What does an orange traffic sign indicate?

Answer: A — Road construction or maintenance warning

An orange traffic sign indicates a road construction or maintenance warning. This color is specifically used to alert drivers to temporary conditions that could affect the flow of traffic, such as construction zones, roadwork, lane closures, or other changes in road conditions. These signs are crucial for maintaining safety, as they inform drivers to be cautious and prepared for potential delays, detours, or alterations in their routes. In various contexts, the use of orange helps to draw attention to the presence of workers, machinery, and other hazards in or along the roadway that may not typically be present under normal circumstances. Thus, recognizing an orange sign is essential for safe navigation through areas where construction or maintenance is taking place.
