What does a yellow light signal when you are approaching an intersection?

A yellow light serves as a warning that the signal is about to change to red. When you see a yellow light while approaching an intersection, it signifies that you should prepare to stop if it is safe to do so. This is crucial for ensuring safety not only for yourself but for pedestrians and other drivers as well.

The intention behind a yellow light is to provide you with adequate notice that the traffic condition is about to change, allowing you time to react appropriately. If you're able to stop safely without causing an abrupt halt that could endanger others, it is the recommended action. This prepares all drivers to be cautious and maintain control of their vehicles while navigating through or preparing to stop at the intersection.

In contrast to the other options, which may imply unsafe actions or misunderstandings of traffic signals, recognizing the yellow light as a cautionary signal is essential for safe driving practices.
