Ejections of Young Children in Motor Vehicle Crashes
Bibliographic record
Abstract
PURPOSE: The purpose of this study was to report the incidence of ejection from the vehicle among children involved in motor vehicle crashes, and to describe a novel mode of ejection from child safety seats. METHODS: The U.S. National Automotive Sampling System General Estimates System and the Fatality Analysis Reporting System databases from 1995 through 1999 were analyzed. A prospective two-center study of children involved in severe car crashes in Canada was performed. RESULTS: Only 0.2% of 5.5 million children involved in crashes experienced ejection, but 1924 (29%) of 6570 child fatalities involved ejections. Only 2.2% of children experienced rollover crashes, but these contributed 1832 (28%) of 6570 child passenger fatalities. Among 56 crashes, 5 restrained young children were ejected, 4 in rollover crashes. Ejection of a toddler through the shoulder straps of a forward-facing child safety seat was the mechanism of ejection in three of the five cases. CONCLUSION: Ejection from the vehicle is common (29%) among fatally injured children. Shoulder straps alone (as found in T-shield or overhead shield child seats) may not prevent the ejection of toddlers from child safety seats during rollovers.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
