Summary
This research note by the National Highway Traffic Safety Administration (NHTSA) addresses the estimation of nonoccupant fatalities resulting from backing crashes, with a specific focus on children aged 1–4. The study was motivated by the significant risk these young children face due to their physical stature and limited comprehension levels, which make them particularly vulnerable in situations involving backing motor vehicles. A critical gap in existing data collection necessitated this analysis: the Fatal Accident Reporting System (FARS) only records fatal crashes occurring on public roads. Consequently, fatal backing crashes occurring on private property, such as residential driveways and private parking lots, are not captured in FARS because police accident reports are often not filed for incidents on private land. To address this blind spot, NHTSA’s National Center for Statistics and Analysis utilized data from the National Center for Health Statistics (NCHS), which derives cause-of-death information from death certificates across all 50 states, the District of Columbia, and New York City. The methodology involved contrasting NCHS data with FARS data for the calendar years 1992 and 1993, the most recent years available from NCHS at the time of publication. The study aimed to obtain average annual estimates of nonoccupant fatalities for both off-road and on-road backing crashes, disaggregated by age groups (children aged 1–4 versus all other ages). The authors note that due to the lack of detailed information on death certificates, the NCHS data provide an estimate of the maximum number of fatalities rather than an exact count. The findings reveal a stark disparity in risk between age groups and crash locations. Children aged 1–4, who constitute only 6% of the total U.S. population, accounted for 30% of all nonoccupant fatalities in off-road backing crashes. On average, 116 children in this age group were fatally injured in off-road backing crashes annually, contributing to a total of 390 fatalities of all ages in such incidents. In contrast, on-road backing crashes recorded in FARS resulted in an average of 85 total fatalities annually, with 14 (16%) being children aged 1–4. The data indicate that children aged 1–4 are significantly overrepresented in off-road backing crash fatalities relative to their population size. The significance of this study lies in its identification of children aged 1–4 as a particularly high-risk demographic in backing crash scenarios, especially in off-road environments where standard traffic safety data collection fails to capture the full scope of fatalities. While the absolute number of fatalities in backing crashes is small relative to total traffic fatalities, the disproportionate impact on young children highlights a critical area for safety intervention and data improvement. The study underscores the limitations of relying solely on police-reported data for comprehensive traffic safety analysis and demonstrates the utility of health statistics in identifying hidden safety risks.
Key finding
Children aged 1-4 made up about 6% of the population but 30% of off-road backing-crash nonoccupant fatalities, averaging 116 child deaths per year out of roughly 390 total.
