You see cones, drums, and barricades ahead on a Nevada highway. What is their purpose?
-
A.
To mark the boundary of a school zone during class hours
-
B.
To indicate a bike lane closed to motor vehicles
-
C.
To divide opposing lanes on a two-way highway
-
D.
To alert drivers and guide them safely through work areas Correct
The answer is "To alert drivers and guide them safely through work areas"
In Nevada highway work zones, cones, drums, and barricades serve two related purposes: to alert drivers to the presence of the work area and to guide them safely through it. The wrong answers reflect confusion with school-zone markers, bike-lane markings, and yellow lane-dividing lines.
The traps in the wrong answers
A. To mark the boundary of a school zone during class hours
Confuses work-zone traffic control devices with markers used at school-zone boundaries. This answer pictures cones deployed at school entrances to mark the reduced-speed zone that's active while kids are on campus.
B. To indicate a bike lane closed to motor vehicles
Confuses work-zone equipment with pavement markings used for bike lanes. This answer reaches for the flexible delineator posts cities plant to shield protected bike routes from car traffic.
C. To divide opposing lanes on a two-way highway
Confuses work-zone equipment with the yellow lines that separate opposing traffic. This answer mistakes the head-to-head split some construction sites set up temporarily for a permanent striping job.
