What does a green light at an intersection mean?

A green light at an intersection indicates that drivers may proceed through the intersection, as it signals that it is safe to continue driving. This means that all vehicles facing the green light can move forward without the need to stop, provided the intersection is clear of pedestrians and other vehicles that may be crossing their path.

In traffic signaling, a green light is essential for maintaining the flow of traffic and indicates that drivers have the right of way over those facing a red light. However, it is crucial for drivers to remain vigilant and ensure that it is safe to proceed, as there may be pedestrians crossing or vehicles entering the intersection unexpectedly. The presence of a green light does not absolve drivers from exercising caution.

The other choices may represent different traffic situations. For example, a stop signal would mean all vehicles must come to a complete halt, whereas a yield signal indicates that vehicles must slow down and give way to other traffic or pedestrians. Caution signals usually mean to slow down and prepare to stop or proceed carefully, but do not imply that it's safe to go without verifying that the intersection is clear.
