Question

Difficulty: MediumRegulatory Signs

A driver is approaching an intersection where the traffic light is displaying a solid green circular signal. Directly adjacent to the traffic light, there is a white rectangular regulatory sign showing a black right-turn arrow enclosed in a red circle with a red diagonal slash. Which action is the driver legally required to take if they intended to turn right at this intersection?

  1. Refrain from turning right, proceeding straight or turning left if permitted, because a prohibitive regulatory sign overrides a green light movement.Answer
  2. B
    Proceed with the right turn because a solid green traffic signal supersedes static roadside signs.
  3. C
    Bring the vehicle to a complete stop, yield to all cross traffic, and then complete the right turn.
  4. D
    Pass the vehicle ahead within the intersection to execute the right turn before entering the restricted lane.

Answer

The driver must refrain from turning right and instead proceed straight or make another permitted maneuver. Prohibitory regulatory signs (such as No Right Turn) must be followed even when the traffic signal is green.
Regulatory signs with a red slash across an arrow indicate that the specified movement is strictly prohibited. A green traffic light allows vehicles to enter the intersection, but only to make legal movements. Therefore, the driver must obey the 'No Right Turn' sign and continue straight or execute another valid movement.

Step-by-Step Solution

1
Identify the traffic signal state and the regulatory sign indication.
The signal is a solid green light, and the sign is a 'No Right Turn' regulatory symbol (black turn arrow inside a red slash/circle).
Regulatory signs inform drivers of specific legal prohibitions or requirements.
2
Determine the priority of rules governing the movement.
A solid green signal allows traffic to proceed through the intersection in permissible directions, but it does not authorize movements specifically forbidden by regulatory signs.
Movement prohibition signs restrict specific actions regardless of signal color, unless overridden by a uniformed traffic officer.
3
Select the compliant driving maneuver.
Cancel the intended right turn and proceed straight or execute another legal maneuver.
Executing a prohibited maneuver is a traffic violation.
