Difficulty: HardRegulatory Signs

A driver is traveling in a designated lane controlled by a vertical rectangular white regulatory sign displaying black lettering that reads 'RIGHT LANE MUST TURN RIGHT'. Upon approaching the intersection, the driver realizes they intended to continue straight. The lane boundary is marked with a solid white pavement line, and traffic is present in the adjacent lane. Which action is legally required of the driver?

  1. Complete the mandatory right turn at the intersection, then use an alternate route or safe turning maneuver to return to the intended path.Answer
  2. B
    Bring the vehicle to a full stop at the intersection line, display a left turn signal, and proceed straight once all cross traffic yields.
  3. C
    Reduce speed significantly below the flow of traffic to wait for a gap, then cross the solid white lane boundary to merge into the straight-through lane.
  4. D
    Accelerate past the adjacent vehicle and cut ahead into the intersection to overtake straight-moving traffic before completing the intersection traversal.

Answer

The driver must complete the right turn as directed by the regulatory sign and re-route safely after executing the turn.
Black-and-white rectangular regulatory signs convey mandatory traffic laws. A sign indicating 'RIGHT LANE MUST TURN RIGHT' obligates every driver in that lane to make a right turn. The safest and legally required procedure when trapped in a mandatory turn lane is to complete the turn as instructed and re-route downstream.

Step-by-Step Solution

1
Identify the sign type and legal authority
The white rectangular sign reading 'RIGHT LANE MUST TURN RIGHT' is a regulatory sign that establishes a mandatory movement direction.
Regulatory signs communicate mandatory traffic laws that drivers must obey under all standard conditions.
2
Evaluate lane markings and current vehicle position
The vehicle is in the dedicated right-turn lane separated by a solid white line near the intersection.
Solid white lines indicate lane boundary restrictions where changing lanes is discouraged or prohibited, reinforcing the regulatory sign.
3
Determine the mandatory driver action
The driver must execute the right turn at the intersection and adjust their route afterwards.
Attempting to travel straight, stop unexpectedly, or cut across lanes violates regulatory commands and endangers surrounding traffic.
