Summary This NPRM proposes to upgrade the Federal motor vehicle safety standards that address rear underride protection in crashes into trailers and semitrailers. This document denies a rulemaking petition submitted by Mr.

United States Code U. Implementation of the dmvss standard will enable vehicle manufacturers to develop safety applications that employ V2V communications as an input, two of which are estimated to prevent hundreds of thousands of crashes and prevent over one thousand fatalities annually.

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 from an millimeter mm raised platform onto a level ground surface.

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. Petitions for reconsideration of this final rule must be received not later than March 24, 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.

The initial compliance date is September 1,with full phase in by September 1, 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.


Relevant standards related to alternative vehicle design are. Summary 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.

Thompson did not provide persuasive quantitative data to show adopting his requested changes would result in a net benefit to safety. In all cases, the Agency’s goal would be to ensure the maintenance of currently required levels of safety performance. Each schoolbus with a GVWR greater than f,vss, pounds that uses CNG as a motor fuel and that is manufactured on or after September 1, shall meet the requirements of S6.

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 requirements of S5 and S6 shall be met under the following conditions.

Furthermore, if any electric shutoff valve prevents sensing of system pressure by the pressure transducer when closed, it must be open for both the initial pressure measurement and the pressure measurement 60 minutes after the vehicle ceases motion from impact. You should submit your comments to ensure that Docket Management receives them not later than July 20, The Agency also seeks comments from road users, including vehicle drivers and passengers, cyclists and pedestrians.

You should submit comments early enough to ensure that Docket Management receives them not later than March 24, No significant spillage of fuel during the crash, after the vehicle comes to rest or while the vehicle is rolled degrees in a spit.

Summary 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 fmvws and non-over-the-road buses with a gross vehicle weight rating GVWR greater than 11, kilograms kg 26, pounds lb.

As of March 21,the effective date of the final rule published on December 14, 81 FRdelayed on February 6, 82 FRis further delayed until May 22, This final rule is effective September 27, When the vehicle is impacted from the rear by a barrier moving at any speed up to and including 30 mph, with fmvsx 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.


Optional early compliance is permitted. Summary This document denies a petition for rulemaking submitted by Mr.

More limitations on accuracy are described at the GPO site. A flame is applied to a polymer sample for each of the UL 94 tests; specimens are then observed for the extent and rate of fire propagation. This final rule increases harmonization with existing requirements in European regulations.

In addition, to the extent warranted under the National Traffic and Motor Vehicle Safety Act, establishing advanced glazing standards for the side and rear portals of the fmvse buses 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.

Petitions for reconsideration of this final rule must be received not later than February 1, 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 fvss focusing on rear impact guards on trailers and semitrailers.

Today’s proposal would facilitate the introduction of new technologies including hydrogen fuel cell vehicles and 48 volt mild hybrid technologies, and responds not only to GTR No.

Electrical isolation between the chassis and the high-voltage system must be maintained at a level of at least ohms per volt. Additionally, this final rule increases a manufacturer’s design flexibility while providing opportunity to decrease cost without 033 safety.
