What is the minimum size for construction warning signs?

The minimum size for construction warning signs is 48" x 48". This size is specified to ensure that the signs are highly visible and can be easily noticed by drivers and pedestrians, especially in environments where there may be a lot of distractions or competing visual cues. Larger signs enhance readability from a distance, providing critical information about potential hazards, detours, or regulatory instructions. Proper sign visibility is essential for the safety of both workers and the public, as it helps in reducing accidents and ensuring that everyone is aware of construction activities taking place in the area.
