Federal Motor Vehicle Safety Standards; Air Brake Systems Control Line Pressure Balance

Riepilogo

On July 13, 1994, NHTSA published in the Federal Register a notice of proposed rulemaking for an amendment of the control line pressure differential requirements in Standard No. 121, Air Brake Systems, for converter dollies and trailers designed to tow another vehicle equipped with air brakes. (59 FR 35672) It has come to the agency's attention that the section titled ``PART 571--[AMENDED]'' contains several errors. This notice serves to correct that section.
