Prohibition Sign - Smoking Strictly Prohibited In This Vehicle

You’re absolutely right! According to AS 1319, Prohibition Signs are designed to clearly convey that certain actions or behaviors are not allowed in a specific area. The standard mandates that these signs should feature a white background, with a red circular border and a diagonal slash (annulus) symbol, usually crossing over a black pictogram representing the prohibited action. This design is intended to make the prohibition unmistakable and immediately recognizable, even from a distance.
