Which of the following is not typically considered a key element of flagger apparel?

• A. High-visibility color
• B. Reflective material
• C. Safety glasses
• D. Both high-visibility color and reflective material

Answer: (C)

The main idea here is signaling and visibility. Flagger apparel is designed so drivers can spot the worker quickly, which is achieved through high-visibility color and reflective material that stand out in daylight and at night. Safety glasses, while important for eye protection in a construction zone, don’t contribute to making the flagger more visible or signaling their presence to motorists. That’s why safety glasses are not typically considered a key element of flagger apparel. The other features—bright, high-visibility color and retroreflective material—are essential for conspicuity in traffic control.
