Which statement best describes the function of channelizing devices in a work zone?

• A. They are permanent barriers
• B. They are portable lights used at night
• C. They are used to warn drivers of detours only
• D. They are movable barriers and cones used to guide traffic through a work zone and protect workers

Answer: (D)

Channelizing devices are the movable barriers and cones that shape the traffic pattern through a work zone. Their function is to guide vehicles along a safe path and create a protective buffer around workers, helping to separate moving traffic from the work area. Because they can be repositioned as work progresses, they are not permanent barriers. They’re more than just warning lights or detour indicators; their primary purpose is to channelize traffic and protect workers by clearly delineating the work zone boundaries.
