What does a green traffic light signify?

A green traffic light signifies that drivers are permitted to proceed through the intersection, provided that it is safe to do so. This means that if the intersection is clear of other vehicles and pedestrians, a driver can move forward without hesitation. The green light indicates that it is their right of way and they should act accordingly.

The other choices represent different meanings of traffic signals. For instance, stopping and waiting for a signal applies to situations where the light is red or there are other instructions indicating a stop is necessary. Preparing to stop correlates with yellow or amber lights, signaling drivers to slow down as the light is about to change. Yielding to pedestrians is crucial at crosswalks but is not exclusively indicated by a green light; rather, it’s a consistent responsibility regardless of the traffic light color.

Thus, the green light's primary function is to allow safe passage through intersections when conditions permit, reinforcing the flow of traffic while ensuring safety.
