It has nothing to do with urban, the same<br> rule will apply on lit rural roads.

It is always<br> signed as you enter the zone. Whilst it's useful for confirmation whilst<br> driving, it is not really useful for mapping, you need to survey the<br> start points so that it can be split at the appropriate points.<br> <br> Phil (trigpoint)<br> <br> <br> On 30 April 2018 18:41:26 BST, Tobias Zwick <osm@westnordost.de> wrote:<br> <br> Hi there<br> <br> On tagging implicit speed limits in the United Kingdom, the wiki lists<br> the following values [1] for "maxspeed:type":<br> <br> GB:nsl_single (=60 mph), GB:nsl_dual (=70 mph) and GB:motorway (=70 mph)<br> <br> I understand that the current legislation defines a road with<br> road-lighting as a built-up area in which a lower implicit speed limit<br> of 30 mph applies.
