Construction zones are typically marked with what shape of signage?

Construction zones are typically marked with diamond-shaped signage because this shape is universally recognized as indicating a warning or caution to drivers. The diamond shape is designed to draw attention and alert motorists to potential hazards ahead, such as road work, changes in traffic patterns, or detours. This recognizable shape helps ensure that drivers are aware of the need to slow down and proceed with caution, thereby reducing the likelihood of accidents in areas where temporary changes to road conditions may pose risks. The use of brightly colored backgrounds, often in shades of orange or yellow, further enhances visibility and awareness, reinforcing the importance of vigilance while driving through construction zones.
