What is the meaning of a yellow traffic light?

A yellow traffic light serves as a warning to drivers that the light is about to change to red, signaling that it is time to prepare to stop. This indication is crucial for maintaining safety at intersections because it alerts drivers that they should not enter the intersection unless they are already too close to stop safely. Understanding this warning helps prevent accidents, as it encourages drivers to slow down and be ready for the upcoming red light, thus reducing the likelihood of running a red light which can lead to collisions with cross traffic. This proactive approach is essential for safe driving practices.
