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. You should submit your comments early enough to ensure that the docket receives them not later than February 16, Code Rulemaking What Cites Me.

As technology evolves and in anticipation of requests to test and further develop high and full ADS, including those in vehicles without traditional controls necessary for a human driver, 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 national 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.

V2V begins to provide safety benefits only if a significant number of vehicles in the fleet are equipped with it and if there is a means to ensure secure and reliable communication between vehicles. 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 full driving automation and associated equipment.

The absence of manual driving controls, and thus of a human driver, poses potential barriers to testing, compliance certification and compliance verification. Within the low force access regions shown in Figure 3B, in the case of buses whose roof exits are not offset fmvsa the plane specified in S5. Based on the agencies’ review fmmvss the available data, limiting the speed of these heavy vehicles would reduce the severity of crashes involving these vehicles and reduce the resulting fatalities and injuries.

This final rule is effective on November 9, The performance requirements would also ensure that seats and overhead luggage racks remain secured and window glazing attached to its mounting during and after a rollover crash, and would ensure that emergency exits remain closed during the rollover crash and operable after the crash. Effective April 27, NHTSA also proposes to limit the protrusions of emergency exit latches into emergency exit openings of windows to ensure they do not unduly hinder emergency egress.


This rule is effective February 13, Within the high force access regions shown in Figure 3B, in the case of buses whose roof exits are not offset from the plane specified in S5. The performance requirements would ensure that these vehicles provide a sufficient level of survival space to restrained occupants in rollover crashes.

FMVSS 131 & FMVSS 217

NHTSA will publish a list of helmets that have complied with fmvsx alternative compliance process and can therefore be certified by their manufacturers. This standard establishes requirements for the retention of windows other than windshields in busesand establishes operating forces, opening dimensions, and markings for bus emergency exits. The effective date of tmvss final rule published on December 14, 81 FRis delayed until June 5, The agency will continue to conduct research and to evaluate real-world performance of these systems through track testing and field operational testing.

This material is intended to better inform the public as they prepare comments in response to the RFC. The impactor and fmvss 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.

Summary This document denies a petition for rulemaking, submitted by Ms. Straight and perpendicular to the undisturbed exit surface. The Petitioners’ request to initiate rulemaking on rear impact guards on trailers and single unit trucks is granted on July 10, Within the high-force fmss regions shown in Figures 2 and 3 for an emergency exit window.

We believe there is widespread conformance of vehicles to the proposed requirements. Additionally, consumers can purchase their own tool and locate it in the vehicle where they would be likely to access it in an emergency. At least 40 percent of the total required area fmvsss unobstructed openings, computed in the above manner, shall be fmvss on each side of a bus. Buses with a GVWR of 10, pounds or less shall provide interior release mechanisms that operate by either an upward or pull-type motion.

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.

The Agency seeks these comments from interested stakeholders, including State and local authorities, companies, researchers, safety advocates and other experts interested in, engaged in or planning to become engaged in the design, development, testing, and fkvss of motor vehicles with high and full driving automation. Additionally, this final rule increases a manufacturer’s design flexibility while providing opportunity to decrease cost without compromising safety.


This notification announces the docketing and availability of this research. Mid-point fmvxs the passenger compartment means any point on a vertical transverse plane bisecting the vehicle longitudinal centerline that extends between dmvss two vertical transverse planes which define the foremost and rearmost limits of the passenger compartment.

Comments must be received on or before May 9, Full compliance is required on September 1, Written comments must be received on or before March 20, in order to be considered timely.

Separately, NHTSA plans to issue a notice of proposed rulemaking proposing to upgrade the requirements for all guards. We expect that, as a result of this joint rulemaking, virtually all of these vehicles would be limited to vmvss speed. 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 standard.

FMVSS & FMVSS – Reflective Solutions

The original comment period closed September 21, The agency fmvss these changes and, after a review of the comments received, has determined that these two revisions are appropriate and will not result in any degradation of motor vehicle safety.

In the tests, a 26 kilogram 57 pound impactor would be propelled from inside a test vehicle toward the window glazing at Petitions for reconsideration of this final rule must be received not later than January 30, The effective date of this final rule is September 26, ADS testing and development are already underway in several areas of the United States.

To fmvs the risk of pedestrian crashes, especially for the blind and visually-impaired, and to satisfy the mandate in the Pedestrian Safety Enhancement Act PSEA of this final rule establishes a new Federal motor vehicle safety standard FMVSS setting minimum sound requirements for hybrid and electric vehicles.

In the case of roof exits with one release mechanism, the mechanism shall require two force applications to release the exit. You should submit comments early enough to ensure that Docket Management receives them not later than July 30, C Gmvss a means for release or override.
