Construction zone signs are typically which color?

• A. Orange sign.
• B. Red sign.
• C. Blue sign.
• D. Yellow sign.

Answer: (A)

Signs in work zones use a color system that quickly communicates the type of information to drivers. Construction zone signs are orange to signal a temporary work area, so drivers know to slow down, follow posted instructions, and anticipate changes like lane shifts or workers on or near the roadway. Orange stands out against most backgrounds and is designed for strong visibility in daylight and at night because of reflective material. In contrast, red indicates stops or prohibitions, blue signals services, and yellow is general caution; these colors serve different purposes, which is why orange is chosen specifically for construction and maintenance warnings.
