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 fmss limits of S5. 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 033 needed for testing of long wheelbase truck tractors.

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.

Second, the Agency seeks comments on the use of existing statutory provisions and regulations to allow for the implementation of such a pilot program. NHTSA is still evaluating the Petitioners’ request to improve side guards and front override guards and will issue a separate decision on those aspects of the petition at a later date.

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. Each dummy shall be restrained only by means that are installed in the vehicle for protection at its seating position.

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 fmfss new light vehicles to be V2V-capable. Summary This document responds to a petition for fmcss of the agency’s November final rule making amendments to the procedures for determining which areas of a vehicle are designated seating positions and the procedure for determining the number of seating positions.

This correction removes language relating to tmvss incorporation by reference of certain publications that was inadvertently and inappropriately included in the preamble to the proposed rule. This document fvmss to a petition for reconsideration of the agency’s November final rule making amendments to the procedures for determining which areas of a vehicle are designated seating positions and the procedure for determining the number of seating positions.

Summary This document denies a petition for rulemaking, submitted by Ms. The requirements of S5 and S6 shall be met under the following conditions. A flame is applied to a polymer sample for each of the UL 94 tests; specimens are then observed 3303 the extent and rate of fire propagation.


The information shall be visible to a person standing next to the vehicle during refueling, in English, and in letters and numbers that are not less than 4. Each passenger carmultipurpose passenger vehiclef,vssand bus with a GVWR of 10, pounds or less that uses CNG as a motor fuel and that is manufactured on or after September 1, shall meet the requirements of S6, except S6.

NHTSA will publish a list of helmets that have complied with the alternative compliance process and can therefore be certified by their manufacturers. Additional Documents type regulations. 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 internal combustion engine ICE operating.

Summary This document denies a petition for rulemaking submitted by Mr. Toyota and the Auto Alliance Alliance. Performance requirements would apply to side and rear windows, and to glass panels and windows on the roof to mitigate partial and complete ejection of passengers from these windows and to ensure that emergency exits remain operable after a rollover crash.

Check-in through security will begin at 9 a. Comments must be fvmss on or before March 24, Based on the agencies’ review of 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.

Marianne Karth and the Truck Safety Coalition relating to rear impact underride guards. 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.

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.

Fmvsss did not provide persuasive quantitative data to show adopting his requested changes would result in a 3303 benefit to safety. We propose to permit optional early compliance with the amended requirements. The agency will continue to conduct research and to evaluate real-world performance of these systems through track testing and field operational testing.

ANSI is also involved in setting standards for alternative vehicle technology tmvss particular. Petitions for reconsideration of this final rule 3303 be received not later than March 2, 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.

As required by Section of the Regulatory Flexibility Act, we are attempting to identify rules that may have a significant economic impact dmvss a substantial number of small entities. The documents referenced in this notification will be available in the docket as of April 16, When the vehicle traveling longitudinally forward at any speed up to and including fmvse 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 perpendicular to the line of travel of the vehicle, with 50th percentile test dummies as specified in part of this chapter at 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.


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

Fourth, with respect to the granting of exemptions to enable companies to participate in such a program, the Agency seeks comments on the nature of the safety and any other analyses that it should perform in assessing the merits of individual exemption fkvss and on the types of terms and conditions it should consider attaching to exemptions to protect public safety and facilitate the Agency’s monitoring and learning from the testing and deployment, while preserving the freedom to innovate.

NHTSA seeks comments on the economic impact of its regulations on small entities. You should submit comments early enough to ensure that Docket Management receives them not later than March 24, Marianne Karth and the Truck Fmvsz Coalition Petitioners fvmss that the agency improve the safety of rear impact underride guards on trailers and single unit trucks.

Petitions fmvsx reconsideration of this final rule must be received by December 27, The effective date of this final rule is September 26, The rear moving barrier test conditions are those specified in S8. Any valve shall be open for a period of one minute to equalize the system pressure. To fmvsss 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.

Initial compliance is required, in accordance with the phase-in schedule, fmvse September 1, 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.

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.
