, Vehicle: 2014 GMC Acadia, Location: Missouri, Crash Date: June 2016

This report documents the on-site investigation of a small overlap/oblique impact to a 2014 GMC Acadia. This crash occurred on a narrow, two-lane, rural roadway with no pavement markings. The GMC was a 4-door sport utility vehicle (SUV) equipped with multi-stage frontal air bags, front-center air bag,front seat-mounted side impact air bags, and rollover/side impact inflatable curtain (IC) air bags that were not compliant to Federal Motor Vehicle Safety Standard (FMVSS) No. 226, “Ejection Mitigation.” An unbelted 41-year-old female drove the vehicle. The GMC was traveling east in the eastbound lane approaching a hill crest. A 2011 Chevrolet Cruze was traveling west and was partially in the eastbound lane. The GMC crested the hill as the Chevrolet was approaching the hill crest. The front left corner of the Chevrolet struck the front left corner of the GMC (Event 1). The impact resulted in a stage 1 and 2 deployment of the GMC’s driver’s frontal air bag and deployment of the both IC air bags. The GMC’s Event Data Recorder (EDR) reported the maximum longitudinal and lateral velocity changes as -42 km/h (-26 mph) and 3 km/h (2 mph), respectively. The impact caused both vehicles to rotate counterclockwise (CCW). The rear portions of the GMC and Chevrolet then departed the south and north sides of the road, respectively, and the right quarter panel of each vehicle struck a woven wire fence (Events 2 and 3) as both vehicles came to final rest. The driver of the GMC sustained police-reported “B” (non-incapacitating) injuries and was transported by ambulance to a trauma center where she was treated in the emergency room for moderate severity injuries and released. A belted 21-year-old female driver occupied the Chevrolet. She sustained police-reported “B” (non-incapacitating) injuries and was transported by ambulance to a trauma center. The driver’s injuries and level of treatment are not known. Both vehicles were towed from the crash scene due to damage.
