National Highway Traffic Safety Administration November 13, 2009 – Federal Register Recent Federal Regulation Documents

On July 27, 2009, NHTSA published a final rule that amended the Federal motor vehicle safety standard for air brake systems by requiring substantial improvements in stopping distance performance. In response, the agency received eight petitions for reconsideration. This document responds to those petitions by correcting errors in a table published in the final rule, removing a testing specification, and adjusting the compliance date for a small number of vehicles the agency had not fully accounted for in the final rule. This document provides a partial response to the submitted petitions for reconsideration.
