The double yellow kerb blips - some look faded but will probably be seen as compliant by an adjudicator.
There is no requirement for a no loading sign where blips show no loading at any time. But that they have one is a point.
Traffic signs manual:
As the double kerb mark has only one meaning, authorities may decide that adequate guidance is given without “No loading at any time” upright signs or with fewer such signs. However, this could lead to enforcement difficulties, particularly as marks of this type usually need frequent maintenance.
It's always worth challenging as a BB driver.
