What does a yellow traffic light indicate?

A yellow traffic light serves as a warning that the light is about to change to red. When drivers see a yellow light, it indicates that they should slow down and prepare to stop safely before entering the intersection. This is an important signal designed to keep traffic flowing smoothly while also ensuring safety for all road users. It gives drivers the opportunity to stop safely rather than rushing through when the light is about to turn red, which could lead to accidents or violations.

The purpose of this signal is not just for the driver approaching the light but also to alert those who may be crossing or waiting to ensure they are aware of the impending change. Understanding the meaning of a yellow light is crucial for maintaining safe driving practices and preventing potential collisions at intersections.
