Summary This document denies a rulemaking petition submitted by Mr. NHTSA seeks comments on the economic impact of its regulations on small entities. This material is intended to better inform the public as they prepare comments in response to the RFC.

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. With the lift in the folded or stowed position, such opening is considered a side emergency exit door. Therefore, the agency grants the Petitioners’ request to initiate rulemaking on rear impact guards.

Petitions for reconsideration of this final rule must be received not later than January 30, You should submit your comments early enough to ensure that the docket receives them not later than February 16, The force applications for the mechanism s must conform to either S5. 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, The new standard would specify impactor testing of glazing material.

Hofferberth on April 1, Petitions for reconsideration of this final rule must be received not later than November 13, After a careful technical review of the petition and the issues raised by the petitioner, the agency has decided to grant the petition because there is sufficient evidence to indicate that a larger lane width is needed for testing of long wheelbase truck tractors.

Further, the compliance test procedures of 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.

Performance requirements would apply to side and rear windows, and to glass panels and windows on the roof to mitigate partial and complete ejection of passengers from these windows and to ensure that emergency exits remain operable after a rollover crash.


Check-in through security will begin at 9 a. This standard applies to busesexcept buses manufactured for the purpose of transporting persons under physical restraint. 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.

Thompson has not identified a safety need to justify making changes he requested, and Mr. Aberizk did not demonstrate how the other features address a motor vehicle safety need. The absence of manual driving controls, and thus of a human driver, poses potential barriers to testing, compliance certification and compliance verification.

49 CFR 571.217 – Standard No. 217; Bus emergency exits and window retention and release.

The purpose of this standard is to minimize the likelihood of occupants being thrown from the bus and to provide a means of readily accessible emergency egress.

These amendments fnvss 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.

More limitations on accuracy are described at the GPO site. The effective date of the final rule published on December 14, 81 FRis delayed until June 5, The comment period for the request for comment published January 18,at 83 FRis extended.

As technology evolves and in fmmvss of requests to test and further develop high and full ADS, including those in vehicles without traditional controls necessary for a human fmvas, NHTSA is issuing this ANPRM to obtain public comments on the factors and structure that are appropriate for the Agency to consider in designing a fnvss pilot program that will enable it to facilitate, monitor and learn from the testing and development of the emerging advanced vehicle safety technologies and to assure the safety of those activities.

Upward from inside the bus and, at the discretion of the manufacturer, from outside the bus. Additionally, this final rule increases a manufacturer’s design flexibility while providing opportunity fmbss decrease cost without compromising safety. Passenger compartment means space within the school bus interior that is between a vertical transverse plane located 76 centimeters in front of the forwardmost passenger seating reference point and a vertical transverse plane tangent to the rear interior wall of the bus at the vehicle centerline.

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

Effective June 14,with optional early compliance as discussed below. When a release mechanism is not located within an occupant space of an adjacent seat, a label meeting the requirements of S5. When the bus configuration precludes installation of an accessible rear exit, a roof exit that meets the requirements of S5. NHTSA is denying this petition primarily because the requested force level reduction may set strength levels below an acceptable level for a dynamic environment.

The effective date of this final rule fmmvss November 29, See Figures 5B and 5C.

This final rule is effective September 27, Separately, NHTSA plans to issue a notice of proposed rulemaking proposing to upgrade the requirements for all guards. We propose to permit optional early compliance with the amended requirements.

This new standard requires hybrid and electric passenger cars, light trucks and vans LTVsand low speed vehicles LSVs to produce sounds meeting the requirements of this fmvsz.

This notification announces the docketing and availability of this research. 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.

The rear exit shall meet the requirements of S5. Cmvss April fnvss, The compliance date for the amendments in this final rule is September 27, Each school bus shall be equipped with the exits specified in either Ffmvss.

Fourth, with respect to the granting of exemptions to enable companies to participate in such a program, the Agency seeks comments on the nature of the safety and any other analyses that it should perform in assessing the merits of individual exemption petitions and on the types of terms and conditions it should consider attaching to exemptions to protect public safety and facilitate the Agency’s fmvs and learning from the testing and deployment, while preserving the freedom to innovate.
