Difficulty: EasyEmergency Vehicles, School Buses, and Work Zones

When driving through a designated work zone, a traffic control flagger signals you to stop, but a temporary traffic signal at the location shows a green light. What is the correct driver action?

  1. Stop as directed by the flagger, because manual directions from authorized traffic control personnel supersede traffic signals.Answer
  2. B
    Proceed through without stopping, because an automated green light always takes priority over human signals.
  3. C
    Slow down slightly and yield, but continue driving without making a full stop.
  4. D
    Increase your speed to pass the flagger quickly and minimize congestion in the work zone.

Answer

Stop as directed by the flagger, because manual directions from authorized traffic control personnel supersede traffic signals.
Manual directions given by authorized traffic control personnel, such as construction flaggers or police officers in work zones, take precedence over electronic traffic signals. Drivers must follow the flagger's explicit instruction to stop regardless of the signal color.

Step-by-Step Solution

1
Identify the conflict between traffic control inputs in the work zone.
A human flagger is signaling to stop, while a temporary traffic signal displays green.
Recognizing competing traffic signals is necessary to apply priority rules.
2
Apply standard traffic law priority rules for work zones.
Authorized personnel (flaggers, police officers) have legal authority over static signs and automated signals.
Flaggers adjust traffic movement dynamically for active hazards and worker safety.
3
Determine the required driver behavior.
Obey the flagger's instruction and bring the vehicle to a complete stop.
Failing to stop when directed by a flagger creates an immediate hazard to road workers and other drivers.
