Final answer:
When turning left onto a multi-lane road, the driver should change to the lane closest to the center line once stabilized.
Step-by-step explanation:
When turning left onto a multi-lane road, the driver should change to the lane closest to the center line once stabilized. This is known as the left or inside lane. By positioning themselves in this lane, the driver maximizes their visibility and allows for other vehicles to pass on the right. Additionally, staying in the left lane can make it easier to make subsequent turns or change lanes if needed.
