What color are the signs that alert drivers of construction zones?

The signs that alert drivers of construction zones are orange. This color is specifically chosen due to its high visibility and attention-grabbing qualities, which are essential in construction areas where safety is a priority. The bright orange color serves to warn drivers about temporary conditions and hazards related to construction activities, ensuring that they approach these areas with caution. This helps in reducing the risk of accidents and promotes safer driving near construction sites.

Other colors used for signs serve different purposes; for instance, green signs indicate information about directions or guidance, blue signs usually provide information about services, and yellow signs warn about general road conditions or hazards ahead. However, orange is uniquely designated for construction and maintenance work zones to clearly communicate the potential need for reduced speed and heightened awareness.
