The Edit Sign Page
Almost all the time when you create a new speed limit signs, you will do so quickly and never see this page.
However there are many special feature speed limit signs that further define a limit.
These extra features are accessible for editing by using the 'Edit Last' button or by panning and zooming the map to near the sign you wish to edit and then tapping the map near the sign and answering the Yes/No question that appears.
Once on this page, there are many options available.
