Which combination best describes safety signs used internationally?

• A. Text only
• B. Color scheme
• C. Both text and graphic symbols
• D. Neither text nor symbols

Answer: (C)

International safety signs are built to be understood by people from many languages, so they rely on standardized graphic symbols (pictograms) that communicate the hazard or instruction at a glance, with color coding that reinforces the message (for example, red signals prohibition or danger, yellow signals caution, green signals safety or exits). In practice, signs often pair these universal symbols with concise text to provide clear, local context. Text alone wouldn’t bridge language gaps, and color or symbols alone may not convey the exact action required. So using both text and graphic symbols offers the most reliable, universal communication.
