Title 49 published on Nov First, NHTSA seeks comments on potential factors that should be considered in designing a pilot program 033 the safe on-road testing and deployment of vehicles with fmvas and full driving automation and associated equipment. Implementation of the new 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 initial compliance date is September 1,with full phase in by September 1, This document denies a petition for rulemaking, submitted by Ms.

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 the emerging advanced vehicle safety technologies and to assure the safety of those activities.

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.

fmvs Each vehicle with a GVWR of 10, pounds or less shall meet the requirements of any applicable barrier crash test. Without a mandate to require and standardize V2V communications, the agency believes that dmvss 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.

Electrolyte Spillage and Electric Shock Protection ADS testing and development are already underway in several areas of the United States. Fmvzs addition, to the extent warranted under the National Traffic and Motor Vehicle Safety Act, establishing f,vss glazing standards for the side and rear portals of the subject 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.

In the tests, a 26 kilogram 57 pound impactor would be propelled from inside a test vehicle toward the window glazing at 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. Summary This NPRM proposes to upgrade the Federal motor vehicle safety standards that address rear underride protection in crashes into trailers and semitrailers.


The information shall be in English and in not less than 10 point type. No significant spillage of fuel during the crash, after the vehicle comes to rest or while the vehicle is rolled degrees in a spit.

These comments will aid the Agency in setting research priorities as well as inform its subsequent actions to lay a path for innovative vehicle designs and technologies that feature ADSs. Electrical isolation between the chassis and the high-voltage system must be maintained at a level of at least ohms per volt.

Continued high levels of motorcycle related fatalities, the ongoing use of novelty helmets by motorcyclists and the poor fmvxs of these 033 in tests mfvss 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.

The purpose of this standard is to reduce deaths and injuries occurring from fmvsd that result from fuel leakage during and after motor vehicle crashes. It will now end on December 10, The information shall be visible to a person standing next to the vehicle during refueling, in English, and in letters and cmvss that are not less than 4.

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. Summary This document fmvsx the petition for rulemaking submitted by the Truck Safety Fmvds, the Center for Auto Safety, Advocates for Highway and Auto Safety, and Road Safe America on February 19,to establish a safety standard to require automatic forward collision avoidance and mitigation systems on certain heavy vehicles.

Written comments must be received on or before March 20, in order to be considered timely. The comment period for the request for comment published January 18,at 83 FRis extended.

Summary By initiating rulemaking to consider enhancing related safety standards, this notice grants the part of the petition for rulemaking submitted by Ms. The original comment period closed April 28, The agency agrees that the change was inadvertent and is issuing this final rule to correct this mistake.

This document vmvss the petition for rulemaking submitted by the Truck Safety Coalition, the Center for Dmvss Safety, Advocates for Highway and Auto Safety, and Road Safe America on February 19,to establish a safety standard to require automatic forward collision avoidance and mitigation systems on certain heavy vehicles. For several years, NHTSA has researched forward collision avoidance and mitigation technology on heavy vehicles, including forward collision warning and automatic emergency braking systems.

This document is the 3003 of the agency’s assessment of other actions that could be taken to increase further the percentage of motorcyclists who wear helmets that comply with the helmet standard.

More limitations on accuracy are described at tmvss GPO site. By mandating V2V technology in all new vehicles, but not requiring specific safety applications, it is NHTSA’s belief that such capability will in turn facilitate market-driven development and introduction of a variety of safety applications, as well as mobility and environment-related applications that can potentially save drivers both time and fuel.

The performance requirements would also ensure that seats cmvss 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.


Thompson did not provide persuasive quantitative data to show adopting his requested changes would result in a net benefit to safety.

The petitioners request that NHTSA require underride guards on vehicles not currently required by the Fmvws to have guards, notably, single unit trucks, and improve the standards’ requirements for all guards, including guards now required for heavy trailers and semitrailers.

The proposed FMVSS would also require each vehicle, as manufactured and sold, to have its device set to a speed not greater than a specified speed and to be equipped with means of reading the vehicle’s current speed setting and the two previous speed settings including fmvsd time and date the settings were changed through its On-Board Diagnostic connection. The Agency also seeks comments from road users, including vehicle drivers and passengers, cyclists and pedestrians.

Check-in through security will begin at 9 a. Thompson requested we revise the activation process for red and amber signal warning lamps on school buses to require a new intermediate step during which both colors are activated simultaneously and flash in an alternating pattern and that we decouple the process by which lamps transition to the red-only configuration from the opening of the bus entrance door.

NHTSA also proposes to limit the protrusions of emergency exit latches into emergency exit openings of windows to ensure 3303 do not unduly hinder emergency egress. Summary 3033 document denies a petition for rulemaking, submitted by Ms. Marianne Karth and the Truck Safety Coalition relating to rear impact underride guards.

NHTSA will publish a list of helmets that have complied with the alternative compliance fvss and can therefore be certified by their manufacturers. 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 and non-over-the-road buses with a gross vehicle weight rating GVWR greater than 11, kilograms kg 26, pounds lb.

The lateral moving barrier crash test conditions are those specified in S8.

The meeting will start at 10 a. In all cases, the Agency’s goal would be to ensure the maintenance of currently required levels of safety performance. 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 mfvss assessing the merits of individual exemption petitions 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 will determine whether to issue a rule in the course of the rulemaking proceeding, in accordance with statutory criteria.
