Your earlier post suggested that Bahnschrift wasn't yet included but
would be in future. If that is correct then whether it can be embedded
remains to be seen. PowerPoint on windows can embed TrueType fonts, but
only if the flag in the OS/2 table allows it. It sounds like your
project requires editable embedding which is less commonly allowed than
read-only embedding.

Wow. Thanks for those accurate clarifications!

I don't know how to test the embedding on the latest Windows 10 because I
don't have it - but it's great information for the many Windows experts
here that in the "Windows 10 Insider Preview Build 16273", the inclusion of
Bahnschrift DIN-1451-look-alike fonts may or may not be embeddable.

I have included your clarification suggestions in the reference page of the
PowerPoint document for the school, where I reflect those improvements
below as a summary of tribal knowledge for someone reading this in the
future via Dejagoogle links.

Road sign fonts are tested under real-world conditions for specific things
such as halation, night-time and speed legibility (especially when tight
interstices are involved), cutout-integrity, removal of tiny notches in
joints of the letterforms, negative spacing compactness (affecting
legibility of signs in negative-contrast color orientations), common
symbols, etc., all resulting in an increase in accuracy, viewing distance,
and reaction time.

According to this Usenet thread:

The official USA roadsign font is FHWA Series Gothic which isn't
commercially available.
