To turn left from a one-way street to another one-way street, where must a driver begin the turn?

When a driver is making a left turn from one one-way street to another one-way street, it is essential to begin the turn from the left lane. This positioning allows for a safe and efficient turn. By starting in the left lane, the driver aligns their vehicle correctly with the direction they wish to travel on the new street, reducing the risk of interfering with oncoming traffic or vehicles on the right.

Choosing the left lane also helps in making the turn smoother and more predictable for both the driver and other road users. It allows the vehicle to clear the intersection promptly, as left turns typically require more space to navigate than right turns.

The other options would not facilitate a safe or appropriate turn. Starting from the right lane could lead to potential conflicts with oncoming traffic or pedestrians crossing at the intersection. The middle lane may not provide enough room to safely transition into the left-hand lane of the new one-way street. Choosing to begin the turn from any lane could create confusion and increase the likelihood of accidents. Therefore, steering from the left lane is the best practice in this situation.
