What does a green traffic light indicate?

A green traffic light indicates that vehicles are permitted to proceed through the intersection. It means that the way is clear for drivers to move forward, and they should do so with the expectation that traffic flow is active. While "proceed with caution" might apply in certain circumstances, such as being aware of pedestrians or other vehicles that might not follow the rules, the primary meaning of a green light is to allow movement.

The other choices reflect actions that do not correspond to the meaning of a green light. Coming to a complete stop is indicated by a red light, while preparing to stop aligns with an amber light, indicating the need to halt before entering the intersection. The option concerning pedestrians is important to consider when driving but does not change the fundamental instruction that a green light indicates it is safe to proceed.
