What is indicated by a yellow light?

A yellow light serves as a warning that the traffic signal is about to change to red. When you see a yellow light, it indicates that you should prepare to stop if you are in a position to do so safely. This is crucial for maintaining safety on the road, as it gives drivers the opportunity to react appropriately to the impending change in traffic conditions.

While it's important to consider the context of the situation, this signal is specifically designed to alert drivers to slow down and prepare to halt their vehicles before entering the intersection. It encourages responsible driving behaviors and helps prevent accidents that could occur if a driver were to ignore the warning and continue through the intersection recklessly.
