Washington, DC–(ENEWSPF)–December 16, 2011. Despite an overall downward trend in transportation fatalities in the United States, estimates for 2010 released by the National Transportation Safety Board (NTSB) today reveal a rise in several categories, including motorcycles, medium and heavy trucks, buses, rail and pipeline. The deadly natural gas pipeline accident in San Bruno, California, that killed eight people and was investigated by the NTSB, contributed to the rise in pipeline fatalities.
