What does a green light indicate at an intersection?

A green light at an intersection primarily indicates that it is safe for drivers to proceed through the intersection. Traffic signals are in place to efficiently manage vehicular and pedestrian flow, and the green light signifies that vehicles may move forward or turn, depending on the specific rules for that intersection.

However, it is crucial to note that even with a green light, drivers must still remain vigilant. The requirement to yield to pedestrians crossing at the intersection is a significant part of this rule, ensuring pedestrian safety. Additionally, drivers must also be mindful of any cross traffic that may be approaching, especially if they are turning left or right at the intersection where oncoming vehicles might still have the right of way. This context reinforces the importance of being aware of the surroundings while proceeding at a green light.

The other options do not accurately reflect the proper behavior at a green light. Stopping for pedestrians may be necessary, but during a green light phase, it is not the direct instruction given to drivers. Preparing to turn does not encompass the full meaning of the green signal either, as the light also allows for straight travel. Lastly, accelerating quickly goes against the principle of safe driving; rather, a calm and prepared approach to the green light fosters better road safety.
