where should you begin a left turn from a one-way street onto a one-way street?

You should begin your left turn from the lane closest to the left curb (the far-left lane) on the one-way street.

Quick Scoop

• On a one-way street turning left onto another one-way street, move into the far-left lane before the intersection.
• Start your turn from that far-left lane, as near as practical to the left curb or edge of the roadway.
• Turn into the left lane of the new one-way street, unless signs, markings, or safety conditions require a different lane.
• Always obey any lane-use arrows, “left turn only” markings, or posted signs at the intersection.

A simple way to picture it: imagine you are riding the “left wall” of a hallway; you start your turn from that left wall, and you enter the next hallway staying along its left side, unless road markings clearly tell you otherwise.
