What does a yellow traffic light mean?

A yellow traffic light serves as a warning that the light is about to change to red, indicating that drivers should prepare to stop. This signal is important for maintaining safety at intersections as it warns drivers that they should not proceed through the intersection if they can safely stop in time.

When a yellow light is illuminated, it is critical for drivers to assess their situation. If they are far enough away from the intersection, it is advisable to slow down and stop rather than trying to rush through. Conversely, if a driver is already close to or within the intersection when the light turns yellow, they should continue through in a safe manner. The key aspect is that it communicates urgency and a need for caution, rather than indicating that it is safe to cross or speed up. Understanding the implications of a yellow light is crucial for driving safely and avoiding accidents at intersections.
