What does a yellow traffic light indicate?

A yellow traffic light serves as a warning to drivers that the light is about to change to red. This notification is crucial to ensure safety at intersections. When a driver sees a yellow light, it is an indication that they should prepare to stop if it is safe to do so, rather than trying to rush through the intersection. This allows vehicles already in the intersection time to clear it safely, while also preventing sudden stops that could cause accidents.

The purpose of a yellow light is to provide notice that a change in traffic signal is imminent, which is why preparing to stop is the correct response. This helps minimize confusion and promotes safe driving practices. Understanding the meaning of traffic signals, including the yellow light, is essential for all drivers to follow the rules of the road and ensure everyone's safety on the streets.
