Event Data Recorders

This final rule specifies uniform requirements for the accuracy, collection, storage, survivability, and retrievability of onboard motor vehicle crash event data in passenger cars and other light vehicles equipped with event data recorders (EDRs). This final rule responds to the growing practice in the motor vehicle industry of voluntarily installing EDRs in an increasing number of light vehicles. This final rule is intended to standardize the data obtained through EDRs so that such data may be put to the most effective future use and to ensure that EDR infrastructure develops in such a way as to speed medical assistance through providing a foundation for automatic crash notification (ACN). This final regulation: requires that the EDRs installed in light vehicles record a minimum set of specified data elements; standardizes the format in which those data are recorded; helps to ensure the crash survivability of an EDR and its data by requiring that the EDR function during and after the front and side vehicle crash tests specified in two Federal motor vehicle safety standards; and requires vehicle manufacturers to ensure the commercial availability of the tools necessary to enable crash investigators to retrieve data from the EDR. In addition, to ensure public awareness of EDRs, the regulation also requires vehicle manufacturers to include a standardized statement in the owner's manual indicating that the vehicle is equipped with an EDR and describing the functions and capabilities of EDRs. This final rule for standardization of EDR data will ensure that EDRs record, in a readily usable manner, the data necessary for ACN, effective crash investigations, and analysis of safety equipment performance. Standardization of EDR data will facilitate development of ACN, e-911, and similar systems, which could lead to future safety enhancements. In addition, analysis of EDR data can contribute to safer vehicle designs and a better understanding of the circumstances and causatio
