Difficulty: MediumTraffic Officer Signals and Temporary Control Devices

When approaching a roadway construction zone, a motorist observes an electronic arrow board signaling drivers to merge into the left lane, but an authorized flagger positioned at the zone boundary actively displays a STOP paddle to oncoming traffic. The motorist is legally required to follow the flagger's instruction to stop rather than following the direction of the electronic arrow board.

Answer: Answer

Answer

The statement is TRUE. Motorists must obey manual directions given by authorized traffic control personnel, which supersede automated electronic signs or arrow boards in work zones.
Directions given by authorized traffic control personnel, such as police officers and construction flaggers, take legal priority over all electronic signals, arrow boards, and posted signs. Therefore, drivers must stop as instructed by the flagger regardless of what the arrow board displays.

Step-by-Step Solution

1
Identify the two conflicting traffic control indicators in the scenario.
An automated electronic arrow board indicates a lane merge, while an authorized human flagger actively orders traffic to stop.
Resolving the scenario requires determining which indicator takes legal precedence under work zone traffic rules.
2
Apply the rule governing authority hierarchy between traffic personnel and automated devices.
Direct commands from authorized personnel override all static or automated traffic control devices.
Human flaggers manage real-time road conditions and immediate hazards that automated equipment cannot evaluate.
