What does a yellow light indicate at an intersection?

A yellow light at an intersection serves as a warning that the light is about to change to red. It signifies that drivers should prepare to stop if it is safe to do so. The intention behind this signal is to provide drivers with a moment to react and make safe decisions regarding whether to stop or proceed, depending on their distance from the intersection and their speed.

The main goal of the yellow light is to enhance safety by reducing the likelihood of abrupt stops or collisions when the light changes from green to red. Understanding this allows drivers to be more cautious and attentive as they approach an intersection. The other options do not capture the essential meaning of a yellow light, which focuses on preparing to stop rather than proceeding carelessly or assuming no action is needed.
