What should you do when you see a green arrow pointing left at a traffic signal?

When you see a green arrow pointing left at a traffic signal, it indicates that you are allowed to turn left in that direction. However, it is crucial to ensure that the intersection is clear of any vehicles and pedestrians before proceeding. Waiting for traffic and pedestrians is important because, although the arrow gives you the right to proceed, you must still ensure that it is safe to make the turn. This practice helps prevent collisions and ensures the safety of all road users.

In this scenario, since the other options do not emphasize the necessity of ensuring safety before making the turn, they are not appropriate actions to take when faced with a green arrow. For instance, proceeding without checking can lead to dangerous situations if there are unexpected obstacles. Similarly, signaling is important when changing lanes or turning, but it does not replace the need to assess the intersection for safety. Simply checking for pedestrians also does not encompass the entirety of what is required before making the turn, as surrounding traffic conditions must be evaluated as well.
