What does a yellow traffic light indicate?

A yellow traffic light serves as a signal to prepare to stop. When drivers see a yellow light, it indicates that the traffic light will soon change to red. It is important for drivers to be alert and to begin decelerating to ensure a safe stop before reaching the intersection.

This warning phase allows drivers who are already in the intersection to exit safely while informing those approaching the intersection that they need to slow down. The yellow light emphasizes caution and awareness, helping to prevent accidents by alerting drivers to the imminent change in traffic conditions.

Other options suggest actions that are not appropriate or safe responses to a yellow light. Someone speeding up or stopping immediately without assessing the situation could lead to dangerous situations, particularly if they were too close to the intersection when the light changed.
