What is the height requirement for PCMS boards in urban areas?

The height requirement for Portable Changeable Message Sign (PCMS) boards in urban areas is established to ensure visibility and effectiveness in communication with drivers. Setting the height at 7 feet allows for optimal viewing of the signs over traffic and other obstacles that may be present in an urban environment. This height helps ensure that messages are easily readable from a distance, reducing potential confusion or distraction for drivers navigating through busy areas.

Meeting this height requirement is crucial for work zone safety, as it helps ensure that motorists receive timely information about upcoming road conditions or changes, which can significantly improve safety outcomes in construction and maintenance zones. In contrast, other height options may not provide the same level of visibility, which can compromise communication and lead to dangerous situations on the road.
