Mandatory signage indicates an instruction that must be carried out. Like the Prohibition Signs, this is a type of regulatory signage which can be linked with a law or standing workplace order and therefore must be carried out without exception.
Mandatory signage is characterised by a white symbol over a blue circle with black text. Alternatively, only black text can be depicted.
