Inwe expect that, without this rule, about 34 percent of new truck tractors and 80 percent of new buses affected by this final rule would be equipped with ESC systems. The petitioners request that NHTSA require underride guards on vehicles not currently required by the FMVSSs to have guards, notably, single unit trucks, and improve the standards’ requirements for all guards, including guards now required for heavy trailers and semitrailers.

NHTSA and FMCSA have received requests to extend the comment period for their proposal that would require vehicles with a gross vehicle weight rating of more than 11, ESC systems in truck tractors and large buses are designed to reduce untripped rollovers and mitigate severe understeer or oversteer conditions that lead to loss of control by using automatic computer-controlled braking and reducing engine torque output. NHTSA is issuing this NPRM to propose a new Federal motor vehicle safety standard to enhance the rollover structural integrity of certain types of large buses generally, over-the-road buses of any weight and non-over-the-road buses with a gross vehicle weight rating GVWR greater than 11, kilograms kg 26, pounds lb.

Except as provided in S5. By initiating rulemaking to consider enhancing related safety standards, this notice grants the part of the petition for rulemaking submitted by Ms.

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. The meeting will start at 10 a. 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.


Petitions for reconsideration of this final rule must be received not later than December 14, The impactor and impact speed would simulate the loading from an average size unrestrained adult male impacting a window on the opposite side of a large bus in a rollover.

Not more than newtons. NHTSA is denying the petition for labeling because this would provide advice that, if followed, would threaten the safety of both the mother and the unborn child in a crash. As shown in Figure 2 or Figure 3. First, NHTSA seeks comments on potential factors that should be considered in designing a pilot program for the safe on-road testing and deployment of vehicles with high and fmvzs driving automation and associated equipment. These instructions shall be in letters at least 1 centimeter high and of a color that contrasts with its background.

For emergency window exits, the designation shall be located at the top of, or directly above, or at the bottom of the emergency window exit on both the inside and outside surfaces of the bus.

Within the high force access region shown in Figure 3A for a side emergency exit door, within the high force access region shown in both Figure 3D 1 and Figure 3D 2 for an interior release mechanism for a rear emergency exit door, and within the high force access region shown in Figure 3D 1 for an exterior release mechanism for a rear emergency exit door.

Aberizk did not demonstrate how the other features address a motor vehicle safety need.

Effective Fmvvss 14,with optional early compliance as discussed below. Without a mandate to require and standardize V2V communications, the agency believes that manufacturers will not be able to move forward in an efficient way and that a critical mass of equipped vehicles would take many years to develop, if ever.

Wheelchair means a wheeled seat frame for the support and conveyance of a physically disabled person, comprising at least a frame, seat, and wheels. NHTSA seeks comments on the economic impact of its regulations on small entities.

The incorporation by reference of certain publications listed in the rule is approved by the Director of the Federal Register as of August 24, Prevost petitioned to revise the seat belt anchorage strength requirements for last row seats having no passenger seating behind them.

Each school bus shall be equipped with the exits specified in either S5. As required by Section of the Regulatory Flexibility Act, we are attempting to identify rules that may have a significant economic impact on a substantial number of small entities. The agency believes that requiring V2V communication capability in new light vehicles would facilitate fmvs development and introduction of a number of advanced vehicle safety fmvsd.

The Agency also seeks comments from road users, including vehicle drivers and passengers, cyclists and pedestrians. 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 fkvss the exit.

This final rule increases harmonization with existing requirements in European regulations. Summary This document denies a petition for rulemaking, submitted by Ms. The agency requests comments on this alternative strategy and other potential enhancements to the current body block test procedure.

This will fmvs an information environment in which vehicle and device manufacturers can create and implement applications to improve safety, mobility, and the environment.

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.

B Keeps the door from closing past the point at which the door is perpendicular to the side of the bus bodyregardless of the body’s orientation; and.

The agency is proposing performance requirements that new large buses of these types must meet in a test fkvss which the vehicle is tipped over from an millimeter mm raised platform onto a level ground surface.
