Question

Difficulty: HardWork Zone Safety and Construction Hazards

When driving through a highway construction work zone controlled by temporary electronic traffic signals, a driver is legally required to proceed through a green light even if a certified human flagger simultaneously signals the driver to stop.

Answer: Answer

Answer

The statement is False. Directions given by human flaggers or traffic control personnel always supersede electronic signals and posted traffic signs in work zones.
The statement is False because direct commands from authorized human flaggers, construction traffic directors, or police officers take legal precedence over all electronic signals, temporary regulatory signs, and standard road rules in active work zones.

Step-by-Step Solution

1
Identify the conflicting traffic control inputs in the scenario.
The scenario features an automated temporary green signal indicating permission to proceed versus a human flagger actively signaling to stop.
Determining proper driver action requires applying the statutory hierarchy of traffic control authority.
2
Apply the legal precedence rule for traffic control devices and personnel in work zones.
Authorized human controllers (flaggers, police officers) occupy the highest tier of authority, overriding electronic signals, signs, and road markings.
Human flaggers actively respond to real-time site hazards, moving equipment, emergency vehicles, or sudden lane obstructions that automated signals cannot detect.
3
Conclude the statement's truth value.
Because the driver must obey the flagger's stop signal despite the green light, the assertion that the driver must obey the light over the flagger is false.
Proceeding through a green light against a flagger's command creates an immediate hazard to construction personnel and constitutes a traffic violation.
