Andrew beat me to it.
There is a speed restriction associated with the "Must use low gear
signs" under the road rules.
It states:
"you must drive in a gear that is low enough to limit the speed of your
vehicle without using the foot brake."
Unfortunately it's not a defined limit although in places there may be a
speed limit sign for trucks and buses as well. eg on the Great Eastern
Freeway heading towards Perth.

Good point. If it's a restriction, it should be more like the maxspeed
tag, maxspeed:hgv=*
So something like low_gears:hgv=designated rather than using the
hazard key.

Just one thought on this:
The "use low gears" it not itself the hazard. It is the steep hill
that is the hazard (where the mitigation strategy for HGVs is to
use low gears. Same for rollover/sharp bend.

Thank You Greame,
The
https://wiki.openstreetmap.org/wiki/Key:hazard#Traffic_hazards tag
seems very appropriate but in my mind, needs a :hgv namespace.
still not sure on the actual values but...tag/values I would
appreciate feedback on:
hazard:hgv=Use low gears
hazard:hgv=Long Steep Descent
hazard:hgv=Use low gears;Long Steep Descent
Another example I would appreciate feedback are QLD "Tilting
Truck signs":
https://www.qld.gov.au/transport/safety/signs/warning
hazard:hgv=Tilting
hazard:hgv=High Risk Rollover
hazard:hgv= ?????????????
Kind regards,
Andrew

There are other signage like "No Engine Breaking",
could anyone propose a convention inline with the
above that could be extended for such additional signage?
Answering in reverse!
I thought I remembered something about "quiet zones" for
traffic, so did some searching & found:
https://wiki.openstreetmap.org/wiki/Talk:Tag:railway%3Dlevel_crossing#Quiet_zones,
but which has apparently never been used.
Also found
https://wiki.openstreetmap.org/wiki/Key:designation#Quiet_lanes
The same idea could possibly be used as
designation=quiet_zone, possibly with quiet_zone=hgv?
Can anyone suggest the most appropriate way to take
ways where the road is signed with "Use Low Gears"?
& maybe the same concept as designation=low_gears?
That one could even come in under
https://wiki.openstreetmap.org/wiki/Key:hazard#Traffic_hazards
as hazard=low_gear_required?
Thanks
Graeme
