Traffic signal lights are devices used to provide instructions to drivers, riders, and pedestrians, playing a crucial role in managing road traffic. They use three distinct colors to convey instructions:

  1. Red Light: When the traffic light is red, it instructs road users to come to a complete stop and wait until the next instruction is given.
  2. Yellow Light: The yellow light serves as a warning. It tells drivers that the light is about to turn red, so they should slow down their vehicles in preparation to stop.
  3. Green Light: When the traffic light is green, it indicates that drivers, pedestrians, and others have permission to proceed ahead, and the way is clear for them to move.

These color-coded signals are universally recognized and help ensure orderly and safe traffic flow.
