Drivers are required to obey instructions from
- Security guards patrolling parking lots
- Other drivers whose vehicles are broken down on the roadway
- Flaggers (signal persons) at construction sites ✓
Answer: C. Flaggers (signal persons) at construction sites
Drivers must obey special signs or instructions given by workers such as flaggers in work zones.
Why this is the answer
The handbook's work zone section tells you to go through construction areas carefully and to obey special signs or instructions from workers such as flaggers. A flagger is the person directing traffic past cones, drums, and slow-moving equipment, so their signals carry the same weight as other work zone directions. The handbook lists flagger instructions as part of the rules you follow in a work zone, which is why their directions are the ones you are required to obey.
Why the other answers are wrong
- A. Security guards patrolling parking lots — Nothing in the handbook gives security guards patrolling parking lots any authority to direct traffic on the road.
- B. Other drivers whose vehicles are broken down on the roadway — A driver stopped with a broken-down vehicle is not directing traffic, and the handbook does not say to follow their instructions.
Remember it
In a work zone, treat the flagger like a traffic signal: slow down, give space, and do what they signal.
