Docket No. NHTSA 99-5045
Abstract
NHTSA is amending its air brake standard to correct an inconsistency between two provisions concerning emergency brake stops, provide that single-unit truck axles should not be overloaded, clarify the wheel-lock provisions by adding a definition of Atandem axle," and to permit the use of roll bars on vehicles undergoing brake testing. This rulemaking was initiated in response to a petition for rulemaking from the Truck Manufacturers Association.
