MUTCD Section 2B.58 describes rolling fence sections requiring what appearance?

• A. Horizontal strip of retroreflectorized sheeting on both sides with vertical red and white stripes at 16-inch intervals.
• B. No reflectors.
• C. Bright orange stripes.
• D. Only at the top.

Answer: (A)

Rolling fence sections are meant to be highly visible from all directions in a work zone. The standard requires a horizontal strip of retroreflective material on both sides of the fence, paired with vertical red and white stripes placed at 16-inch intervals. This combination ensures the barrier is easily seen at night when illuminated by headlights and quickly recognizable during the day due to the distinctive stripe pattern. The red and white vertical stripes act as a clear, standardized warning cue, while the retroreflective strip enhances nighttime conspicuity. Other approaches—such as no reflectors, simply bright orange stripes, or marking only the top—do not provide the same level of consistent visibility and recognizability required for temporary barrier devices in traffic environments.
