Work zone barriers, drums, cones, and signs are used to:
- Make drivers angry about slow traffic.
- Inconvenience drivers.
- Keep traffic out of hazardous work zones. ✓
Answer: C. Keep traffic out of hazardous work zones.
Barriers, drums, cones, and signs are placed to keep traffic out of hazardous work zones.
Why this is the answer
The handbook describes work zones as places with workers, slow-moving equipment, and closed lanes, and it tells you to go through them carefully by slowing down, leaving extra space, and expecting sudden stops. It says cones, drums, or other barriers guide you through the work zone, and that you should merge as soon as it is safe without crossing them. So the markers exist to keep your vehicle separated from the work and out of the areas where crews and equipment are operating.
Why the other answers are wrong
- A. Make drivers angry about slow traffic. — Nothing in the handbook treats work zone markers as a way to provoke drivers; they are there to control where traffic goes around the work.
- B. Inconvenience drivers. — The markers are not placed to inconvenience anyone but to guide traffic safely past workers, equipment, and closed lanes.
Remember it
Treat cones and drums like a fence: stay on your side of them and merge before you reach them, never across them.
