No speed limit units?[edit]

I see two problems with the content of this chart:

  1. How can a speed limit have no units?
  2. The Isle of Man seems to be marked with a grey dot, so as a place which has "no speed limit units". This is an error anyway, as the speed limits are specified in miles per hour there. See the 'Speed limits' section on page 46 in their Highway Code

This error may be due to a misinterpretation of the fact that some roads there have no speed limit. -- DeFacto (talk). 09:42, 15 July 2021 (UTC)[reply]

I see that Alex Sims has now fixed the Isle of Man issue without mentioning it here. Thanks Alex. That just leaves the question about how a speed limit can have no units, or is it just that there are no speed limits at all in Antarctica or the Heard and McDonald islands (the only remaining grey places as far as I can see)? -- DeFacto (talk). 12:19, 16 July 2021 (UTC)[reply]

With no discussion appearing here in more than a week, I've changed the caption for grey to "No known speed limits". -- DeFacto (talk). 08:49, 25 July 2021 (UTC)[reply]

Liberia[edit]

according to en:Miles per hour, Liberia uses mph only occasionally. So it should be in green color. — Wassermaus (talk) 09:11, 22 March 2023 (UTC)[reply]
