Step-by-step explanation:
The background color of a warning sign in a construction zone is typically orange. This color is chosen for its high visibility and ability to alert drivers and pedestrians of potential hazards. In construction zones, warning signs play a crucial role in ensuring safety by signaling changes in the road conditions, detours, or the presence of workers and machinery.
The color orange is often associated with safety and caution due to its high visibility in various light conditions. It's not just in construction; orange is also used in other safety gear and signs, ranging from traffic cones to the vests worn by emergency workers. The selection of orange as a signal of caution is a testament to the importance of visibility and attention in areas where being alert can prevent accidents and injuries.
