South Carolina Driver's Permit Practice Exam

All work zone symbols or signs have what color background and letter combination?

1. Yellow background and black letters

2. Orange background and black letters

3. Red background and white letters

4. Green background and yellow letters

The correct answer is: Orange background and black letters

Work zone symbols and signs are designed to alert drivers to construction or maintenance activities that may result in altered traffic patterns, reduced speeds, or potential hazards. The correct answer is based on established standards for traffic control devices. An orange background with black letters is specifically utilized for work zone signs because the color orange is universally recognized as a warning color in traffic signs. It signifies caution and indicates that drivers should be prepared for changes in road conditions or unexpected obstacles. The combination of orange and black ensures high visibility and readability, allowing drivers to quickly assess the situation ahead and make safe decisions. Using any other combination, such as yellow and black or red and white, is reserved for different types of signs. Yellow signs are typically used for general warning signs, while red is usually associated with stop or prohibition signs. Green is used for informational signs, indicating permitted movements or directions. Therefore, the orange and black combination is specifically tailored for work zones to ensure it stands out and communicates urgency effectively.
