What does a yellow light indicate?

A yellow light serves as a warning to drivers that the traffic signal is about to change from green to red. This signal is designed to alert you that you need to prepare to stop if it is safe to do so. The intention behind the yellow light is to provide a transition period, giving drivers adequate notice to safely stop before entering an intersection, thus preventing potential accidents that could occur if they rushed into it without warning.

While it may be tempting for some drivers to speed up to clear the intersection, doing so can lead to dangerous situations, especially if they encounter vehicles coming from the side or pedestrians attempting to cross. It is important to remember that the yellow light is not an indication to proceed at full speed. Thus, the best course of action when encountering a yellow light is to assess whether stopping is safe and appropriate.
