On December 3, 2020, NHTSA published an ANPRM to obtain public comments on the development of a framework for Automated Driving System (ADS) safety (85 FR 78058). The framework would objectively define, assess, and manage the safety of ADS performance while ensuring the needed flexibility to enable further innovation. The Agency sought specific feedback on key components that can meet the need for motor vehicle safety while enabling innovative designs, in a manner consistent with Agency authorities. The ANPRM provided a 30-day comment period, which closes on February 1, 2021.

On December 18, 2020, NHTSA received a request from Venable LLP on behalf of the Alliance for Automotive Innovation, American Property Casualty Insurance Association, American Trucking Associations, Motor & Equipment Manufacturers Association, National Automotive Dealers Association, National Association of Mutual Insurance Companies, Self-Driving Coalition for Safer Streets, Truck & Engine Manufacturers Association, and the U.S. Chamber of Commerce, Chamber Technology Engagement Center, (hereinafter “the requestors”), for a 60-day extension of the comment period. The requestors state that the ANPRM raises a substantial number of technical and policy questions that require significant discussion and analysis on the part of their respective members. They suggest that an extension would offer them enough time to consult with and seek input from experts across their businesses about the “many complex issues presented in the ANPRM.” They state that having additional time to engage in such consultations would enable them “to better ensure that the comments they provide to NHTSA reflect the full measure of thought and analysis that is due for this important proceeding.” The request can be found in the docket for the ANPRM identified in the heading of this notice.

In accordance with NHTSA's rulemaking procedures in 49 CFR part 553, subpart B, the Agency is granting the request to extend the comment period 60 days. We have determined that the requestors have shown good cause for an extension, and that the extension is consistent with the public interest (49 CFR 553.19). A 60-day extension appropriately balances NHTSA's interest in providing the public with sufficient time to comment on the complex and novel questions raised in the ANPRM, with its interest in obtaining specific feedback from stakeholders in a timely manner. Accordingly, NHTSA is extending the comment period until April 1, 2021.[1]

Authority: 49 U.S.C. 322, 30111, 30115, 30117, and 30166; delegation of authority at 49 CFR 1.95 and 49 CFR 501.5.
