## Abstract

In July 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 November 2009, the agency published a final rule that provided a partial response to petitions for reconsideration of the earlier rule. Today's document corrects errors in the November 2009 final rule.
