What does a yellow traffic light indicate?

A yellow traffic light serves as a warning that the light will soon change to red, prompting drivers to proceed with caution. This signal indicates that the driver should prepare to stop if it is safe to do so, rather than rushing to clear the intersection. The intention is to prevent confusion and enhance safety by alerting drivers to upcoming changes in traffic signals, allowing them to react appropriately.

While some drivers may interpret a yellow light as a signal to speed up and cross the intersection, the correct approach is to evaluate the situation carefully and decide whether it is safe to stop or continue, keeping in mind that running a red light can lead to dangerous situations. Other options, like coming to a complete stop when the light is yellow, may not be practical in all scenarios, especially if stopping abruptly would create a hazard for vehicles behind. It's important for drivers to understand that the function of a yellow light is to signal caution rather than immediate action.
