Step-by-step explanation:
When turning left from a two-way street onto a one-way street, you should swing wide to the left before turning. This allows you to position your vehicle correctly and safely complete the turn. By swinging wide, you create space for your vehicle and ensure that you don't cut the corner too sharply, potentially causing a collision or hitting a pedestrian or bicyclist.
