1. What is the primary responsibility of a traffic flagger in a temporary
traffic-control zone?
A. Direct construction workers around the work area
B. Control road-user movement safely through or around the work zone
C. Inspect all construction equipment before each shift
D. Determine the project budget
Correct Answer: B. Control road-user movement safely through or
around the work zone
Rationale: A flagger’s primary duty is to protect workers and road users
by controlling traffic movement through or around a temporary traffic-
control area. Effective flagging requires clear communication, proper
positioning, appropriate signaling, and constant attention to changing
traffic conditions.
2. Which characteristic is most important for a person performing
flagging duties?
A. Ability to work without communicating with others
B. Willingness to stand close to moving vehicles
,C. Alertness and sound judgment
D. Ability to operate heavy equipment
Correct Answer: C. Alertness and sound judgment
Rationale: Flaggers must continuously observe traffic, workers, roadway
conditions, and changing hazards. Alertness and sound judgment allow
the flagger to recognize developing risks and respond appropriately
before a conflict occurs.
3. Why should a flagger remain visible to approaching road users?
A. To make the work zone appear more active
B. To ensure drivers can recognize and respond to traffic-control
instructions
C. To allow workers to identify the flagger
D. To reduce the amount of required signage
Correct Answer: B. To ensure drivers can recognize and respond to
traffic-control instructions
Rationale: Drivers must have sufficient opportunity to see, understand,
and obey the flagger’s instructions. Visibility is therefore essential to
effective traffic control and helps reduce the possibility of sudden
braking, lane conflicts, or collisions.
4. Where should a flagger generally stand when controlling
approaching traffic?
A. Directly in the travel lane
B. Behind a parked vehicle
,C. In a safe position where approaching drivers can see the flagger
clearly
D. Immediately beside the rear bumper of a work vehicle
Correct Answer: C. In a safe position where approaching drivers can
see the flagger clearly
Rationale: The flagger should occupy a position that provides adequate
visibility to approaching traffic while maintaining a safe escape path.
Standing directly in the travel path or beside moving equipment
unnecessarily exposes the flagger to hazards.
5. What should a flagger do if a driver appears not to understand a
traffic-control instruction?
A. Step into the vehicle's path to force compliance
B. Maintain a clear, recognizable signal and seek assistance according to
the traffic-control plan
C. Turn away from the driver
D. Allow the driver to proceed without further consideration
Correct Answer: B. Maintain a clear, recognizable signal and seek
assistance according to the traffic-control plan
Rationale: Confused or noncompliant drivers create a significant hazard.
The flagger should remain visible, use standardized signals, avoid
placing themselves in danger, and follow established procedures for
handling difficult traffic situations.
6. What is the main purpose of high-visibility clothing for flaggers?
, A. To protect clothing from dust
B. To identify the contractor
C. To make the flagger conspicuous to approaching road users and
equipment operators
D. To provide protection from rain
Correct Answer: C. To make the flagger conspicuous to approaching
road users and equipment operators
Rationale: High-visibility apparel helps drivers and equipment operators
detect the flagger against the roadway and work-zone background.
Increased conspicuity is particularly important during low-light
conditions, congestion, and complex work activities.
7. Why should a flagger avoid unnecessary conversation while actively
controlling traffic?
A. Conversation makes the shift longer
B. It can distract the flagger from traffic and changing hazards
C. Drivers are prohibited from hearing conversations
D. It eliminates the need for hand signals
Correct Answer: B. It can distract the flagger from traffic and changing
hazards
Rationale: Flagging requires continuous attention. Unnecessary
conversation, mobile-phone use, joking, or other distractions can cause
a flagger to miss an approaching vehicle, changing roadway condition,
or worker movement.
