Final answer:
When facing a green arrow and a red light at an intersection, you may turn in the direction of the arrow after making sure it is safe to do so, while obeying the posted speed limit.
Step-by-step explanation:
If you approach an intersection and see a green arrow pointing in the direction you wish to turn while a red light is also showing, this means you are permitted to make the turn indicated by the arrow. The green arrow indicates that you have the right-of-way to make a safe turn in the direction of the arrow. However, it's essential to always proceed with caution, ensuring the intersection is clear of pedestrians and other vehicles before turning.
It's also important to obey the posted speed limit when making the turn, as speeding through an intersection can be dangerous. Remember that the red light applies to all other lanes and directions not indicated by the green arrow, so those lanes of traffic must remain stopped.
