Final answer:
A green arrow on a traffic signal allows you to make the turn indicated by the arrow, signifying that oncoming traffic is stopped and that you have the right of way for that specific direction.
Step-by-step explanation:
Yes, a green arrow on a traffic signal means you are permitted to make the turn indicated by the arrow. This is a common convention in traffic signals where a green arrow provides the right of way to drivers for a specific direction of travel. It often also signifies that oncoming traffic is stopped by a red light, making the turn safer. However, drivers should always remain alert for any pedestrians or other obstacles before completing the turn. It's important to know that traffic rules and signage can vary by location so always pay attention to local rules and regulations.
