When turning left, what must you do?

When turning left, it is essential to yield to vehicles approaching closely from the opposite direction. This ensures that oncoming traffic has the right of way, preventing accidents and collisions. Yielding allows you to assess the speed and distance of oncoming vehicles, helping you make a safe and informed decision about when to make your turn.

Leaving room on the right for other vehicles to pass is not always applicable or necessary during a left turn, as this might interfere with safely completing the turn. Not crossing any solid yellow line is related to lane discipline, which is important, but does not specifically address the rules of yielding during a left turn. Additionally, while blocking vehicles approaching from the rear is a concern, the primary rule during a left turn involves yielding to oncoming traffic to ensure safety for all parties involved.
