SafetyCâu 698 / 700
A flagger controls traffic in a work zone. Which combination BEST matches California MUTCD flagging requirements?
a.Hand signals only, with any bright shirt
b.A STOP/SLOW paddle as the primary hand-signaling device, plus high-visibility apparel and flagger training
c.A red flag only, at night, with no reflective clothing
d.A whistle and dark clothing so drivers focus on the whistle
Giải thích
Correct: the STOP/SLOW paddle is the primary hand-signaling device, and flaggers must wear high-visibility retroreflective apparel and be trained in proper flagging procedures. Bare hand signals or a plain bright shirt are not sufficient. A flag alone is a backup method with limits, especially at night without reflective clothing. Dark clothing with only a whistle leaves the flagger unseen and is unsafe.
