Is it possible to get the current speed limit of a road? I’m not sure if this would be done using the ‘Maps' app as I don’t think its holds speed limit data.
Is anyone able to point me in the right direction?
There is no functionality in MapKit for retrieving speed limits.
You may be able to get it by querying Google directly, or by querying some other third-party speed-limit database. However, it's probably unlikely that you'd find a service offering that kind of data for free.
Figure out where from where you going to get the data and then someone can likely help with how you'd retrieve it.
