I had a bit of an interest in tagging speed limits a few years back. It's
way more complicated than it should be in the UK. Researching led me down a
bit of a rabbit hole of legislation & case law.
I made the following personal notes about UK limits and how to recognise
them, which I think is
So then, in case the user answers in the app that there is no sign, the
app could ask the user whether the street is lit. Only if it is not lit,
it tags the street as nsl_single/nsl_dual. Would that solution be correct?

If it is marked as a 20mph Zone, the limit must be self-enforcing
through chicanes, speed bumps and similar. Repeaters are neither needed
nor permitted. If it is not a Zone, but simply a road with a 20mph
limit, repeaters are required.

They have the word Zone on the sign

Does the "there are no repeater signs" rule only apply for the default
30 mph limit (and the 20 mph zones)? Or in other words, if there is an
explicit different limit posted, let's say 40 mph, does it have to be
repeated at each intersection and feed roads?

Am I missing something? The 20 mph signs are the same as all speed restrictions
signs are they not?

EDIT: sorry, silly question. For some reason I overlooked that JOSM works with

I realise I'm going a bit OT here and this is more a dev topic, but while
we're on this topic, I'm just wondering whether it possible to authenticate via
OSM OAuth from an app directly? StreetComplete calls the login page of OSM by
invoking the web browser.
I'm guessing the answer might be
That should include Leicester.

At that point the easiest option is for the app to simply stop. Add no
data to OSM.
And yes, you may have to go back several roads before you see the
speed limit sign. No all local authorities put up the repeater signs
but that doesn't mean that the speed

In fairness to Tobias:

This tag is not invented, it exists in other countries where slow zones
exist as well.
Also, there *is* something special about it, otherwise the sign would
not be different from a normal maxspeed sign, wouldn't it? (And the
wikipedia article wouldn't exist)
The special thing about it, is that the
Okay, I have the impression that the tenor of the answers I got so far
is that a "maxspeed:type=GB:something" tagging would not be necessary
because in practice in the UK, any 30mph limit on lit streets will be
posted explicitly. Thus, the maxspeed should be specified explicitly

No, 20mph zones and roads with 20mph limits are different legal concepts and
are signed differently. A 20mph zone must have physical
I wouldn't invent a type tag, it's maxspeed = 20 mph because that's what the
