Orange cones placed through a work zone are used to:
-
A.
Guide drivers away from road construction Correct
-
B.
Mark a school zone boundary
-
C.
Mark a permanent no-passing zone
-
D.
Show where lane changes are restricted
The answer is "Guide drivers away from road construction"
Orange cones are temporary traffic control devices. Their job is to guide drivers around equipment, workers, and torn-up pavement; orange signs warn what is ahead, and the cones mark the path. Cones do not mark school zones, no-passing zones, or lane-change restrictions; those use different signs and pavement markings entirely.
The traps in the wrong answers
B. Mark a school zone boundary
School zones are marked with yellow pentagonal signs, not cones. Misreading: Confuses orange work-zone cones with the yellow five-sided school zone signs described in the School Zones section.
C. Mark a permanent no-passing zone
No-passing zones use yellow signs and solid yellow center lines. Misreading: Confuses temporary work-zone channelizing cones with permanent no-passing zone signs and yellow center-line markings.
D. Show where lane changes are restricted
Restricted lane changes are shown by double solid white lines. Misreading: Confuses work-zone cones with the double solid white line pavement marking that prohibits lane changes.
