Special Crash Investigations



Air Bag Investigations


More than 1,200 air bag investigations have been conducted to date, about 50 per year.  The SCI program established a census of the early air bag vehicle crashes which played a pivotal role in the establishment of Federal Motor Vehicle Safety Standard 208.   Due to the rapid growth of air bag equipped vehicles into the marketplace in 1988, the program shifted gears from investigation of each air bag vehicle crash to investigating special interest cases involving such issues as non-deployment crashes, air bag related injuries, interaction with child safety seats, and new air bag equipped vehicles crashes.  These SCI air bag cases have been utilized by the agency and the automotive safety community to understand the real world performance of their state-of-the-art systems, and have been instrumental in influencing subsequent changes to a number of production air bag systems.

Summary tables  of air bag related fatalities and injuries are available.


School Bus Investigations


Thirty-nine school bus crash investigations have been conducted to date. Included in this count are incidents of children being killed or injured as they enter or exit the loading zone.  These cases are a useful tool to NHTSA in assessing the real world performance of conventional, transit, and van-based school bus crashworthiness and crash avoidance issues.   Such issues have included mirror systems, hand rail designs, video monitoring of pupils, safety belt use, and joint strength.


New and Emerging Technologies


The SCI program's flexibility allows for the detailed investigation of any new emerging technologies related to automotive safety.  A number of incidents involving alternative fuel vehicles, passenger side air bag deployments, vehicle-to-pedestrian impacts, and child safety restraints have been investigated.  As was the case with the early SCI air bag investigations, these anecdotal investigations will be utilized by NHTSA and the automotive safety community to understand the real world performance of these state-of-the-art systems, and will result in increased safety from subsequent second and third generation improvements to these new technologies.
