In traffic signal terminology, which interval follows the green interval?

The yellow change interval is the correct choice because it is a designated period that follows the green interval in a traffic signal cycle. This interval serves as a warning to drivers that the signal is about to change from green to red. During this time, drivers should prepare to stop if they are able to do so safely, as it indicates that the green phase is ending.

The purpose of the yellow change interval is to reduce the risk of collisions at intersections by providing a clear signal for drivers to react appropriately. It helps ensure that vehicles can clear the intersection if they are already within it when the light turns yellow, while also allowing others to prepare to stop.

Other options like the red clearance interval primarily deal with the period after the yellow, which allows vehicles in the intersection to clear before the light turns red. The wait interval generally references a condition rather than an interval of signal timing, and the transition interval is not a standard term used to describe the phases of a traffic signal cycle.
