SUPPLEMENTARY INFORMATION:

On May 28, 2026, NHTSA published an RFC notice on a proposal to update NHTSA's NCAP by adding RAB systems with pedestrian avoidance ability to the advanced driver assistance systems technologies NHTSA currently recommends.[1] NHTSA proposed to identify and evaluate vehicles in the marketplace that offer systems that pass NCAP performance requirements for RAB. NHTSA sought comment on its proposal to include RAB in NCAP, including the proposed test procedures and performance criteria. The RFC notice provided a 60-day comment period which closes on July 27, 2026.

On May 29, 2026, NHTSA received a request from Auto Innovators for a 30-day extension of the comment period.[2] Auto Innovators stated that, at the time of its request, the supporting materials referenced in the notice were not available, and that access to these materials is essential to understanding the full scope of the proposal. Auto Innovators stated that a 30-day extension of the comment period would ensure stakeholders have adequate time to review the complete docket and offer substantive and high-quality feedback for the Agency to advance a well-informed update to NCAP.

NHTSA is granting the request to extend the comment period by 30 days. NHTSA has determined that the requestors have shown good cause for an extension and that the extension is consistent with the public interest. A 30-day extension appropriately balances NHTSA's interest in providing the public with sufficient time to comment on the RFC notice and the associated test procedure, with its interest in obtaining specific feedback from stakeholders in a timely manner. Accordingly, NHTSA is extending the comment period until August 26, 2026.[3]

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

Jonathan Morrison,

Administrator.
