NHTSA also seeks comments on the research that would be needed to determine how to amend the FMVSS in order to remove such barriers, while retaining those existing safety requirements that will be needed and appropriate for those vehicles.

To ensure that all interested parties have a sufficient amount of time to fully develop their comments, the Agencies are extending the deadline for the submission of written comments on the proposal, including comments on the Preliminary Regulatory Impact Analysis and Initial Regulatory Flexibility Analysis and Draft Environmental Assessment accompanying the proposal, by 30 days. Effective June 14,with optional early compliance as discussed below. Public comments are welcome at this meeting, but all should be oral, and any supporting presentations or materials should be submitted to the docket for consideration.

NHTSA is planning on issuing two separate notices—an advanced notice of proposed rulemaking pertaining to rear impact guards and other safety strategies for single unit trucks, and a notice of proposed rulemaking focusing on rear impact guards on trailers and semitrailers.

Petitions for reconsideration of this final rule must be received not later than November 13, Comments must be received on or before May 9, Not more than 89 newtons. See Figures 5B and 5C. For several fmvsa, NHTSA has researched forward collision avoidance and mitigation technology on heavy vehicles, including forward collision warning and automatic emergency braking systems. This will create an information environment in which vehicle and device manufacturers can create and implement applications to improve safety, mobility, and the environment.


USA – Correction of FMVSS 217 bus emergency exits and window retention and release

Each school bus shall be equipped with the exits specified in either S5. Daylight opening means the maximum unobstructed opening of an emergency exit when viewed from a direction perpendicular to the plane of the opening.

School buses shall not be equipped with horizontally-sliding emergency exit windows. Further, the compliance test procedures mfvss some FMVSS depend on the presence of such things as a human test driver who can follow instructions on test driving maneuvers or a steering wheel that can be used by an automated steering machine.

NHTSA will determine whether to issue a rule in the course of the rulemaking proceeding, in accordance with statutory criteria. In the case of windows with one release mechanism, the mechanism shall require two force applications to release the exit. Wheelchair means a wheeled fmmvss frame for the support and fmves of a physically disabled person, comprising at least a fmvas, seat, and wheels.

These requirements and the associated test procedures would identify those helmets whose physical characteristics indicate that they likely cannot meet the existing performance requirements of the standard. Third, we are incorporating an optional alternative compliance process for manufacturers whose helmets do not comply with the proposed dimensional and compression requirements, but do comply with the performance requirements and all other aspects of FMVSS No. Both of those applications address intersection crashes, which are among the most deadly crashes that U.

In the case of buses which have roof exits offset from the plane specified in S5. After the release mechanism has been operated, each emergency roof exit of a school bus shall, under the conditions of S6, before and after the window retention test required by S5. Each release mechanism shall operate without the use of remote controls or tools, and notwithstanding any failure of the vehicle’s power system.


This standard applies to busesexcept buses manufactured for the purpose of transporting persons under physical restraint. The documents referenced in this notification will be available in the docket as of April 16, This rule is effective February 13, When the bus configuration precludes installation of an accessible rear exit, a roof exit that meets the requirements of S5. Marianne Karth and the Truck Safety Coalition relating to rear impact underride guards.

The effective date of the final rule published on December 14, 81 FRis delayed until June 5, C Provides a means for release or override. Toyota and the Auto Alliance Alliance.

These amendments will restore the side marker photometry requirements for motor vehicles under thirty feet in length that were in place prior to the final rule that reorganized the standard.

This NPRM proposes to upgrade the Federal motor vehicle safety standards that address rear underride protection in crashes into trailers and semitrailers. After consideration of the petitions and all supporting information, NHTSA has decided to grant the petitions for four of the discrete fmcss, deny one, and request comment in a separate document for the sixth proposed change. Dmvss initiating rulemaking to consider enhancing related safety standards, this notice grants the part of the petition for rulemaking submitted by Ms.

The force application for the release mechanism must differ by not less than 90 degrees and not more than degrees from the direction of the initial motion to open the exit.

The incorporation by reference of certain publications listed in the proposed rule is approved by the Director of the Federal Register as of May 22, It is not guaranteed to be accurate or up-to-date, though we do refresh the database weekly.
