This report documents the investigation of an alleged rollover crash involving a 2016 Chevrolet Equinox and a 1994 Mack CH600 dump truck and the fatal injuries sustained by all three occupants of both vehicles. The crash occurred in a four-leg intersection controlled by stop signs for eastbound and westbound traffic in a rural area of South Dakota in June 2018. The Chevrolet was being driven northbound by a belted 79-year-old male and was pulling a two-wheel utility trailer. A belted 71-year-old female occupied the front row right seat position. The Mack was being driven westbound by a belted 82-year-old male who entered the intersection without stopping. The front plane of the Chevrolet struck the left plane of the Mack. The Chevrolet was displaced to the left and departed the roadway on the left edge, and the trailer separated and departed the roadway on the right edge. The Mack departed the roadway on the right edge where it overturned onto its left plane. The investigation concluded no rollover event involving the Chevrolet occurred in this crash. Following the crash, all occupants from both vehicles were transported by ambulances to an area hospital. Both occupants of the Chevrolet were pronounced deceased soon after the crash and the driver of the Mack died as a result of his injuries 15 days after the crash. Both vehicles were towed from the scene due to damage.
