What does a yellow traffic light indicate?

A yellow traffic light indicates that the light is about to turn red, and drivers should prepare to stop. This warning is crucial for maintaining traffic safety, as it alerts drivers that they should slow down and be ready to halt at the intersection. The purpose of the yellow light is to provide enough time for vehicles that are within the intersection or close to it to clear the area safely, while also giving those who are approaching the intersection time to stop before the light turns red.

Through this system, the yellow light helps ensure that the transition between green and red is smooth, minimizing the risk of collisions. It is critical for drivers to recognize and respond to this signal properly, as ignoring it and speeding up can lead to dangerous situations. Understanding this concept reinforces the importance of traffic signals in maintaining order and safety on the roads.
