Dr. Robertson1 notes that the information on child seating position was obtained from the driver, raising a concern about the potential for information bias. As we2 reported in the manuscript, we have been able to compare these driver-reported data with evidence from on-site crash investigations for a subset of the sample, and we find excellent agreement. Our results are also consistent with recently-reported data on seating position of children obtained by direct observation.3 We therefore feel that bias in the reporting of seating position of children is minimal and not likely to affect the results of this study.
We concur with Dr. Robertson’s point that education coupled with legislation will change behavior more effectively than education alone. We noted in the paper that legislation (particularly through provisions in Graduated Driver Licensing laws to require rear seating of child occupants) would address one of the risk factors for front row seating. However, we also stated that educational efforts without supporting legislation can also change behavior. The results of our study, as well as others,4 demonstrate the effectiveness of public education efforts directed at reducing front row seating of children in vehicles equipped with passenger airbags.
