Final answer:
To make a U-turn on a divided street with multiple lanes, you should start in the leftmost lane that is meant for left turns or U-turns.
Step-by-step explanation:
When driving on a divided street with multiple lanes in your direction and you need to make a U-turn, the correct place to start is in the lane furthest to the left. This typically means you should be in the leftmost lane that is designated for left turns or specifically for U-turns if such signage is present. Ensuring you are in the correct lane before initiating the U-turn is important for the safety of all road users and is usually mandated by traffic laws.
