Difficulty: MediumRegulatory Signs

A motorist is driving in the far-right lane of an arterial street approaching an intersection posted with a white rectangular regulatory sign reading 'RIGHT LANE MUST TURN RIGHT'. If the driver intends to continue traveling straight, which of the following actions must the driver legally take?

  1. Safely signal and change lanes into a lane designated for straight-through traffic prior to reaching the intersection, or complete the right turn if unable to merge safely.Answer
  2. B
    Come to a complete stop at the intersection line, yield to all cross-traffic, and then proceed straight through the intersection from the right lane once clear.
  3. C
    Accelerate and pass traffic on the right paved shoulder to bypass the turn lane and continue straight beyond the intersection.
  4. D
    Proceed straight through the intersection from the right lane unless an active law enforcement officer is physically stationed at the intersection.

Answer

The driver must safely signal and change lanes into a lane designated for straight-through traffic prior to reaching the intersection, or execute the right turn if a lane change cannot be performed safely.
The correct response highlights that white rectangular signs establish mandatory traffic rules. Drivers approaching a lane controlled by a 'RIGHT LANE MUST TURN RIGHT' sign must turn right unless they safely transition into a straight-through lane before reaching the intersection.

Step-by-Step Solution

1
Identify the type and meaning of the posted traffic sign.
The white rectangular sign reading 'RIGHT LANE MUST TURN RIGHT' is a regulatory sign that enforces mandatory directional lane use.
Regulatory signs establish legal requirements that drivers are required by law to obey.
2
Determine the legal driving maneuvers permitted from the right lane.
Vehicles remaining in the right lane are legally required to turn right at the upcoming intersection.
Proceeding straight from a mandatory turn lane creates unexpected traffic conflicts with vehicles turning from adjacent lanes.
3
Select the correct action for a driver intending to travel straight.
The driver must change lanes before entering the intersection area or complete the turn if a safe lane change is impossible.
Once inside the intersection boundary within a mandatory turn lane, the driver must execute the designated turn.
