What does a delayed green light signify at an intersection?

A delayed green light at an intersection typically indicates that one direction of traffic has a green light while the other direction remains red. This means that vehicles facing the delayed green signal are given the go-ahead to proceed, but drivers coming from the other direction must remain stopped until the light changes. This function is designed to manage traffic flow efficiently while ensuring safety at intersections by clearly delineating which movements are permitted and which are not.

In contrast, the other options do not accurately represent the situation with a delayed green light. For instance, having both sides with a green light would create confusion and potential hazards, as vehicles would be crossing each other's paths without clear direction. Similarly, saying traffic is about to stop or requiring a complete stop does not define the function of a delayed green light, as that specific light indicates a change in the usual traffic signals in favor of movement for one direction while stopping another.
