What does it indicate if a traffic signal is yellow?

A yellow traffic signal serves as a warning to drivers that they should prepare to stop because the light will soon change to red. This transitional phase is designed to ensure that drivers are aware of the upcoming traffic signal change, allowing them time to react appropriately. When encountering a yellow light, drivers must assess their distance from the intersection and make a safe decision about whether to stop or continue through the intersection, depending on their speed and proximity to the signal.

The yellow light plays a crucial role in traffic safety, helping prevent accidents by signaling to drivers to slow down and be prepared for a potential stop. Understanding this helps drivers make better decisions and adhere to traffic laws, contributing to overall road safety.
