Question

Difficulty: MediumRegulatory Signs

A driver approaches an intersection where the lane is posted with a white rectangular regulatory sign stating 'RIGHT LANE MUST TURN RIGHT'. However, a uniformed law enforcement officer stationed at the intersection explicitly signals the driver to proceed straight through from that lane. What is the driver legally required to do in this situation?

  1. Follow the directions given by the law enforcement officer and proceed straight through the intersection.Answer
  2. B
    Make the right turn as indicated by the regulatory sign, because posted traffic signs take precedence over officer hand signals.
  3. C
    Attempt to merge into the adjacent straight-through lane immediately within the intersection to comply with the sign.
  4. D
    Stop complete in the lane and treat the sign as a mandatory yield until all traffic clears, ignoring the officer.

Answer

Follow the directions given by the law enforcement officer and proceed straight through the intersection.
Directions given by a law enforcement officer or traffic control personnel always take precedence over posted regulatory traffic signs, signals, and pavement markings. When an officer instructs a driver to proceed straight from a lane designated for right turns only, the driver must obey the officer.

Step-by-Step Solution

1
Identify the conflict between the posted regulatory sign ('RIGHT LANE MUST TURN RIGHT') and the direct manual signal of the traffic officer.
Recognize that two conflicting commands exist at the intersection.
The driver must establish which traffic control instruction takes priority under traffic law.
2
Apply the statutory order of priority for traffic control commands.
Law enforcement officer directions supersede all signs, signals, and pavement markings.
Traffic officers manage dynamic road conditions and emergency scenarios that static signs cannot account for.
3
Select the action corresponding to the officer's explicit hand signal.
Proceed safely straight through the intersection from the right lane as directed.
Complying with the officer maintains intersection safety and legal compliance.
