What does a yellow traffic light mean?

A yellow traffic light indicates that the signal is about to change to red, signaling drivers to prepare to stop if it is safe to do so. This means that the light is a warning for upcoming changes in traffic flow, giving drivers time to react appropriately. It is crucial for safety that drivers understand this signal in order to avoid running a red light.

In this context, while it may be tempting to consider the other options, it is important to recognize that continuing through the intersection safely can only happen if the driver is able to stop in time before the light turns red. Stopping immediately no matter where you are may not always be safe, particularly if a vehicle is very close to the intersection. Similarly, speeding up is generally unsafe and can lead to dangerous situations. Understanding the meaning of a yellow light helps ensure that drivers respond appropriately in various situations.
