What does a traffic signal turning yellow indicate to drivers?

A traffic signal turning yellow serves as a warning to drivers that the light is about to change to red. This indicates that drivers should prepare to stop and make a safe decision regarding their next move. The yellow light gives them a moment to assess whether they can stop safely before reaching the intersection or if they are too close to the stop line to do so without risking an abrupt stop.

Understanding the yellow signal is crucial for maintaining safety on the roads. It ensures that drivers are aware of the impending change in traffic conditions and can respond appropriately to prevent accidents. Recognizing the yellow light as a cue to prepare to stop reinforces safe driving practices and helps maintain orderly traffic flow at intersections.
