Final answer:
A green arrow displayed alongside a red traffic light typically indicates that you are permitted to turn in the direction of the arrow, while other traffic must remain stopped.
Step-by-step explanation:
When a green arrow is displayed at the same time as a red traffic light, it generally indicates that you have the right of way to turn in the direction of the arrow, while traffic in other directions must stop. If the green arrow points to the left, you are allowed to turn left; if it points to the right, you can turn right. The green arrow permits you to proceed with caution in the direction indicated by the arrow, even while the red light is telling other traffic to stop. However, you should always ensure that the path is clear and it is safe to proceed before turning. Also, the exact rules can vary by jurisdiction, so it's important to be familiar with local traffic laws.
