b.Stand in the open lane facing away from traffic
c.Use a STOP/SLOW paddle and wear high-visibility apparel, positioned where drivers can see and safely stop
d.Direct traffic only after dark to avoid glare
Giải thích
Flaggers should use a standard STOP/SLOW paddle as the primary hand-signaling device and wear high-visibility safety apparel, standing in a visible location that gives approaching drivers time to stop. Option a uses a non-standard signal. Option b puts the flagger in danger and out of sight. Option d increases risk by working in low visibility. Proper devices, apparel, and positioning keep both drivers and the flagger safe.
