What does a green traffic light signal?

A green traffic light signals that it is safe for vehicles to proceed through the intersection or the designated traffic lane, provided that the way is clear. It indicates that the driver has the right of way and can move forward without stopping, as long as there are no obstacles in their path, such as pedestrians crossing or other vehicles that might pose a risk.

The emphasis on ensuring the way is clear is critical for safety, as it prevents potential accidents. Drivers should always be vigilant for any unforeseen circumstances that could affect the flow of traffic, even when the signal is green. This understanding reflects responsible driving behavior.

Other choices present scenarios that do not accurately represent the meaning of a green light. For instance, proceeding only if another vehicle is not present implies unnecessary caution when it is safe to go, while slowing down and preparing to stop suggests a misunderstanding of the signal. Waiting for the next signal change does not apply since a green light is an indication to go.
