I've found this undocumented tag, used 130,000 times, almost
exclusively in the USA.

https://taginfo.openstreetmap.org/keys/hgv%3Anational_network#overview

Values: yes 86.56%   terminal_access 13.37%

I thought it might be imported from Tiger, but the usage has increased
gradually since 2012: 60k more ways have been tagged in that time.

How are these tags being used?

I'm guessing that hgv:national_network=yes means that a road is
designated for heavy trucks to use for long-distance trips.

Perhaps hgv:national_network=terminal_access means that heavy trucks
can only use a road if their destination is on it, or near it?
