What does a green traffic light signify?

A green traffic light signifies that you may proceed if the road is clear. This means that vehicles are allowed to move forward through an intersection, provided it is safe to do so, and there are no obstacles or pedestrians in the way. It's important to ensure that there is sufficient space ahead to avoid any potential hazards or collisions.

Additionally, during this signal, drivers are expected to follow any other relevant traffic rules which may apply, such as yielding to any pedestrians crossing an intersection. While a green light indicates go, safety always comes first, and drivers should remain vigilant even when the light is green. Other options like needing to stop or turning left immediately do not pertain to the indication of a green light, which is primarily meant to allow cars to move forward.
