What color are the letters on Stop/Slow retroreflective paddles typically?

• A. White
• B. Red
• C. Yellow
• D. Green

Answer: (B)

The letters on Stop/Slow retroreflective paddles are typically red because red is universally recognized as the color that indicates a stop signal. This is crucial for ensuring maximum visibility and comprehension from drivers approaching a work zone or area where traffic needs to be controlled. The color red captures attention effectively, which is critical for the safety of both flaggers and motorists. In contrast, white, yellow, and green are not used for the text on these paddles, as they can convey different messages or warnings that do not align with the specific function of stopping traffic. White is generally associated with regulatory signs, yellow is used for cautionary messages, and green often indicates go or safety—none of which is suitable for a stop signal. Thus, the red lettering is integral to the flagger's role in directing traffic safely.
