Which color combination is used for Do Not Enter signs and Wrong Way signs?

• A. Black and White
• B. Blue and White
• C. Green and White
• D. Red and White

Answer: (D)

Red and white indicate prohibition and wrong direction, which fits Do Not Enter and Wrong Way signs. Red signals stopping or forbidding action, grabbing attention quickly, while white provides high contrast for the letters and symbols, making them easy to read at a glance. These signs are standardized so drivers instantly recognize the restriction and act accordingly—Do Not Enter to prevent entering a restricted roadway, and Wrong Way to avoid traveling in the wrong direction. Other color combinations are used for different types of signs (informational or guidance), so they don’t convey the same urgent prohibition.
