We believe that, by requiring that ESC systems be installed on the rest of truck tractors and large buses, this final rule will prevent 40 to 56 percent of untripped rollover crashes and 14 percent of loss-of-control crashes. NHTSA is denying the petition for labeling because this would provide advice that, if followed, would threaten the safety of both the fmvss a regulation and the unborn child in a crash.


When measured in accordance with S5. In each vehicle other than a school busa head restraint that conforms to either S4.

Applying a load of no more than 5 N along the axis of the cylinder, place the fmvse against any gap within the area of measurement specified in subparagraph a. The original comment period closed September 21, Summary This document denies a petition for rulemaking, submitted by Ms. The effective date of this rule is August 24, Remove or rigidly secure the engine, transmission, axles, exhaust, vehicle frame and any other vehicle component necessary to assure that all points on the acceleration vs.

The incorporation by reference of certain publications listed in the rule is approved by the Director of the Federal Register as of August 24, As technology evolves and in anticipation of requests to test and further develop high and full ADS, including those in vehicles without traditional controls necessary for a human driver, NHTSA is issuing this ANPRM to obtain public comments on the factors and structure that are appropriate for the Agency to consider in designing a national pilot program that will enable it to facilitate, monitor and learn from the testing and development of fmvds emerging advanced vehicle safety technologies and to assure the safety of those activities.

These amendments will restore the side marker photometry requirements for motor vehicles under thirty feet in length 202 were in place prior to the final rule that reorganized the standard.

The focus of this notification is rules that specifically relate to passenger cars, multipurpose passenger vehicles, trucks, buses, trailers, motorcycles, and motor vehicle equipment.


This standard will help to ensure that blind, visually impaired, and other pedestrians are able to detect and recognize nearby hybrid 20a electric vehicles, as required by the PSEA. Adjust the seat cushion and seat back as required by S5 of this section. All head restraints must meet limits for gaps in the head restraint specified in S4. We propose to permit optional early compliance with the amended requirements.

FMVSS 202a

The agency agrees that the change was inadvertent and is issuing this final rule to correct this mistake. When the head restraint is tested in accordance with S5. Written comments must be received on or before March 20, in order to be considered timely. At each forward-facing outboard designated seating position equipped with a head restraintthe head restraint adjusted midway between the lowest and the highest position of adjustmentand at any revulation of backset adjustmentmust conform to fmvss a regulation following:.

Fmvss a regulation the top of the head restraintin its lowest position of adjustmentis above mm, the requirements of this section must be met at that position. V2V begins to 2202a 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.

This document denies a petition for rulemaking, f,vss by Ms. Separately, NHTSA plans to issue a notice of proposed rulemaking proposing to upgrade the requirements for all guards. The following seat adjustments specify conditions to be met concurrently and are not a sequential list of adjustments.

The agency will continue to conduct research and to evaluate real-world performance of these systems through track testing and field operational testing. National Highway Traffic Safety Administration.

Backset means the minimum horizontal distance between the rear of a representation of the head of a seated 50th percentile male occupant and the 2002a restraintas measured by the head restraint measurement device. A rear head restraint may be adjusted to a position at which its height does not comply with the requirements of S4. Apply the force vector normal to the torso reference line and maintain it within 2 degrees of a vertical plane parallel to the vehicle longitudinal centerline.

This notification announces the fmvsss and availability of this research.

InterRegs: 49 CFR Part a (FMVSS a) | US – Federal

This final rule is effective September 27, If there is more than one inclination position closest to the design angle, set the seat back inclination to the position closest to and rearward of the design angle. You should submit your comments early enough to ensure that the docket receives them not later than September 21, In those instances in which this head restraint cannot attain the required heightwhen measured in accordance with S5.


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 2002a. However, the standard’s requirements for rear head restraints do not apply to vehicles manufactured before September 1,and, for vehicles manufactured between September 1, and August 31,the requirements for rear head restraints apply 22a to the extent provided in S7.

Second, the Agency seeks comments on the use of existing statutory provisions and regulations to allow for the implementation of such a pilot program. ESC systems in truck tractors and large buses are designed to reduce untripped rollovers and mitigate severe understeer or oversteer conditions that lead to loss of control by using automatic computer-controlled braking and reducing engine torque output.

The report also explores technical, legal, security, and privacy issues related to the implementation of V2V. 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.

No data generated after ms from the beginning of the forward acceleration are used in determining HIC. If the head restraint is adjustable, adjust the top of the head restraint to a position midway fmbss the lowest position of adjustment and the highest 2002a of adjustment. Position the midpoint of the bottom surface of the cylinder in contact with the head restraint. Marianne Karth and the Truck Safety Coalition relating to rear impact underride guards.

This final rule denies most aspects of a petition for reconsideration of a February 27,final rule that expanded the applicability of the Federal motor vehicle safety standard for child restraint systems to child fmvss a regulation sold for children weighing up 202x 36 kilograms kg 80 pounds lb.

Earlier, NHTSA published an advanced notice of proposed rulemaking requesting comment on strategies pertaining to underride protection afforded by single unit trucks.

Rear head restraint means, at any rear outboard designated seating positiona rear seat back, or any independently adjustable seat component attached to or adjacent to a seat back, that has a height equal to or greater than mm, in any position of backset and height adjustmentas measured in accordance with S5.
