Prohibition signs advise of behaviour or actions that are not permitted. The sign background is white, with the annulus and slash displayed in red over a black action symbol. Any necessary text is displayed underneath in black lettering. A common example is a No smoking sign. All prohibition signs are manufactured to comply with Australian Standards.
Substrates: Prohibition signs are offered in Metal, Self Adhesive Vinyl or Polypropylene substrates, depending on the specific design.
