Which group of items does the Florida manual classify as channeling devices in a work zone?
-
A.
Yellow diamond warning signs and roadside mile markers.
-
B.
Barricades, vertical panels, drums, and cones. Correct
-
C.
Traffic lights, drawbridge gates, and railroad crossbucks.
-
D.
Painted stop lines and diagonal pavement markings.
The answer is "Barricades, vertical panels, drums, and cones."
The manual lists channeling devices as barricades, vertical panels, drums, and cones. A learner reading channeling as any lane-guiding surface reaches for D's painted stop lines and diagonal markings, missing that the manual defines channeling as physical objects placed around active work rather than pavement art.
The traps in the wrong answers
A. Yellow diamond warning signs and roadside mile markers.
Warning signs and mile markers are guide and warning devices, not channeling devices. This answer confuses permanent roadside signage with the temporary physical devices placed around active work.
C. Traffic lights, drawbridge gates, and railroad crossbucks.
These belong to earlier sections on traffic control, not to work-zone channeling. This answer recycles equipment from other traffic-control sections instead of the channeling-device list.
D. Painted stop lines and diagonal pavement markings.
Pavement markings are markings, not the physical channeling devices the manual lists. This answer reads channeling as any lane-guiding surface, missing that the manual defines it as physical objects.
