What does it indicate if a traffic light is yellow?

A yellow traffic light serves as a warning signal indicating that the light is about to change to red. This means that drivers should prepare to stop if it is safe to do so. The purpose of the yellow light is to give motorists a moment to react, allowing them to either stop safely before the intersection or to clear the intersection if they are already too close to stop safely.

Understanding the implications of a yellow light is crucial for maintaining safety on the road. It conveys the message that the current state of movement is transitioning, and drivers need to adjust their actions accordingly. Drivers who speed up to pass a yellow light risk running a red light, which can lead to accidents and violations. Therefore, recognizing the yellow light as a signal to prepare to stop is an important part of responsible driving.
