The U.S. National Highway Traffic Safety Administration (NHTSA) has requested comments on the estimated time and expense burdens of an information collection on motor vehicle traffic crashes through the agency’s National Automotive Sampling System Crashworthiness Data System and Special Crash Investigation programs. Comments must be submitted by July 11, 2014. NHTSA is currently upgrading its data systems “by improving the information technology infrastructure, updating the data we collect and reexamining sample sites.” According to the agency, more data are needed from crashes not currently included in its sampling system, “such as those involving large trucks, motorcycles, and pedestrians.” See Federal Register, May 12, 2014.
