University of Utah researchers found that backing up in the driveway is not a well  recognized and often very serious type of mishap for small children. They analyzed data on 495 children treated for injuries sustained in auto-pedestrian accidents over an eight year period, of which 128 occurred in the driveway. Six percent of the children died. Cars, trucks, and sports utility vehicles were involved in 55 percent, 25 percent, and 12 percent of the incidents, respectively. The number of cases increased over the last four years of the study.
