What color light is always located in the middle?

The yellow light, which is always located in the middle of a traffic signal, serves the important function of indicating that the light is about to change. This cue is essential for drivers, as it signals them to prepare to stop if they are approaching the intersection and the light is about to turn red. By placing the yellow light in the center, it creates a clear visual hierarchy that helps drivers understand the transition between the different phases of traffic control.

The positioning of the yellow light is standardized under traffic control guidelines, ensuring uniformity and predictability across different intersections. This consistency is crucial for safe driving, as it helps drivers recognize and respond appropriately to changing traffic signals, ultimately enhancing road safety. The other colors associated with traffic lights—red, green, and blue—do not occupy the middle position in the standard traffic light arrangement.
