Prohibition signs are used to clearly indicate actions or activities that are not permitted in a specific area. They provide an instant visual message using a red circle and diagonal slash over a recognised symbol, making restrictions easy to understand at a glance.

Commonly used to display messages such as No Entry, No Smoking, No Parking, No Mobile Phones, and similar restrictions, prohibition signs help control access, enforce site rules, and improve overall safety in workplaces and public areas.

Our prohibition signs are available in standard designs or with customisable text and symbols to suit your specific requirements. Suitable for indoor and outdoor use, they’re ideal for workplaces, construction sites, facilities, and public environments where clear instructions are essential.
