Summary

This document, published by the National Highway Traffic Safety Administration (NHTSA) in 2021, serves as a technical summary of effective countermeasures for child passenger safety (CPS). It addresses the persistent problem of motor vehicle traffic crashes, which remain a leading cause of death for children aged 14 and younger. In 2018, 1,038 children died in traffic crashes, with 77% of fatalities occurring among vehicle occupants. Despite the proven efficacy of child restraint systems (CRSs)—which reduce fatalities by 71% for infants and 54–59% for toddlers—misuse rates are estimated at least 46%, and restraint usage declines with age, dropping to 86.5% for children aged 8 to 12. The paper aims to guide State Highway Safety Offices in selecting evidence-based interventions to improve compliance and reduce injuries. The text evaluates six behavioral countermeasures, categorizing them by effectiveness levels ranging from "consistently effective" to "promising." The analysis draws on data from sources such as the National Survey of the Use of Booster Seats and the National Child Restraint Use Special Study. The two most effective countermeasures, rated with five stars, are strengthening child/youth occupant restraint laws and short-term high-visibility law enforcement. Laws requiring booster seats improve safety outcomes, though driver restraint status is the strongest predictor of child restraint use. High-visibility enforcement campaigns are most effective when coupled with media announcements and concurrent child restraint inspection stations. Three additional countermeasures are rated as promising or likely effective (three stars): strategies for older children, strategies for CRS and booster seat use, school-based programs, and inspection stations. Communication and outreach programs targeting both parents and children are more effective than those focusing on only one group. Inspection stations, particularly those staffed by certified technicians, significantly improve CRS installation accuracy and appropriate restraint selection. School-based programs have demonstrated lasting effects on seat belt and CRS use, though their widespread adoption remains unclear. The document notes that costs vary significantly; while enforcement campaigns can be expensive, low-resource settings can leverage community events and existing infrastructure like schools and fire departments to implement outreach effectively. The significance of these findings lies in the identification of a comprehensive strategy for reducing child traffic fatalities. The paper concludes that the most impactful approach combines strong legislative frameworks with rigorous enforcement. Furthermore, it emphasizes the importance of tailoring interventions to specific community needs and leveraging existing resources to maximize reach and minimize cost. A critical insight is the linkage between adult and child safety; pairing CPS countermeasures with adult seat belt efforts enhances overall efficacy. By providing a clear hierarchy of intervention effectiveness, the report enables safety professionals to prioritize resources toward strategies that demonstrably reduce misuse and increase proper restraint usage.

Key finding

Strong child occupant restraint laws and short-term high-visibility law enforcement campaigns are identified as the most effective countermeasures for improving child passenger safety.
