Who has the right-of-way at an intersection when the light is green?

When the light is green, the fundamental rule of traffic signals indicates that vehicles can proceed through the intersection. In this case, oncoming traffic refers specifically to vehicles that are approaching the intersection from the opposite direction, and they typically have a red light or are yielding to the right-of-way laws that govern intersection crossing.

The reason oncoming traffic is considered the correct answer here is that green lights allow vehicles to move forward, while any traffic that is required to stop or yield (like those with red lights or pedestrians crossing against the signal) must not impede this movement. Vehicles are expected to maintain their right-of-way, meaning they can continue through the intersection safely without having to yield to other road users who are not given the right-of-way by traffic signals.

While pedestrians have the right to cross at crosswalks, and bicyclists must observe the same rules as vehicles at intersections, they do not take precedence over vehicles moving through on a green light. Overall, the scenario depicts standard traffic rules where the green light grants right-of-way to vehicles, facilitating smoother traffic flow and reducing confusion at intersections.
