How are traffic signs categorized, and what colors or shapes indicate each category?

• A. Regulatory signs (commands, red/white); warning signs (yellow/orange, diamond shapes); guide/information signs (green/blue, informational shapes)
• B. Regulatory signs (green/blue); warning signs (red), guide signs (yellow)
• C. All signs use the same color palette regardless of category
• D. There is no standard meaning for sign shapes and colors

Answer: (A)

Traffic signs are organized by what they tell you to do, warn you about, or guide you to. Regulatory signs convey commands or prohibitions and are designed to stand out with red and white colors; you’ll often see rectangular shapes, with the iconic stop sign as a red octagon as a special case. Warning signs alert you to hazards ahead and use a bright yellow or orange background with a diamond shape to catch your attention. Guide or information signs help you navigate or find services, and they typically use green or blue backgrounds with white lettering and are usually rectangular. This mapping matches the described idea: regulatory signs in red/white, warning signs in yellow/orange and diamond-shaped, and guide signs in green or blue with informational shapes. Construction signs also use orange and are commonly diamond-shaped, reinforcing the same color-shape cue system.
