Summary

This study, conducted for the National Highway Traffic Safety Administration (NHTSA), aimed to quantify the current level of misuse of child restraint systems (CRSs) among the general public, specifically focusing on errors that increase injury risk. The research was motivated by prior studies indicating alarmingly high rates of CRS misuse and premature graduation to adult safety belts, which are associated with severe head, facial, abdominal, and spinal injuries. The project sought to provide NHTSA with updated data to inform enforcement and education strategies amidst evolving CRS technology and vehicle safety systems. Data collection occurred in the fall of 2002 across six states: Arizona, Florida, Mississippi, Missouri, Pennsylvania, and Washington. Researchers observed 5,527 children weighing less than 80 pounds in 4,126 vehicles. The methodology involved a workshop with medical and bioengineering experts to define "critical" misuse measures linked to injury severity. Field observers, required to be AAA-certified child passenger safety technicians, conducted observations at various community sites, including shopping centers and restaurants. The study recorded CRS type, installation status, harness tightness, and driver behavior. The results revealed that 62.3% of children were restrained in a CRS, 25.9% used a safety belt, and 11.8% were unrestrained. CRS usage declined significantly with age and weight, dropping from 97.1% for children under 20 pounds to 10.9% for those weighing 60–79 pounds. Critically, 72.6% of all observed CRSs exhibited at least one critical misuse. The most prevalent errors were loose harness straps securing the child and loose vehicle safety belts securing the CRS to the vehicle. Misuse rates varied by seat type, with infant seats showing the highest rate (83.9%) and belt-positioning boosters the lowest (39.5%). The study also found a strong correlation between driver and child restraint use: 91.7% of children transported by belted drivers were restrained, compared to only 62.3% of those transported by unbelted drivers. Additionally, improper use of LATCH systems and placement of rear-facing seats in front of active airbags were noted. The authors conclude that periodic monitoring of CRS misuse is essential due to continuous changes in vehicle safety technology and the constant influx of new parents. They recommend sustained enforcement of child passenger safety laws, particularly targeting booster seat violations, and enhanced education programs. These programs should emphasize correct CRS installation, the importance of keeping children in appropriate restraints for as long as possible, and proper use of LATCH systems. The findings underscore the widespread nature of critical misuse errors that compromise child safety, highlighting the need for targeted interventions to reduce injury risks.

Key finding

72.6 percent of child restraint systems observed contained critical misuse errors, primarily loose harness straps and loose vehicle safety belt attachments.
