 Not sure if I'm right, but all the max speed values are in km/h and not
 in mph.
 
maxspeed values without unit is in km/h, and should be entered without suffix. 
If the speed is in mph the unit should be added. For more information see

for reference purposes, this changed sometime last summer, so
Dominik used to be right.

  The xx mph format has been there ever since I remember (2009). 
There was a mini edit war with someone trying to deprecate the xx mph 
format and make all editors add interfaces to support a single format. 
I guess that explains the extreme reluctance for map data consumers to 
recognize the mph format.   To me as a layman, I don't see xx mph as 
a difficult parse for map data consumers.

The page was restructured at that point, but explicit tagging of mph
units was already documented back in 2008.

hmmm. when i read that page back when i started mapping (about 2 years ago),
there was no reference to mph at all. i must have hit one of those 
points during

the edit war.

I mapped a road the other day which was exactly like this (different
speeds) and wondered exactly the same thing.  The signs I saw applied to
trucks and buses though, more than just hgv/goods.  As Tobias said, your
suggestion is suitable, Id add the suggestion of maxspeed:bus also.

bus in OSM is defined as a bus performing public transport service
[1]. I recently added tourist_bus as this was required for local
jurisdiction (I found an explicit sign: tourist buses [2]).

There is also another issue with busses: the wiki definition (in [1])
defines busses as vehicles with more than 12 seating positions, which
surely is some national legislation, but in other countries this
number might vary (e.g. in Germany it is 8) so I suggest to adjust
this text to a generic term.

The Geneva Convention on Road Traffic, suggests that cars are 1-8 seats
and 'bus' is more than 8.  In Australia, the legislation says 12, so
possibly other countries mismatch also.

It's probably more than 8 passengers + 1 driver in Germany as well, so a bus 
has at least 10 seats (including driver).

 so I suggest to adjust
 this text to a generic term.

Even better would be to just not define these vehicles internationally at all 
and let each jurisdiction decide on which vehicle tags to use for what. Making 
international definitions only confuse new people when they later see other 
rules for their country and drive them towards tagging wrong things. And it 
has been shown often enough: you can't mold the entire world into one tag set.

I've been using maxspeed:hgv for a while. Also, some signs define what an 
hgv is in terms of axles, so I add hgv:minaxles=3.


I also use:

maxspeed:towing
maxspeed:advisory (for the yellow cautionary speed signs for curves)
maxspeed:children_present (for school zones)
