The term "signal indications" specifically refers to the visible lights and phases of a traffic signal system. This includes the various lights—such as red, yellow, and green—that inform drivers and pedestrians of the appropriate actions to take at an intersection.

Understanding signal indications helps both drivers and pedestrians navigate intersections efficiently and safely.
