What is the minimum width for vertical panels used in work zones?

The minimum width for vertical panels used in work zones is significant for ensuring visibility and safety. A width of 8 to 12 inches strikes a balance between being wide enough to be visible to drivers and narrow enough to be manageable and lightweight for transport and setup. Panels in this range can effectively display necessary warnings and instructions without obstructing the pathways or causing other safety concerns in work zones.

This width range is specified to optimize both safety and practical use within the constraints of a work zone environment, where clear and effective communication with drivers is essential for minimizing accidents and ensuring smooth traffic flow. Wider options, while potentially visible, may not be as practical for the specific needs of temporary work zones, where space and maneuverability are often limited.
