What does a green traffic light indicate?

A green traffic light signifies that vehicles are allowed to proceed through the intersection, indicating that it is safe to go forward. The presence of a green light means that the traffic controlling devices permit movement and that drivers should clear the intersection swiftly while maintaining awareness of their surroundings. Although it's essential to ensure that the way is clear and it is safe to move before proceeding, the fundamental rule is that a green light grants the driver the right to advance.

Other options mention conditions or caution that might apply in different traffic situations, but the primary purpose of a green light is to communicate that vehicles should move. Therefore, it is the driver’s responsibility to ensure that proceeding is indeed safe before doing so.
