What should you do to make a left turn when the traffic light is green?

Answer: D — Yield to oncoming traffic and turn when safe to do so.

When making a left turn at a green light, it is crucial to yield to oncoming traffic before completing the turn. This means that although you have a green light, there may be vehicles coming toward you that could pose a danger if you proceed without ensuring it's safe. Yielding allows you to assess the path ahead and only turn when it's clear, which promotes safety for both you and other drivers. This practice is not only a fundamental rule of the road, but it also helps avoid potential accidents, especially since left turns often involve crossing multiple lanes of traffic. Therefore, the correct approach is to yield to oncoming traffic and wait until it is safe to make your turn.
