What does a green light mean?

A green light indicates that you may proceed through the intersection, provided it is clear and safe to do so. This signal gives drivers the right of way to move forward while signaling that they must still be alert for other traffic and pedestrians who may be present. It's crucial for drivers to ensure that there are no obstacles or other vehicles in the intersection before proceeding, can reduce the risk of accidents and ensure the flow of traffic continues smoothly.

The other options suggest different actions that are appropriate for other traffic signals or circumstances. For instance, stopping and waiting is appropriate for a red light, while yielding to pedestrians is a priority regardless of the traffic signal. Understanding the meaning of a green light helps drivers effectively navigate intersections and contribute to overall road safety.
