To turn left from a one-way street onto a one-way street, start from:

  1. The lane closest to the left curb. ✓
  2. The center lane.
  3. Any lane, as long as it seems safe to do so.

Answer: A. The lane closest to the left curb.

Start from the lane closest to the left curb.

Why this is the answer

The handbook's rule for a left turn from a one-way street onto another one-way street is to begin in the far-left lane. On a one-way street, that far-left lane is the lane next to the left curb. The passage also notes that bicyclists may legally use the left turn lane, so check for them before turning. The bank answer matches this starting position.

Why the other answers are wrong

Remember it

Picture the left curb as your starting gate when both streets run one way.
