Question

Difficulty: MediumTraffic Light Signals

A driver enters a signalized intersection on a steady circular green light planning to turn left, but must yield to oncoming traffic and stop inside the intersection. While waiting for a safe gap, the traffic signal light transitions to steady yellow and then steady red. Which action is the driver legally required to take to clear the intersection?

  1. Complete the left turn safely as soon as oncoming traffic stops or clears, even though the light has turned red.Answer
  2. B
    Shift into reverse and back up behind the crosswalk line before cross-traffic receives a green signal.
  3. C
    Remain stationary in the center of the intersection until the signal light cycles back to green for their direction.
  4. D
    Accelerate abruptly across oncoming lanes as soon as the signal turns yellow to force oncoming traffic to yield.

Answer

Complete the left turn safely as soon as oncoming traffic stops or clears, even though the light has turned red.
When a driver enters an intersection legally on a steady green light to execute an unprotected left turn, they retain the right to complete the turn safely after oncoming traffic yields or stops, even if the traffic light turns red during the wait. This action prevents gridlock and clears the intersection for cross-traffic.

Step-by-Step Solution

1
Determine the legality of the initial entry into the intersection.
The vehicle legally entered the intersection under a circular green signal.
Drivers making an unprotected left turn may enter the intersection on green while waiting for oncoming traffic to clear.
2
Determine the required legal action when the light changes to red while trapped in the intersection.
The driver must clear the intersection by completing the turn when safe.
Traffic laws dictate that vehicles legally positioned inside an intersection when the signal changes must clear it immediately to prevent gridlock.
