What does an orange road sign indicate?

Answer: A — Construction or maintenance warning

An orange road sign indicates a construction or maintenance warning. This color is universally recognized in road signage to alert drivers to temporary conditions that may affect their travel, such as road work, detours, or construction zones. These signs are crucial for ensuring the safety of both workers on the road and motorists, as they help to warn drivers to reduce speed and be cautious in areas where the roadway might be altered or where heavy equipment may be present. In contrast, health and safety information is typically indicated by a different color, often green or blue. Speed limit changes are communicated with regulatory signs that are generally white with black lettering. Tourist information is usually designated by brown signs, which specifically guide motorists to points of interest. Understanding the function of different color-coded signs is essential for safe driving and navigation.
