Question

Difficulty: MediumTraffic Officer Signals and Temporary Control Devices

When a uniformed traffic officer explicitly directs a driver to proceed through an intersection, the driver must obey the officer's directions even if a temporary portable stop sign posted at the intersection indicates that vehicles must stop.

Answer: Answer

Answer

The statement is true. Directions from a uniformed traffic officer legally override all posted signs, signals, and temporary control devices.
Under vehicle codes worldwide, the directions of an authorized traffic control officer supersede all automated traffic signals, permanent signs, and temporary control devices.

Step-by-Step Solution

1
Identify the legal hierarchy of traffic control authority.
Authorized personnel (police officers, traffic control personnel, flaggers) occupy the highest level of authority on public roadways.
Human controllers actively assess and manage live incidents, construction hazards, and emergency situations in real time.
2
Determine how contradictory instructions between an officer and a temporary sign are resolved.
The driver must follow the officer's hand signal to proceed rather than stopping for the temporary sign.
Traffic laws explicitly require motorists to obey officer directives regardless of contradictory signs or signal lights.
