What color warning sign indicates danger ahead?

• A. Blue
• B. Green
• C. Yellow
• D. White

Answer: (C)

The color yellow is used for warning signs because it effectively indicates caution and alerts drivers to potential hazards ahead. These signs are often placed in locations where there might be a change in road conditions, such as sharp turns, pedestrian crossings, or construction zones. The bright nature of yellow catches the attention of drivers, prompting them to reduce speed and remain vigilant for any dangerous situations. This color coding system is standardized to help ensure that all drivers can quickly understand and react to warning signs, enhancing roadway safety. In contrast, blue signs typically provide informational guidance such as road services and directions, while green signs indicate road regulations and directional information. White signage is often used for regulatory messages like speed limits and no parking signs, emphasizing rules rather than warnings of danger.
