What does a green traffic light indicate?

A green traffic light indicates that you may proceed through the intersection if it is safe to do so. This means that when the light turns green, drivers have the right of way to continue moving forward, provided that the intersection is clear and there are no pedestrians or other vehicles obstructing their path. It is vital for drivers to exercise caution and assess conditions before proceeding, as a green light does not guarantee safety.

While some options suggest other actions, they are not in line with the standard meaning of a green traffic light. Stopping for a light when it is green or preparing to stop does not apply, as the signal clearly indicates that movement is allowed. Similarly, while turning left is permitted when safe, a green light typically allows for straight movement or other maneuvers as long as they do not interfere with traffic rules. Hence, option A correctly captures the main directive of a green light: to proceed when it is safe.
