What does a yellow over green traffic light mean at an intersection?

A yellow over green traffic light at an intersection indicates that the green signal is about to change to red. This serves as a warning to drivers that they need to prepare to stop. The correct interpretation of this signal is that you may pass through the intersection, but you should only do so if you are too close to the stop line to halt safely. This condition emphasizes the importance of being alert and prepared for changes ahead, thereby promoting safety at intersections.

Emergency situations and variable traffic conditions can lead to drivers hesitating or misjudging their stopping distances, which makes understanding this signal crucial. Accordingly, there are various behaviors encouraged by the other choices that do not align with the proper handling of a yellow over green signal, such as speeding up to try and pass or proceeding without caution.
