Well, the Highway Code says (Rule 188), "Avoid making U-turns at
mini-roundabouts. Beware of others doing this."
I assume that "avoid" is not quite as strong as "prohibited", especially as
drivers are then warned to "Beware of others doing thís".
Also, I know of at least one bus route near me that terminates at an (actually
fairly large) mini-roundabout, where the busses all do a U-Turn.
(https://www.openstreetmap.org/node/1166864821).
However, I think that the diameter of the centre of a mini-roundabout is
irrelevant and even the outer diameter is unlikely to be of use to any map
user, unless thay are planning to do a U-Turn (which they are supposed to
"avoid" doing.

A mini roundabout often doesn't usually have a diameter. Most are jus normal
junctions which have been made mini-roundabouts to set a priority.
So in terms of large vehicles it is the same problem as any other junctions,
whether they can turn left or right.
In the UK, U turns are prohibited at mini-roundabouts, which I would have
thought would be the main usecase for a diameter.

If the actual issue is that HGV cannot pass some road, why not simply mark it
as
`hgv=no`? Besides being simple, it has the additional advantage that routers
will actually already use it and direct HGVs somewhere where they can actually
pass.
Or if some lenghts of HGVs can pass, but others not, then maxlength=*
or maxlength:hgv=* or some of the other alternatives from
https://wiki.openstreetmap.org/wiki/Key:maxlength ?

I see that I was not precise with my question: I am after a way to tag the
overall diameter of the round surface composed of the mini-roundabout road
surface plus the traversable central part. This is an important measure for
trucks. I happen to live near one of these with an outer diameter of 12 m,
and that attracts regularly articulated lorries like the cheese attracts
flies. This triggered the question.

According to the Wiki (with which I happen to agree), a mini-roundabout is
defined as:
"...a special type of roundabout in which the middle can be traversed
<https://wiki.openstreetmap.org/wiki/Traversable> by vehicles, and is
typically used where there is only limited space available. Road traffic
flows in one direction around a point in the middle and the traffic in the
roundabout has right-of-way. The middle of a mini-roundabout is usually
only a painted circle, but there might also be a low, fully traversable
(mountable) dome or island."
As it is traversable, does it really have a diameter? Or, if there is a
painted circle (are traversable domed area) on the ground, perhaps that has
a diameter, but does it matter to any prospective map user?

We have the tag diameter, but I could not find it applied to
mini-roundabouts. Tagging mailing list
