When turning left on roads divided by a center line, utilizing the leftmost lane is the correct practice because it aligns with standard driving procedures that prioritize safety and efficiency. The leftmost lane is intended for left turns, as it positions the vehicle correctly for the maneuver without the risk of crossing over lanes of traffic that are moving straight ahead.

This method minimizes potential conflicts with vehicles that are traveling in the opposite direction, thereby reducing the chances of accidents. When drivers use the leftmost lane to execute a left turn, it also helps maintain the flow of traffic for others who may be turning or proceeding straight.

The approach of switching lanes just before the turn can lead to confusion and increased risk, as it may not provide sufficient time for other drivers to anticipate the change. Additionally, turning from the rightmost lane is not advisable since this position does not provide an appropriate angle for left turns and could inadvertently cause obstruction to vehicles moving in the other direction. Lastly, turning from any available lane disregards the structured flow of traffic and increases the likelihood of collisions, especially in busy areas.
