The effective date 34 the final rule published at 81 FRDecember 14,is delayed until March 21, 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.


Optional early compliance is permitted. Petitions for reconsideration of this final rule must be received not later than January 30, Petitions for reconsideration of this final rule must be received not later than March 24, Summary By initiating rulemaking to consider enhancing related safety standards, this notice grants the part of the petition for rulemaking submitted by Ms.

Accordingly, we propose that the compliance date for the amendments in this rulemaking action would be days after the date of publication of the final rule in the Federal Register.

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 Agency makes minor changes to correct inadvertent errors and omissions, remove or update obsolete references, ensure conformity with Office of the Federal Register style guidelines, and improve the clarity and consistency of certain regulatory provisions.

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 change.

We propose that the compliance date for the amendments in this rulemaking action would be three years following the date of publication of the final rule in the Federal Register. The initial compliance date is September 1,with full phase in by September 1, 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 the time and date the settings were changed through its On-Board Diagnostic connection.


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.

49 CFR 393.68 – Compressed natural gas fuel containers.

Petitions for Reconsideration must be received fmvvss the Agency no later than August 22, 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.

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 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.
