As a white road marking, it is so widely authorised for particular locations or authorities in England that there is a DfT drawing of it: NP545RM. You can see it in this area-wide authorisation for Milton Keynes for example: link.

It has also been authorised for individual places in Scotland, which implies that there’s no Scotland-wide authorisation. The official list (without drawings unfortunately) is here.

Many authorities put down a coloured road marking, presumably without authorisation, but it usually looks dreadful after a couple of years.
