Abstract 

A 49-year-old male pedestrian was fatally injured when an overloaded truck backed over him and two of the truck's rear wheels rolled over his chest. An analysis is presented to estimate whether or not the subject would have been severely injured if the truck had been loaded to the maximum-permitted weight. The magnitude of compression of the subject's chest is predicted both for the case weight and the maximum-permitted weight of the vehicle. These predicted magnitudes of chest compression are then used to predict the probability of thoracic injury in both cases. The analysis suggests that loading by either the case weight or the maximum-permitted weight of the vehicle would have caused very severe compressions of the chest, likely resulting in multiple rib fractures, collapse of the ribcage and injury to the thoracic organs. Thus, this analysis suggests that severe, possibly life-threatening, thoracic injury would have occurred if the vehicle was loaded to its maximum-permitted weight.
