Difficulty: MediumRegulatory Signs

A driver approaches an intersection where a white rectangular regulatory sign indicates "RIGHT TURN MUST TURN RIGHT." A law enforcement officer directing traffic at the intersection hand-signals the driver to proceed straight ahead. Which action must the driver take?

  1. Follow the traffic officer's hand signal and proceed straight through the intersection.Answer
  2. B
    Turn right as indicated by the regulatory sign, because posted signs take priority over manual officer signals.
  3. C
    Stop immediately in the lane and wait until the officer leaves before executing the required right turn.
  4. D
    Pass the officer on the right shoulder to complete the turn without disrupting straight-through traffic.

Answer

The driver must follow the traffic officer's hand signal and proceed straight through the intersection.
Directions given by a law enforcement officer or authorized traffic control official always supersede static traffic signs, signals, and road markings. The driver must obey the officer and proceed straight ahead.

Step-by-Step Solution

1
Identify the conflict between the posted traffic control sign and manual traffic control.
Recognize that a posted regulatory sign ("RIGHT TURN MUST TURN RIGHT") conflicts with a law enforcement officer's manual signal to move straight ahead.
Traffic safety rules define a clear hierarchy of authority when multiple traffic controls are present.
2
Apply the legal priority rule for traffic control.
Determine that manual directions given by a law enforcement officer supersede all static signs, signals, and road markings.
Officers direct traffic based on real-time road conditions, emergencies, or traffic flow requirements.
3
Select the mandatory driver response.
Obey the officer's signal and proceed straight ahead safely.
Drivers are legally obligated to follow lawful instructions from traffic officers over static regulatory devices.
