What does a green traffic light signify?

A green traffic light signifies that drivers are permitted to proceed through the intersection or continue driving in the direction indicated by the green light, provided it is safe to do so. This means that drivers should assess the situation around them, including checking for any pedestrians, cyclists, or other vehicles that may not be adhering to traffic signals. The emphasis is on safety, allowing drivers to continue only when it is prudent, thereby promoting a flow of traffic while ensuring that all road users are considered.

The other options describe actions that do not align with the purpose of a green light. Stopping immediately would contradict the meaning of a green light, while proceeding only if necessary does not capture the full allowance given to drivers. Yielding to pedestrians is important but typically applies more to crosswalks, and while drivers must be cautious of pedestrians regardless of the traffic light color, the green light primarily signals that it is safe to move forward when conditions permit.
