Federal Motor Vehicle Safety Standards (FMVSS) Guide

When the vehicle is impacted laterally on either side by a barrier moving at any speed up to and including 20 mph with 50th percentile test dummies as specified in part of this chapter at positions required for testing to Standard No.

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.

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. This document grants the petition for rulemaking submitted by the Truck Safety Coalition, the Center for Auto Safety, Advocates for Highway and Auto Safety, and Road Safe America on February 19,to establish a safety standard to require automatic forward collision avoidance and mitigation systems on certain heavy vehicles.

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.

This document denies a petition for rulemaking submitted by Mr. F,vss isolation between the chassis and the high-voltage system must be maintained at a level of at least ohms per volt. The effective date of this final rule is September 26, Examples of ANSI standards:.

We propose that the compliance date for the amendments in this rulemaking action would be three years following the date of publication of the final rule in the Federal Register. The documents referenced in this notification will be available in the docket as of April 16, The gas pressure shall stabilize to ambient temperature before testing may be conducted.

Previously, the maximum allowable upward mounting angle was 15 degrees beyond vertical.

Electrolyte Spillage and Electric Shock Protection In addition, establishing roof strength and crush resistance requirements, to the extent warranted under the National Traffic and Motor Vehicle Safety Act, would fulfill a statutory provision of the Motorcoach Enhanced Safety Act of incorporated and passed as part of the Moving Ahead for Progress in the 21st Century Act.


Summary This NPRM proposes to upgrade the Federal motor vehicle safety standards that address rear underride protection in crashes into trailers and semitrailers. Each schoolbus with a GVWR greater than 10, pounds that uses CNG as a motor fuel and that is manufactured on or after September 1, shall meet the requirements of S6.

The requirements of S5 and S6 shall be met under the following conditions. Global Automakers petitioned the agency for reconsideration, seeking to correct what it believes is an error in formula for determining the number of designated seating positions in longer seating positions.

The focus of this notice is rules that specifically relate to passenger cars, multipurpose passenger vehicles, trucks, buses, trailers, motorcycles, and motor vehicle equipment. Continued high levels of motorcycle related fatalities, the ongoing use of novelty helmets by motorcyclists and the poor performance of these helmets in tests and crashes have prompted the agency to clarify the status of such helmets under federal law to ensure that all relevant legal requirements are readily enforceable.

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.

You should submit comments early enough to ensure that Docket Management receives them not later than July 30, This document reopens the comment period for a notice of fkvss rulemaking NPRM published January 28, Summary This document denies a petition for rulemaking submitted by Mr. Petitions for reconsideration of this final rule must be received not later than March 24, ANSI is also involved in setting standards for alternative vehicle technology in particular.

Additionally, consumers can purchase their own tool and locate it in the vehicle where they would be likely to access it in an emergency. The agency believes that requiring V2V communication capability in new light vehicles would facilitate the development and introduction of a number of advanced vehicle safety applications.

49 CFR 571.303 – Standard No. 303; Fuel system integrity of compressed natural gas vehicles.

For several years, NHTSA has researched forward collision avoidance and mitigation technology on heavy vehicles, including forward collision warning and automatic emergency braking systems. IEC is an international standards organization. Inwe expect that, without fmvsx 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.

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 fmvsss steering machine.

Based on the petition, available information, and the agency’s analysis in progress, NHTSA has decided that the Petitioners’ request related to rear impact guards merits further consideration. This NPRM proposes rulemaking on these and other requirements to increase the correct use of child restraint anchorage systems and tether anchorages, and the correct use of child restraints, with the ultimate goal of reducing injuries to restrained children in motor vehicle crashes.


United States Code U. The effective date of the final rule published on December 14, 81 FRis delayed until September 5, The proposed FMVSS would also require each vehicle, as manufactured and sold, to have its device set to a speed not greater than a specified speed and to be equipped with means of reading the vehicle’s current speed setting and the two previous speed settings including the time and date the settings were changed through its On-Board Diagnostic connection.

The moving contoured barrier crash test conditions are those specified in S7. Petitions for reconsideration of this final rule must be received not later than November 13, After consideration of the petitions and all supporting information, NHTSA has decided to grant the petitions for four of the discrete changes, deny one, and request comment in a separate document for the sixth proposed change.

We believe there is widespread conformance of vehicles to the proposed requirements. His petition includes two requests: In the absence of a requirement that each vehicle have a glass breaking tool, nothing prevents vehicle manufacturers from providing a tool or other means to allow vehicle evacuation during immersion. When the vehicle is impacted from the rear by a barrier moving at any speed up to and including 30 mph, with test dummies as specified in part of this chapter at each front outboard designated seating positionunder the applicable conditions of S7, the fuel pressure drop shall not exceed the limits of S5.

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 deployment of motor vehicles with high and full driving automation.

This final rule applies to electric vehicles EVs and to those hybrid vehicles HVs that are capable of propulsion in any forward or reverse gear without the vehicle’s fmbss combustion engine ICE operating. More limitations on accuracy are described at the GPO site.

The purpose of this standard is to reduce deaths and injuries occurring from fires that result from fuel leakage during and after motor vehicle crashes.

Summary This document responds to a petition for reconsideration of the agency’s November final rule making amendments to the procedures for cmvss which areas of a vehicle are designated seating positions and the procedure for determining the number of seating positions. Without dmvss 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.
