What does a yellow traffic light signify?

A yellow traffic light signifies caution and serves as a warning that the light will soon turn red. This signal indicates that drivers should prepare to stop if it is safe to do so. It is crucial for maintaining traffic flow and safety at intersections, allowing drivers the opportunity to react appropriately.

The intention of a yellow light is to alert drivers that they need to make a decision. If they are far enough from the intersection that stopping is safe, they should do so. However, if a vehicle is already close to the intersection, it may be appropriate to continue through rather than attempting to stop abruptly, ensuring the driver navigates safely while avoiding sudden stops that could endanger others.

In this context, the other options suggest actions that do not align with the purpose of the yellow light. Preparing to accelerate, going if already in the intersection, or increasing speed to clear the intersection can contribute to dangerous situations, particularly if other vehicles or pedestrians are present. Therefore, understanding the correct response to a yellow traffic light is essential for safe driving practices.
