Final answer:
When in a dedicated turn lane with a green arrow, oncoming traffic must yield and you have the right-of-way. However, always verify that the intersection is clear, as vehicles may ignore the signal.
Step-by-step explanation:
When you are in a dedicated turn lane controlled by a green arrow, oncoming traffic must yield to vehicles in the dedicated turn lane. A green arrow signal indicates that you have the right-of-way to make a safe turn, and oncoming traffic is required to stop or remain stopped. However, it is always important to proceed with caution and ensure that the intersection is clear before completing the turn, as some vehicles might ignore traffic signals and speed through the intersection without regard to the posted limit. Despite the green arrow, drivers should not assume that all other vehicles will slow down; a vigilant check for potential hazards is advised.
