To what length should the staff for the red flag be fastened?

The correct length for the staff for the red flag to be fastened at 36 inches aligns with established guidelines for visibility and effectiveness in traffic control. A 36-inch flag staff is optimal because it ensures that the flag is positioned at a height that makes it easily visible to motorists, even from a distance or when approached from various angles. This height is especially important in construction or maintenance areas where clear signage and flags are crucial for maintaining the safety of both workers and drivers by effectively conveying information about potential hazards or changes in traffic patterns.

The specified length of 36 inches strikes a balance between being tall enough to gain attention and remaining manageable for those handling the flag, thus enhancing its practical application in temporary traffic control scenarios. Ensuring that the flag staff meets this standard is essential for compliance with traffic control device regulations and helps promote safety in work zones.
