Giải thích
The California MUTCD requires flaggers to wear high-visibility retroreflective apparel, use an approved STOP/SLOW paddle (or lights at night), and stand where they are clearly visible with a planned escape route away from traffic. Option a reflects this. Hand-only signals (b), standing in the live lane with your back to traffic (c), and dark clothing (d) all sharply increase the risk of being struck.
