The mechanisms and severity of nonfatal injuries to children in crash and noncrash situations were compared: 82 children (15%) were involved in noncrash events and 466 (85%) were involved in crash events. Younger children (0 to 4 years of age) were more likely to be injured in a noncrash incident. The mechanism of injury was significantly different; 45% of the children injured in a noncrash event were ejected in contrast to 5% of the children injured in a crash event. Although more severe injuries were sustained in crashes, most of the children who were ejected in a noncrash event sustained at least moderate injuries. Use of restraint systems, door lock mechanisms, and appropriate passenger seating locations in the motor vehicle are three simple measures that could attenuate or eliminate noncrash injury.
