Prohibition Sign Icons - Blue and Outline No Entry Symbols #1840451 (License: Personal Use)

The image displays two universally recognized prohibition symbols: the top is a vibrant blue circle with a diagonal slash, while the bottom is a clean black outline version on white background. Both follow ISO 7010 standards for clear visual communication of restrictions, commonly used in safety signage, digital interfaces, and instructional materials. Their minimalist design ensures high legibility across scales and contexts.

Used in safety manuals, website UIs (e.g., disabled actions), regulatory signage, and accessibility guides; matches user intent for finding vector prohibition icons for design or compliance purposes.
