What should a driver do when they see a yellow traffic light?

When a driver sees a yellow traffic light, the appropriate action is to prepare to stop. A yellow light serves as a warning that the traffic signal is about to change to red. It indicates that the driver should slow down and make every effort to safely come to a stop before entering the intersection, unless stopping would create a hazard.

In this context, speeding up to clear the intersection is risky and can lead to accidents, especially if the light changes to red while crossing. Ignoring the yellow light and proceeding could also cause dangerous situations, as it does not respect the transition phase of the traffic signal. Changing lanes immediately is not advisable either, as this could lead to unpredictable movements and increase the likelihood of a collision, particularly in busy intersections. Hence, preparing to stop when a yellow light is displayed is the safest and most responsible action.
