What do black markings and writing on an orange background indicate?

In the context of traffic signs and markings, the combination of black markings or writing on an orange background is commonly used to indicate construction zones. This color scheme is specifically designed to alert drivers to areas where roadwork is occurring, which may present hazards such as workers, heavy machinery, and altered road conditions. The use of orange is a standard practice that helps ensure that these warnings stand out to drivers, prompting them to slow down and exercise caution in these areas for their safety and the safety of construction workers.

This system of color coding is crucial for maintaining order and safety on roadways during construction projects, which can cause unexpected delays or changes in traffic patterns. Understanding these signs is essential for drivers to navigate effectively and safely through construction zones.
