What is the order of colors on a traffic light, hung top to bottom?

• A. Green, yellow, red
• B. Yellow, red, green
• C. Red, yellow, green
• D. Red, green, yellow

Answer: (C)

The correct order of colors on a traffic light, when hung top to bottom, is red, yellow, and green. This arrangement is standard in many places, as it helps drivers quickly identify the signal status. Red indicates that vehicles must stop, yellow warns that the signal is about to change to red, and green signals that it is safe for vehicles to proceed.

Understanding the order of the lights is essential for safe driving and compliance with traffic regulations. This standard arrangement is designed for uniformity across different regions, meaning that drivers can reliably interpret traffic signals regardless of where they are. The positioning of the lights emphasizes the importance of stopping when the red light is illuminated, as it is always at the top, making it the most visible.
