Air Brake Rule Takes Effect November 24

The National Highway Traffic Safety Administration has responded to petitions for reconsideration regarding this past summer’s rule calling for reduced stopping distances for air-braked tractors.

In a final rule appearing in the November 13 Federal Register, the agency announced a partial response to petitions for reconsideration. The final rule 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.
