What does a green traffic light signify?

A green traffic light signifies that vehicles and pedestrians may proceed through the intersection if it is safe to do so. This indicates that the traffic flow is permitted and that the road ahead is clear for movement. It is crucial for drivers to remain vigilant, checking for any obstacles or pedestrians before proceeding, as a green light does not guarantee that the path is entirely free of hazards.

While other choices provide instructions relevant to driving, they do not accurately reflect the meaning of a green light. For example, stopping or preparing to stop relates to different traffic signals and symbols indicating caution or the need to yield. Therefore, understanding that a green light allows for movement, contingent on the safety of the surroundings, is essential for safe driving practices.
