Department of Transportation November 9, 2021 – Federal Register Recent Federal Regulation Documents

This amendment adopts miscellaneous amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas.

FMCSA amends the Federal Motor Carrier Safety Regulations (FMCSRs) to include rear impact guards on the list of items that must be examined as part of the required annual inspection for each commercial motor vehicle (CMV). In addition, FMCSA amends the labeling requirements for rear impact guards, and excludes road construction controlled (RCC) horizontal discharge trailers from the rear impact guard requirements, consistent with changes made by the National Highway Traffic Safety Administration (NHTSA) to the corresponding Federal Motor Vehicle Safety Standards (FMVSS). This final rule responds to rulemaking petitions, as well as a recommendation from the Government Accountability Office (GAO).
