Red 18 Plus Prohibited Warning Sign

An unmistakable warning symbol is shown, indicating content or access restricted to individuals aged 18 and older. It prominently features the number 18 in dark grey, set against a clean white background within a circular shape. A striking red circle outlines the symbol, with a distinct red diagonal line cutting across the numbers, signifying prohibition or exclusion for those under the specified age. This universally understood icon is commonly used for age-gated materials or environments.
