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 fmvs non-over-the-road buses with a gross vehicle weight rating GVWR greater than 11, kilograms kg 26, pounds lb. Optional early compliance as discussed below.

NHTSA will determine fmvsx to issue a rule in the course of the rulemaking proceeding, in accordance with statutory criteria.

Performance requirements would apply to side and rear windows, and to glass panels and windows on 340 roof to mitigate partial and complete ejection of passengers from these windows and to ensure that emergency exits remain operable after a rollover crash. The original comment period closed September 21, Prevost petitioned to revise the seat belt anchorage strength requirements for last row seats having no passenger seating behind them.

The most commonly available alternative fuel for commercial vehicles is natural gas either compressed or liquefied. The focus of this notification is rules that specifically relate to passenger cars, multipurpose passenger vehicles, trucks, buses, trailers, motorcycles, and motor vehicle equipment.

The effective date of this rule is August 24, One exemption will allow Fmvas employee-drivers with commercial driver’s licenses CDLs who transport steel coils between their production and shipping locations on public roads to work up to 16 hours per day and return to work with less than the mandatory 10 fmvas hours off duty. ADS testing and development are already underway in several areas of the United States.

The report’s recommendations were briefed to the 21st Century Truck Partnership on June 19, Based on the petition, available information, fmvs the agency’s analysis in progress, NHTSA has decided that the Petitioners’ request related to rear impact guards merits further consideration.

A review of incidents involving natural gas commercial vehicles has also been completed based on data from the Master List of Natural Gas Vehicles Incidents maintained by the Department of Energy and from the National Fire Incident Reporting System. NHTSA and FMCSA have received requests to extend the comment period for their proposal that would require vehicles with a gross vehicle weight rating of more than 11, This document denies a petition for rulemaking, submitted by Ms.

Summary Currently, there are about 4, heavy-duty trucks, 5, medium-duty trucks, and over 20, transit buses operating on natural gas. Petitions for reconsideration must be received not later than November 10, This document denies a petition for rulemaking submitted by Mr.

Petitions for reconsideration of this final rule must be received by December 27, Period of performance was 15 months. 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.

The incorporation by reference of certain publications listed in the rule is approved by the Director of the Federal Register as of August 24, Petitions for reconsideration of this final action must be received not later than April 12, Fill pressure varies according to the gas temperature in the container which is dependent on the charging parameters and the ambient conditions.

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.

This standard specifies requirements for the integrity of compressed natural gas CNGmotor vehicle fuel containers. The Petitioners’ request to initiate rulemaking on rear impact guards on trailers and single unit trucks is fmvsw on July 10, Position thermocouples so that they are equally spaced over the length of the fire source or length of the container, whichever is shorter.

The first exemption request is for ArcelorMittal’s employee-drivers with commercial driver’s licenses CDLs who transport steel coils vmvss their production and shipping locations on public roads.

The agency requests comments on this alternative strategy and other potential enhancements to the current body block test procedure.

The pressure is increased up to the minimum prescribed burst pressure determined in S7. The initial compliance date is September 1,with full phase in by September 1, The filler metal is distributed between 3304 closely fitted surfaces of the joint by capillary attraction.

Hofferberth on April 1, This document reopens the comment period for a notice of proposed rulemaking NPRM published January 3304, Separately, NHTSA plans to issue a notice of proposed rulemaking proposing to upgrade the requirements for all guards. The effective date of the final rule published on December 14, 81 30is delayed until June 5, Examples of changes needed are labeling of vehicles, height clearance requirements, inspection requirements, training requirements for mechanics, leak detection requirements, and conformance of the FMCSRs to National Fire Protection Association NFPA 52 e.

49 CFR 393.68 – Compressed natural gas fuel containers.

Thompson did not provide persuasive quantitative data to show adopting his requested changes would result in a fmvsw benefit to safety. The comment period for the RFC was originally scheduled to end on March 5, You should submit comments early enough to ensure that Docket Management receives them not later than July 30, A single CNG fuel container is not subjected to more than one bonfire test.

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.

This notice makes corrections to a final rule published in the Federal Register on July 22,regarding amendments to the Federal Motor Carrier Safety Fmss in response to several petitions for rulemaking and NTSB recommendations. 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. We also request comments on ways to make these regulations easier to read and understand.

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.

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 fmvws needed for testing of long wheelbase truck tractors.

Additionally, this final rule increases a manufacturer’s design flexibility while providing opportunity to decrease cost without compromising safety.

This final rule is effective July 22, 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.

Third, the Agency seeks comment on any additional elements of regulatory relief e.
