What does a yellow traffic light mean?

A yellow traffic light signals that the traffic signal is about to change to red. This is an important warning for drivers, indicating that they should prepare to stop and not enter the intersection unless they are already too close to safely stop before the light turns red.

The purpose of the yellow light is to ensure safety by alerting drivers to the imminent change in signal color and giving them time to react appropriately. Ignoring this signal could lead to dangerous situations, such as running a red light or causing accidents at an intersection. Understanding the meaning of a yellow light is crucial for maintaining the flow of traffic and ensuring the safety of all road users.
