What does a green traffic light mean?

A green traffic light indicates that vehicles are permitted to proceed through the intersection, provided that it is safe to do so. This means that drivers should assess the road ahead, ensuring it is clear of obstacles, pedestrians, or other vehicles that may impede their path. The expectation is to move forward or continue driving as long as the way is unobstructed.

The other choices do not accurately represent the meaning of a green light. Yielding to oncoming traffic usually applies to situations like turning left at intersections when there is an ongoing flow of traffic. Slowing down and preparing to stop would be more relevant for yellow lights, which signal a need to prepare to stop before a red light. Proceeding with caution applies to scenarios where there may be potential hazards, such as during yellow lights or in hazardous driving conditions. Thus, the clear directive of a green traffic light is simply to go, provided it is safe to proceed.
