What is the meaning of a yellow traffic light?

A yellow traffic light serves as a warning to drivers that the traffic signal is about to change, usually from green to red. This alert encourages drivers to reduce their speed and prepare to stop safely. It is an important safety feature that helps manage traffic flow at intersections and allows drivers ample time to react to the signal change.

While some might interpret a yellow light as permission to proceed, it is crucial to understand that the primary purpose is to alert drivers about the upcoming change in signal. This aspect underscores the importance of cautious behavior, ensuring that all drivers are aware of the potential need to stop, thus promoting overall safety on the roads.

The other choices revolve around misinterpretations of the yellow light's purpose; for example, suggesting that it indicates a need to speed up could result in unsafe driving decisions and increase the risk of accidents. Understanding the true meaning of a yellow traffic light is essential for responsible driving and adherence to traffic laws.
