Question

Difficulty: HardWork Zone Safety and Construction Hazards

Approaching a utility repair site on a roadway, a motorist observes a temporary signal light showing green. At the entry of the work area, an authorized traffic control flagger extends a red STOP paddle directly toward approaching traffic. Which action must the driver take under traffic safety rules?

  1. Bring the vehicle to a complete stop as instructed by the traffic flagger, because manual directions from authorized work zone personnel supersede traffic lights.Answer
  2. B
    Continue driving at the posted speed limit because an illuminated green signal light overrides manual hand signals from field workers.
  3. C
    Slow down and yield right-of-way, but maintain momentum without stopping since green signals permit entry into the area.
  4. D
    Treat the conflicting instructions as an advisory warning only and proceed cautiously at your own discretion.

Answer

The driver must bring the vehicle to a complete stop as instructed by the traffic flagger, because manual directions from authorized work zone personnel supersede automated traffic signals.
In any work zone or traffic control setup, directions provided by authorized flaggers or traffic officers take legal precedence over automated signals and standard traffic control devices. Drivers must obey the flagger's STOP paddle immediately.

Step-by-Step Solution

1
Identify the conflict between traffic control devices
The temporary signal shows green, while an authorized human flagger displays a STOP paddle.
Recognizing conflicting signals is essential for identifying which traffic rule applies.
2
Apply the rule of traffic signal priority in work zones
Manual signals from authorized flaggers override electronic signals and posted regulatory signs.
Flaggers respond dynamically to real-time hazards, worker positions, and equipment movements in construction zones.
3
Determine the required driver action
Come to a full stop before the flagger's position and wait for further instructions.
Complying with the flagger ensures the safety of construction workers and opposing traffic.
