What does a circular green traffic light indicate?

A circular green traffic light indicates that drivers can proceed through the intersection with the expectation that it is safe to do so. This signal means that vehicles are allowed to continue their route, as long as it is clear of pedestrians and other hazards. Drivers should remain vigilant, however, as they still need to be aware of any other traffic rules in effect, such as right-of-way laws.

Additionally, while it is important to proceed with caution, the primary directive of a green light is to encourage movement rather than to indicate preparation to stop or the need to yield to pedestrians, which is not applicable at that moment. Combining these elements helps drivers understand the purpose behind traffic light signals and safe driving practices in various scenarios.
