The National Highway Traffic Safety Administration had two rulemakings published in the Federal Register on August 31, 2026: one resetting the agency's fuel economy program for commercial medium- and heavy-duty on-highway vehicles and work trucks, and one extending the comment period on a temporary exemption from motor vehicle safety and bumper standards.

The two actions cover different corners of the commercial vehicle regulatory calendar. The fuel economy reset addresses the program framework for a broad class of working vehicles. The safety and bumper exemption action extends the window for public comment rather than closing it.

The read here is that the comment-period extension signals that record is still open, while the fuel economy action stands as a separate proceeding - though the numbered facts do not specify the rulemaking stage of either action beyond their publication date.

Both items were recorded by the Federal Register instrument as of August 31, 2026. No prior values or obligation figures attach to either action in the available record.
