scope:

SUMMARY: This document denies a rulemaking petition submitted by Mr. James E. Hofferberth on April 1, 2013. His petition includes two requests: (1) To regulate the performance of supplementary automotive restraint systems that are marketed specifically for pregnant women; and (2) to require prominent warning labels in all vehicles with the intent of informing pregnant women that ''seat belts could injure or kill their unborn child,'' specifically by crushing the unborn baby in a frontal crash. NHTSA is denying the petition to regulate the performance of these systems because the agency does not have sufficient information at this time to state whether there is an additional net safety benefit/disbenefit to be derived from their use or whether one type of device is superior to another. NHTSA is denying the petition for labeling because this would provide advice that, if followed, would threaten the safety of both the mother and the unborn child in a crash.
