What color sign is used to indicate construction or repair areas?

The color orange is specifically designated for construction and repair area signs. This color is used to alert drivers to potential hazards and changes in road conditions due to construction activities. Orange signs serve as a cautionary signal that there may be workers present, machinery, or other obstructions, encouraging drivers to approach the area with increased awareness and reduced speed.

In contrast, yellow signs typically indicate general caution and are used for warning signs regarding road conditions or hazards that do not specifically relate to construction. Blue signs are usually reserved for informational purposes, such as services available along the road, and green signs provide directional information or guide signs. Therefore, orange is the distinctive color that stands out during such activities, ensuring that drivers are adequately informed of the changes in their driving environment related to construction and repair.
