Federal Motor Vehicle Safety Standards (FMVSS) Guide

Electrical isolation between the chassis and the high-voltage system must be maintained at a level of at least ohms per volt. 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.

Petitions for reconsideration of this final rule must be received not later than March 2, The meeting will start at 10 a. To ensure that all interested parties have a sufficient amount of time to fully develop fmgss 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.

To reduce 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.

After a careful technical review of the petition and the issues raised by the fmves, 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.

The effective date of this final rule is November 29, Full compliance is required on September 1, NHTSA and FMCSA have received requests to extend the comment period for their proposal that fmvxs require vehicles with a gross vehicle weight rating of more than 11, Second, the Fmvsd seeks comments on the use of existing statutory provisions and regulations to allow for the implementation of dmvss a pilot program.

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

The performance requirements would ensure that these vehicles provide a sufficient level of survival space to restrained occupants in rollover crashes. If the vehicle has any high pressure electric shutoff valve that is normally open when the electrical system is activated, it is open at the time of the barrier crash.

Summary This document denies a rulemaking petition submitted by Mr. The compliance date for the amendments in this final rule is September 27, The agency agrees that the change was inadvertent and is issuing this final rule to correct this mistake.


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. NHTSA seeks comment on the research report, and solicits additional information, data, and analysis that will aid the agency in developing an effective proposal to require new light vehicles to be V2V-capable. The data available to the agency shows there is a great deal of uncertainty surrounding the actual number of occupants that may have died due solely to drowning while trapped in an immersed vehicle.

When the moving contoured barrier assembly traveling longitudinally forward at any speed up to and including 30 mph impacts the test vehicle schoolbus with a GVWR exceeding 10, pounds at any point and angle, under the applicable conditions of S7, the fuel pressure drop shall not exceed the limits of S5. The following conditions apply to all tests. The standard includes classifications V-0 the most stringentV-1 and V Petitions for reconsideration of this final rule must be received not later than February 1, This document reopens the comment period for a notice of proposed rulemaking NPRM published January 28, This document denies a rulemaking petition submitted by Mr.

Toyota Motor North America, Inc. The compliance date is September 1,with full phase in by September 1, Relevant standards related to alternative vehicle design are.

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

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.

Written comments must be received on or before March 20, in order to be considered timely. This final rule fmmvss to electric vehicles Fjvss and to those hybrid vehicles HVs that are capable of propulsion in any forward or reverse gear without the vehicle’s internal combustion engine ICE operating. IEC is an international standards organization.

The effective date of the final rule published at 81 FRDecember 14,is delayed until March 21, 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. Any valve shall be open for a period of one minute to equalize the system pressure.

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.


When fmvsx vehicle traveling longitudinally forward at any speed up to and including 30 mph impacts a fixed collision barrier that is perpendicular to the line of travel of the vehicle, or at any angle up to 30 degrees in either direction from the gmvss to the line of travel of the vehicle, with 50th percentile test dummies as specified in part of this chapter 33 each front outboard designated seating position and at any other position whose protection system is required to be tested by a dummy under the provisions of Standard No.

The Petitioners’ request to initiate rulemaking on rear impact guards on trailers and single unit trucks is granted on July 10, 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 fkvss semitrailers.

The barrier fmss test vehicle are positioned so that at ffmvss.

Earlier, NHTSA published an advanced notice of proposed rulemaking requesting comment on strategies pertaining to underride protection afforded by single unit trucks. The Agencies have also received a letter opposing any extension of the comment period. 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.

This NPRM proposes to upgrade the Federal motor vehicle safety standards that address rear underride protection in crashes into trailers and semitrailers. The effective date of this final rule is January 16, NHTSA is denying this petition primarily because the requested force level reduction may set strength levels below an acceptable level for a dynamic environment. ANSI is also involved in setting standards for alternative vehicle technology in particular.

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.

Toyota and the Auto Alliance Alliance. Aberizk did not demonstrate how the other features address a motor vehicle safety need.

His petition includes two requests: The effective date of the final rule published on December 14, 81 FRis delayed until June 5, The lateral moving barrier crash test conditions are those specified in S8. 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.

Attendees should arrive early enough to enable them to go through security by 9:
