What is the significance of a yellow traffic light?

The significance of a yellow traffic light lies in its role as a warning for drivers. When a yellow light is illuminated, it signals that the light is about to change to red. Therefore, drivers are advised to prepare to stop. This stage is crucial as it communicates the need to reduce speed and be ready to halt, ensuring safety and compliance with traffic rules. The yellow light serves as a transitional signal, emphasizing that entering the intersection may pose a risk if drivers proceed without caution.

This interpretation is key in defensive driving contexts, where anticipating changes in traffic signals can prevent accidents. Understanding the purpose of the yellow light enables drivers to make informed decisions, prioritizing safety over the temptation to rush through an intersection.
