Most warning signs are which color?

Warning signs use color to alert you to potential hazards ahead. Most warning signs are yellow because the bright yellow instantly signals caution and prompts you to slow down and be prepared for changes in the road or conditions ahead. In traffic sign color coding, red is for stop or prohibition, blue for services or information, and green for directional guidance. Yellow is specifically standardized for warnings, making it the color you expect for those signs. You’ll often see signs like “Curve Ahead” or “Merge” in yellow with black symbols, and in some places fluorescent yellow-green is used in construction zones for even higher visibility.
