New York Practice Construction Signs

A flag person in a work zone signals you to stop. What does the manual say about following that signal?

  1. A.
    You must obey only when a police officer is also present
  2. B.
    You must obey only if the posted speed limit is below 25 MPH
  3. C.
    You must always obey the flag person's direction Correct
  4. D.
    You may ignore the signal if the road looks clear
The Why

The answer is "You must always obey the flag person's direction"

The manual states drivers must always obey the flag persons in a work zone, and it lists no exception tied to other signs or personnel. Choice B lifts the 25 MPH figure out of the passage and reads it as a threshold for the flagger's authority; the number sets the lowest posted work-area speed limit and has nothing to do with the duty to obey.

Why the others miss

The traps in the wrong answers

A. You must obey only when a police officer is also present

A police officer's presence is not a condition of the flag person's authority. This answer assumes only sworn law enforcement can compel a driver, so a civilian flag person must need backup.

B. You must obey only if the posted speed limit is below 25 MPH

The 25 MPH figure is the lowest posted work-area speed limit, not a switch that turns on the flag person's authority. This answer ties the flag person's authority to the 25 MPH work-zone number, treating two separate rules as one.

D. You may ignore the signal if the road looks clear

The flag person's view of the site is what governs your movement, not your view of the road. This answer applies the everyday judgment a driver uses on an empty street, ignoring the person who has the fuller view of the work happening on the site.
